Our rear garden had a natural slope, with a bigger gradient where the pond now is. We got the patio laid and the wall put up, shaped it like this to incorporate a pond into the build. It around a year old now

Long time lurker here who finally gave into having a pond!! We’ve almost finished digging the pond - I think only having another day’s worth of digging to go. I’ve got a preformed 750 gal pond that we’re digging out the shape of. Would you backfill some of the depth with sand underneath the liner? I was just going to put it on top of the soil and fill in any empty areas with more soil but my friend said I’d need to use soil so the pond liner can breathe.

Hi,

Dug out a new pond last August. Just had aerators, plants and small homemade waterfall. I added an oase biopress filter and pump about two weeks ago. But ammonia levels are now high. 0.5ppm from api test water kit. I did about a 15% water change yesterday before testing. Tested this morning and noticed the high amonia.

I had used seachem stability when adding the pump and filter. But also there is a uv light in the filter and reading up online I think I should have actually had that off for the first few weeks is that correct?

Are 25% water changes and turn off the uv light my best course of action? Or what’s all yours opinions on buying something like api quick start. Open to all suggestions as want to make sure my little fishy’s don’t get harmed.

Video of pond to give and idea of size, there’s 7 small fish and have only started feeding again the last few days (should I stop this until ammonia back on track). Also added some new plants yesterday.

A few years back, mother tugged a wormy parasite from one of her bigger goldfish. We have speculated with Google that it was an anchor worm. Last year and this, we've spotted some little white bumps on a couple that were assume will turn into some similar wormy parasite. Earlier in the year I gave a treatment of the luminous green bacteria and virus treatment, and a few days ago I used right tablets of Parazin P (?) lice & anchor worm treatment. Impossible to get a good pic, but this sort of shows what I have seen. It's so sunny here I can't really see how detailed the pics are! Any tips? Cockapoo for size reference .

What's the best way to remove this old concrete lining thats peeling? Which coating should I line it with?

Wire brush is very hard and taking very long

So my husband and I are wanting to buy this property with a naturally occurring pond on the property. The Sellers have added some goldfish to the pond, but there is nothing else added to this pond. We had to sign paperwork that stated that this is a private natural pond on the property that is not man made.

My question would be, what kind of maintenance would a naturally occurring, God-Made pond need?

P.S. we have a water-loving dog and plan on having livestock, would they safely be able to use said pond if not maintained.(we already know about the snakes and would check the water before releasing anything to the water)

Bought a house with an abandoned pond that I’d love to revive. It has leaks and I’ve identified a few cracks.

It is concrete and I think it has a liner or old layer of sealant of some type. Which is old and flaking in some spots.

Im between either using Liquid Rubber to do patch work on the cracks Or Laying a EPDM liner .

It’s about 30’ x 18’ x 3’.

But really my question is , how would I work around the bridge’s column for the liner?

Please excuse the terrible picture, all I had to hand.

As you can see, there is a lot of the liner exposed on the left hand side. We were hoping to cover it, potentially by draping with some sort of mat and seed plants or grass into it. We've been looking at coconut coir grow mats, would these be effective? Thank in advance

i've been looking everywhere online for a round patio pond like this, or even just a planter to diy the pond myself. i just need the material to be safe for my cats to drink out of because i'm sure this will be tempting for them whether i put fish in it or not!

i'm new to this sub and have never built a pond before. any advice is much appreciated!

In the fall we bought a home with a small pond in the backyard and would appreciate suggestions in how best to maintain it. Winter has just ended (Canada) and we have just turned the waterfall back on, but in the fall we found out there must be a leak in the pipes somewhere (we think the ones under the rocks to the waterfall, the water level lowers considerably after running the waterfall for a few days then needs a top up) so we will likely need to make some changes. The current system is homemade by the previous owner. There are about 15 gold fish in the pond.

What filter, pump and piping system would you recommend to get clear water and keep the pond and fish healthy. Please mind we are on a budget. Thanks!

Putting together all the items I need for my pond. I have a Firestone liner for now and I have plenty of dirt. I’m curious about options for keeping the water moving so it doesn’t turn into a mosquito breeding ground. Is a bubbler my best option and if so what would you recommend? I plan to use the pond for wildlife and don’t intent to have fish at this time if that matters

Looking for some help. I have an approximately 1/2 acre pond, it smells terrible and I have fish dying. This happened last year about the same time but not the year before. The darker color of the water is pretty close to the usual color of the pond and the lighter color is new and the fish started dying right after it showed up. The pond is not spring fed, the only water source is rain. We have about 12 ducks. In the third picture you can see that I am trying some emergency aeration. I have a sump pump and a large pond pump from Lowes. Now that I know this is not a one off thing I will definitely get to the bottom of it to make sure it doesn't happen again but that will take some time. Is there anything I can do today to prevent more fish from dying?

