Thanks for the help TCLynx. Will look into them.

Different topic. I have found 3 dead tilapia in the last couple of days. They were all small one -- a couple of inches at most -- and my theory is that the bigger fish (4 inches or so) are denying them food or injuring them. Or something? The fish don't look sick or hurt or anything. No lesions or growths. Any theories?

They do make big tank liners and there are above ground pools that are designed for growing out fish.  Aquatic Eco Systems has products that you might want to look into.

Thanks for the input. Anyone have any other suggestions on what tanks we can use? We need minimum 5000 gallon tanks to make it worth while.

Yes, midge fly larvae are excellent supplemental fish food, and they do help a bit with detritus.  Virtually every system has some, even if you never see them.  If the eggs are laid in a tank with no substrate for the larvae to hide in, you'll be able to see them better.  They live their early lives inside of a "tube" and poke their heads out to eat whatever is in their vicinity.  If you see a bunch of brown tube like things on the bottom of a tank, that's likely the old homes of some midges.

 Midge fly larvae are sold in the aquarium trade as blood worms, and are fairly expensive.

MFL is a favorite food of trout.  As a result, fly fishermen often use flies (lures) that look like MFL.  I've got a bunch myself actually.  Work great in trout streams in the Missouri Ozarks areas.

some people have used kiddie pools successfully Christian, however, some pool liners contain chemicals meant to kill algae and bacterial growth and can become toxic to fish.  I'm not sure how to tell which pools contain the toxic chemicals and which do not.

Some people have used the pools and just killed batch after batch of fish.

Depending on the size of the pools, they may be difficult to net the fish out of.

Depending on the type of pool it might be difficult to plumb through it or support grow beds over it.

Not saying it wouldn't work but there will be some challenges and risks to trying it.

The pools would be used for aquaponics. Why do you think they would not work?

@Jon @TC - pretty sure they were Midge larvae.  I definitely had the the little red worms by the thousands and the adults match pictures I've found.  That explains why the mosquito fish & rings didn't work and why I wasn't bitten by them.  I always thought the ones I was vacuuming up looked kind of large for a baby mosquito.  Thanks for the info!

Yea, I was gonna say, how were the mosquito adults laying eggs in the gravel in a tank?  They do it from the surface, and the mosquito larva are free swimming wigglers.  It would be the midge larva living down in the gravel.  And midge larva are good fish food and apparently in some tests feeding some midge larva to the fish increased the feed efficiency of the other food given as well.
