The strainer o ring gasket make sure it is not dried out cut or broken.
Air bubbles from pond floor.
While fishing at 15 m deep pond at my backyard i saw a few bubbles of air appearing on the surface of the water.
Remember the problem lies from the pump forward.
I launched a rowboat into it the other day and the oars kept coming up with a ton of weeds.
There is no foam.
Air bubbles in the water that settle on top of the liner are a normal part of pool operation and usually occur when the pool is being filled.
This will re wet the sealer and help it lay out again releasing the air and gas bubbles.
Lube tube is a great product to lubricate dry o rings.
As a result any condition i e sunlight that causes the air to warm and the moisture to vaporize causes expansion and increased pressure within the concrete.
The surface is clear.
The pond is a basalt depression that is surrounded by cattails and filled with weeds.
How to shock a pond.
Coating application over moisture.
The increased pressure on the backside of the coating often causes bubbles to form.
Sometimes reapplying the same sealer will fix the concrete blisters and bubbles again try this on a small area first.
An excess of proteins in pond water can be the culprit causing chemical reactions when conditions are right that almost look like soap bubbles in the pond.
If you are taking in air you will be putting out air.
This much finer stream from just 1 litre of air will have effectively tripled the surface area of the pond.
Little tiny air bubbles were coming up through the weeds.
As mentioned previously.
Are they threaded all the way in.
Here is a checklist that includes a few areas to check and why.
Bubbles do not always appear on the surface of the coating.
Most tadpoles have to breathe air to survive but hatchlings are too feeble to break the skin on a pond s surface caused by water tension so they suck air bubbles instead.
This same solution will sometimes work with water based sealers just try it on a small area first.
Check the drain plugs on the pump.
They are usually milky white and you will often see the bubbles under water falls or over the diffusers or airstones as the rising bubbles movement seems to ride across the surface tension.
If the air stone produced a much finer stream of bubbles say 10 000 then their total surface area is more than doubled to 10 4 m 2 making the new effective surface area of the pond equal to 15 4 m 2.
