What's up with tilapia? Hybridizing like mad?
(I remember when tilapia filets hit the supermarket.
It was never seen here before maybe 2004?)
Now I have a friend with 2 acres and a bunch of old bath tubs who wants to set up big this aquaponics rig with tilapia.
Somehow I really expect it to turn out more like Dave's Fish Rescue rather than produce serious food, but tilapia? They must like the summer heat, because we have 3 mos in the hi-90s ~ lo-100s here in the SSJV.

I started seeing Mozambique Tilapines back in the 60s and 70s, I got my first ones around 63.

Starting a new thread about the Tilapia branch of this thread......
Buying Mozambique Tilapia by the pound

Yeah it's about $4 a pound more in the store than what you're paying buddy.

But then I'm buying fresh fillets

I guess to me keeping tilapia would be like having a a pet cow, because eventually you know you're going to eat it.

I agree that a siphon really isn't the best way. A siphon requires a siphon-keeper to keep it going 24/7/365. The grilles plug up, they suck bubbles. Decaying bio-crud inside creates bubbles too. Enough bubbles and it quits, but a fast siphon or one with big head pressure may survive them. A slow siphon won't.

A water pump will help, pumping bleed water into the siphon 24/7, but that's no good for you as you don't have a sump to reclaim the wash-water.

I have lots of siphons going and I am the human siphon-keeper.

Bugs, fish, and especially Snails love to get in a siphon and hang out there because it's dark and there's yummy bio-film galore after it ages in. Anyhow they grow big enough to plug the tubing, and I came to find a 1" dia snail had sill got in a clear siphon, and was bobbling in the flow like the ball in a gas flowmeter. I told my wife to "come see my new snail barometer."

He was like that a while and I suspected he was waiting for the ride to end. I rescued it and made my assy more snail-proof.
