What else do you think I should be dosing?
Plants that flower (like a pepper) need Phosphorus to help create the flower/seed. If you intend to just grow green vegtables you can get away with out having to worry about Phosphorus.
Check out Plant nutrition - Wikipedia, the free encyclopedia
for more info on what plants generally need to really do well.
There is a way to grow flowering plants using aquaponics without having to really dose Phosphorus, however you need to use a growing media and introduce worms to create the phosphorus for you. It sounds liek you are wanting to use floating nets though.
Check out: How to Grow Tomatoes in Aquaponics | eHow.com
for a guide that is fairly simple and strait forward. They use tomatoes as an example. I found it using google while trying to gather information as i haven't research aquaponics in a year or so and wanted to be sure i wasn't giving you crappy advise lol.
I would be really interested in seeing how you make out as i am planing a aquaponics system in the future (was going to be sooner but we decided to build a house first lol). I will be following along.
Sorry about the late reply was away from the computer for a while.
