Sure, two of them! :-)
1. Are you in California? If so, can you comment on how easy/hard it is to get Tilapia for a setup like this? I know someone living near Campbell who had trouble legally getting any of the Tilapia species that are suitable for aquaculture. The California department of Fish and Wildlife apparently considers most or all Tilapia to be invasive species. (Oddly enough, I see T. buttikoferi in pet stores every now and then, but they're too expensive to eat.)
2. Is using PVC really that bad? I've been in the aquarium hobby for over half my life now, and I can't remember ever seeing a single DIY aquarium plumbing project that didn't use PVC. PVC seems particularly ubiquitous for elbows and fittings--how hard/expensive is it to get PEX fittings at retail?
- jsilence 10y agoPVC-U is just fine for aquaponics. It can be considered food safe. PE is nicer to recycle, but when you have a sound system design you are not going to change and discard pipes very often.
- ph0rque 10y ago1. I'm not in CA, but from what I read it seems like raising tilapia in CA would be legally difficult. You do have other fish choices, such as catfish crappie, perch, and bluegill. 2. I haven't been able to find a lot of hard facts about PVC, other than the fact that it supposedly bad for fish you want to eat eventually. In any case, PEX piping and fittings are readily available online and in Home Depot and Lowes stores.