Hi,

My dad has built a large natural swimming pool, which has a central area for swinming and a large shallow outer perimeter where plants can grow. The water is circulated through the ground using air pumps. Our issue is we can’t get the plants to properly establish due to blanket weed - the blanket weed will coat the plants preventing them from growing, and causing them to die back, which gives the blanket weed even more nutrients to feed on and grow. We have been manually removing the blanket weed from the plants and the outer perimeter, but this is not sustainable because the blanket weed will inevitably grow back faster than the plants, and us removing it also disturbs the area where plants are growing because we have to wade around removing it.

We understand that once there’s a sufficient plant population the blanket weed will be outcompeted, but our issue is reaching that point. Does anyone have any suggestions for methods we can use to tip the balance and allow the plants to grow? We have seen options such as getting the water tested, using treatments to remove nitrates/phosphates, using a filter (not sure which types of filters can remove these types of nutrients), algaecides (which we want to avoid using).

Any help much appreciated!

I'm digging a pond into a slight slope in my backyard. It's approximately 10'x10' (slightly L-shaped), and it'll be 2' deep in the deep section. However, the back wall is easily 3' wall because it's been dug into a slope.

I'm trying to figure out the best way to deal with the wall of dirt and placing the liner, so that a) the wall is retained, and b) dirt and runoff are prevented from entering the pond on that back wall high side. My likee won't be big enough to make it up over the tall wall on all sides, but it'll be close. The liner is 15'x15'. Any advice?

I'm planning a bog filter in a 20 gallon plastic tub. The plans I've seen show the feed hose coming in the top and going to the bottom. Doesn't it make more sense to feed the gravel bed through a bulkhead fitting at the bottom?

Found this on my water soldier. I’m hoping amphibian but more likely to be an insect, can anyone enlighten me? :)

Our pond has a small leak. It developed in the last month or so. How can I find where it is and can I repair it? It is with a liner. The leak is on the top part as I don't see water loss when I turn off the waterfall.

Im getting this persistent brown/grey fuzz on my pond plants - is it a type of algae? All water indicators appear to be fine. It's somewhat unsightly so prefer to get rid of it, but also happy to live with it if it's normal/common/beneficial

Does anyone know what this plant is sprouting next to the pond? We bought this house about a year ago, and everything had kind of wilted due to the GA summer heat.

Hello all

I have tried searching for some time and have been unable to find anything on this.

I have an Oase Filtral UVC 1500 pump, and there appears to be a leak somewhere, possibly on the bulb housing where the power cord enters the housing. And it might only be when there is a tension on the cord.

I wanted to empty my pond in order to clean it, and as I was connecting a hose to the outlet on the stand pipe when I accidentally tugged on the filter and could feel the electricity in the water. I immediately unplugged it and took it out of the water.

Has anyone got experience with this and is there a way to disassemble the housing in order to check the seals?

I have the required training to work with electrical equipment in water, but the disassembly of the housing is a bit tricky. All I can see is four small taps that needs to be released, but it seems like there is more holding it together and I don’t want to damage it.

hi all, i am rather new to the pond game. im living at a house with a ≈300 gallon or so pond thats been dormant for atleast a decade. a couple weeks ago i scooped everything out and put in a pump and bog filter. though ive learned filters are more meant for green discoloration. when i scooped everything out there was maybe still 30 gallons of water or so still at the bottom, and then i just filled the rest with clean water. i knew itd be a little murky, but i havent been able to see more than 2 inches into it from the beginning. i know doing a full water change and scrub out is likely the necessary step, but im curious in anything i could maybe do.

This was a pond at some point. We recently purchased the home and it already wasn't in the best of shape, but it had a relatively healthy ecosystem and at least a foot of water, so we let it sit until we could turn our attention to it.

Hurricane Helene pushed that up on our project list. We lowered the water level to prevent flooding before the storm, and lots of gravel from our road, plus trash, made it's way into the pond. Resulting in what you see now.

While the level is low, now would probably be the time to get in there with some equipment and clean it out, but I want to be conscious of how we go about it. There water is low, but it's always been clear. And it is spring fed and then overflows into creeks that feed the river further down the mountain. So there's always got fresh water coming in and going out, it doesn't smell, and there's tons of tadpoles, salamanders, etc. Apparently, at one point, it was even a trout pond.

My understanding is the sludge at the bottom of beneficial, but it's a solid 2+ feet deep in most parts. Discovered that out when we first moved in and my dog decided to take a dive. Cue instant panic, lol.

Are there any things we should know before we move forward so that we can be good stewards of this critter paradise?
