Unfortunately I started construction on my first AP system before I found the Newbie mistakes thread. But everything seems ok so far.
I have a 1200 gallon fish tank (in the ground)
Three growbeds, One of which is only 5" deep. (The bell siphon is a little iffy)
Grow towers and NFT system are next to research. I just wanted to get my feet wet before committing to a larger system.
I had planned to run the system on one pump and still think I can with the use of an indexing valve.
I left the spaces for all you aqua elders to tell me what I did wrong and how to fix it. The tank is the only thing I am not really interested in changing right now. It is in a 19' x 23' building and that is a big hole to have to fill.
