How long to aerate water? Thread starter Bongofury Start date Jan 5, Bongofury Need a light? Joined Mar 19, Messages Reaction score How long to aerate water before watering plants? I'll be using a 35 gallon rain water barrel, a 4 way valve and 4 aeration stones driven by a 60 gallon air pump.

This process is more efficient on large lakes because there is a large open area for the wind to blow across the lake with less blockage from trees, hills, and buildings, and the larger surface area allows the waves to travel further.

Small ponds that are surrounded by trees or other obstructions that block the wind do not receive as much oxygen from wind. Photosynthesis is the process plants use to create energy. The aquatic plants will use sunlight and carbon dioxide to produce energy in the form of cellulose and release oxygen as a byproduct. More weeds is not always a good thing for your pond even though they are producing oxygen. During the daytime when the pond is receiving sunlight, photosynthesis can release oxygen into the water for the fish and bacteria to use.

However, during the nighttime hours when there is no sunlight, photosynthesis stops and plants actually start to use some oxygen instead of producing it, and as the night progresses, the oxygen levels steadily drop. Also, once the plants die off, the extra decomposition taking place also uses up available oxygen.

Here is a link that might be useful: koi club. Oxygen loss is also determined by the temperature of the water. The warmer the water the quicker it loses oxygen and thus harder to keep oxygen in the water when the pumps are turned off. I have my pond ran off 1 circuit and use an in-line light switch that I can flip to turn off the pumps when I need to do a little maintenance or sometimes I need to switch it when its very windy outside so I don't lose a lot of water from my fountain and spitter.

My pond is only a 50 gal pond so oxygen loss would take quicker affect on the fish and I have already went 2 days with my pumps turned off and never had a problem.

If you are worried about oxygen loss for the 1 day you have the pump turned off you can add some fresh water to the pond to give it some oxygen. This link will lead you to an article by Norm Meck who is a leader on water quality.

It discusses dissolved O2 and other chemicals. I would recommend that you read all the articles as they are very informative. Here is a link that might be useful: Water Chemistry. If you keep an aerator on, you will be fine. Also, the cover will keep the water temperature lower and thus, keep more oxygen in the water as Jason34 indicated. Do not let the tarp lay on the water, but keep it elevated as the oxygen exchange occurs on the surface. I honestly wouldn't use a tarp.

Actually I wouldn't use a cover at all. If the sun beats down on the cover it will heat up everything its covering. Obviously I would leave the cover lifted off the water like magnoliaponds said to allow air to run under it.

If you do use a tarp go with as light of a color as possible. I agree, Jason But if the poster's original concern was they are out there spraying Agent Orange I am dating myself then a light weight, light colored tarp is the best alternative. The heat is only one reason to keep it elevated a few inches, it allows heat to escape and the natural exchage if surface oxygen.

The required use of an aerator will keep a flow of cooler air in and through the tent. Got to watch when using a tarp though because they are woven thus liquid can still seep through it. If you can get ahold of an actual plastic cover youll be in business.

Shalom - maybe a clear plastic paint drop cloth - cheap, easy to store or even throw away. Indem Sie weiterhin auf der Website surfen bzw. Mehr erfahren. Ultimate Lighting Sale. Bathroom Vanity Sale. Bestselling Chandeliers and Pendants. Sign In. Join as a Pro. Houzz TV.
