Airation

[Oldhead]

Does anyone use airation or is a waterfall good enough? Will too many plants cause the O2 levels to drop at night? One article i read for preparing your pond for winter talked about plants using up the O2 at night.

i use both.. my pump is a hagen optima, hooked up to 2 3" top fin volcano air stones same pump if bought rated for outside use is $70.00, it costs under $30.00 but you have to put it in a tupperware storage container becase its rated for indoor use. but it puts out some air. it will power 7 1" airstones. i use it outside and in the basement pond..its been running nonstop for a year. it also has a flow adjustment

yes i use one too ... its great for shallower parts of my pond and fish seem happier and move about more ... and yes plants do use up oxogen at night

a good cascading waterfall is hard to beat.

Plants don't use oxygen, they just don't produce any during the night. They need light for photosynthesis to take place.

Algae and some other plants do consume oxygen at night.

the plants known as "oxygenators" ABSOLUTELY use oxygen at night.
