Sorry to hear about the sad fish. Do you know what temperature the fish tank water dropped to.
Mine got down to 50.1F and the fish don't look pleased, but they're not struggling either.

"I noticed a drop in temperature output of the solar panel and went out to check. This is what I found.
Just kidding, but I've discovered a new way to heat water. Orange Cat Water Heater. Patent Pending.
This is the last of the beans. They've done well. I think I'll pull the plants soon.
The cherry tomatoes are in full swing and the Romanos are just starting. Lots of healthy eating in front of me.
I'm still in trial and error mode at the moment myself. One of the positives of using the irrigation tubing is that I can move the solar panel around, but I'm quickly coming to the conclusion that I need to get the panel set in…"
"@ Bob Wohl
How is it done? By standing in the plumbing aisles in Home Depot staring at all the multitude of connectors and adapters and fittings and coming up with something brilliant. Or, in my case, something that'll work…"
"@ Bob Wohl : Pressure in pipes
As a rough rule, for a straight length of single pipe, the pressure required to push water through a pipe is directly proportional to the length of pipe. i.e. if you double the length of pipe you will…"
Ahhh - the perils of the solar water heater. I had the same idea as you and did exactly as you've done, with, not surprisingly, exactly the same results.
I finally came to the conclusion that it's not a good idea to try…"
"@Kim re pH
Reverse Osmosis (RO) water is a no-no for AP in my opinion, mostly due to the amount of water it wastes in the filtering process.
I can't talk to rainwater, but I'd give it a try if I had it.
Phoenix system water has a high pH,…"
"@ Bayy Quest
I buy my tilapia feed from The Western Ranchman (click here). They stock or will order in the Star Milling product lines. Last time I was there they had tilapia feed in stock. The time before I had to order it in.…"
Thanks for the info. You are very correct regarding surface area. Given that there is only so much sun heat per square foot, the more area, the greater heating. You have significantly more area than what I have, which would…"
"@Jim : Those are impressive solar heating results.
What volume of water do you have and what are you using as a solar heater?
I don't get much more than 5F over a whole day with about 600 gallons in the system using my DIY panel: see here"
"@Kim. I use red lava rock as the media in my grow beds. It's cheap, lighter than most other rock, and very porous. The only down side is that it's a bit sharp and hard on the hands, but I haven't found that to be a…"
"@Kim. I monitor and adjust pH regularly but not often, probably every couple of weeks. I aim for 6.8 but it'll be between 6.5 and 8 depending on how vigilant I've been. I use muriatic (pool) acid and add it to the top up…"
I live in Phoenix and trying to plan a tour of aquaponics people's systems, if you would be interested in seeing what others are doing in our area and/or would like to show off your own system please send me an email at email@example.com and put AP TOUR in the subject line.
