The plankton likes to stick to it but turning off the falls for a while it dries and dies. There are three pumps each for a diff area, so I can alternate.
I am so excited, we went cast netting in a nearby lake this eve and caught two one foot long near as I can identify thus far: armored catfish. Absolutely beautiful! A week or so ago we got one one foot telapia!
The zep septic stuff combined with a new application improved my clarity to almost a foot.
It is all good!
I'd love to show you a picture of these beauties, we took before we released them. Near as I can figure from reading here how to identify the sex of tilapia, I think these are both male catfish. Hence, if they are a nuisance at least that won't be reproducing.
Sorry to change the subject, just soooooooo excited!
Thanks for asking!
