Water cooling using aquaponics tank

Not off topic at all, that's actually very relevant- and fresh live fish deliveries to restaurants in Colorado would likely generate quite a bit of interest!

I'm trying to build more of a healthy diet for myself and replacing beef and pork with fish figures prominently in that goal.

Anyone have recipes for tilapia bacon? :bigjoint:
They dont make a good bacon substitute but i heard fillets could be ground up and made to be a substitute for ground beef. Best part about selling the fish live is that tilapia are easy and quick to kill. Literally stick them in a bucket of ice and they die almost instantly. Quick and painless for them.

I'm not sure how many of the laws are federal, and how many might be state controlled. I did learn some interesting things from that visit to the commercial basil grower. He did not cut his basil, just rinsed off the roots and sold the plants whole, that way he was selling a living "plant" and not "food" -- even though it was sold through grocery stores. Doing that put him in a category with very little regulation. I don't remember the details, but there was something similar with the fish, like if you could find a restaurant that would buy them live (transported in tanks, I assume), then most of the regulations are side-stepped because the laws deal with "food handling and processing". If its alive, its not food yet, still just a fish. (Sorry, that's probably veering off topic...)
I think its all within the same topic. That does sound like a good way to skip any regulations.

I don't like Tilapia, if farm trout were like stream or lake trout that's a few years down the road from being stocked that would be good. Are there any less fishey fish that would do well?
Wouldn't dilution 10ml sample 100ml ro water get you back in range of your test kit?
Nothing replaces bacon, unless of course pigs can swim?

Where did you have tilapia from? Also how was it cooked and filleted? If the mud vein isnt cut out and skin removed completely before cooked then it is pretty fishy taste. Without it the fish is very mild. I dont like fishy taste much. Possibly where you got the fish from could make the difference. Aquacultered or aquaponics tilapia taste way better than even most fish market tilapia. The tilapia need to be purged of food for 2-3days before you eat them. Thats another important thing to note for the tilapia.
Blue gill, catfish, perch, and trout are other fish options but they all have specific requirements for temp, ph, quality of water, hardiness of water. For example trout require cold water of 55-60°f so those will work in colder climates but not in warmer ones.

The math would be a little harder doing that but 10ml of test water and 90ml of ro water would multiply the results by a factor of 10. I'll dilute the test water starting at half and half and go from there.

From the frozen food isle!:hump:
My poor communication skills coming to light. I didn't like talpia from the frozen food isle because of the texture. I over cook salmon for most peoples taste but not to point of being dry and even will throw a smoked salmon filet on the grill - top with butter and brown sugar before and it is (i hate to say it) almost like bacon.

You "flush" your fish :hug:

Is that because they are swimming around in the toilet all day every day? Seriously though, why or are tilapia unique in this way? I can see getting their stomachs empty (not like wild caught where that's the bait), but wouldn't they eat any biology in the tank? or is there nothing and the picastiamus (think thats what I saw in a previous pic) keeps anything from developing?

I continually forget the real way to get a 1:10 sln. Its like asking me in a parking lot with 20 numbered spots how many spots are between spots 4 and 13? Is it 9 or 10, do you count spot 4? I just use my fingers and hope I don't have to take my shoes off.

Yea flushing. Its really the only way i can word it lol. Their system needs to be clear. Its more than bowels, their body reacts to not having food for a couple days by removing any excess fat and it really improves the taste of the fish. Im sure there is more at work than i know but it definitely does make a huge difference.
I like over cooking to where there are crisp edges to the fish fillet. Butter and lemon juice and garlic salt.

I figured its what you meant lol. We all do it sometimes. I kept making mistakes when i had my first setup using a step up converter. I would blow it when i switched from current testing to voltage testing on my multimeter without moving the lead back to the voltage plug...it happens when you try to rush things and not think through.

Ok so i was finally getting around to testing the cobs output, power consumption, temp readings, etc. Has anyone compared their results to citiled table? I have the gen 5 80cri 1212 4000k cobs and they are not giving the same figures as what is in the table with the case temp, current, voltage, and lumens i am measuring. I am running the 3 cobs in parallel at 38.5v. current bounces a tad at 5.99-6.05amps and my case temp is 81.9°f. so wattage is at the high end 77.64w and low 76.87w. table says at that temp i should have 6.36amps total at that voltage and temp. I also am getting higher lumens than stated as well..18% higher around 13,400lumens. either im off on everything or their table is not fully tested across the board for their cobs and they are just following a curve based on results they ran for a couple temps and wattages. I know they dont bin their cobs, maybe i have a better batch? Or i guess im just being nitpicky. It is nice to have tables to compare to though.

I think it's nice that you're getting both more watts and better efficiency out of the chips by keeping them 50 degrees F cooler than air cooled chips... And then heating your fishtank with the 'waste' heat to boot.

That's a killer app, right there.

I was thrown off at first because i was only measuring the power consumption from the wall for the power supply so far and i was getting 350w of usage across the killawatt meter. Something still isnt adding up. Maybe i need to double check the multimeter and killawatt meter with known values and make sure everything is working ok..if they are then my power supply is getting horrible efficiency.

Hmmmm that power is going somewhere. If the power supply were so inefficient it would burn up.

Yea, 100watts has to be going somewhere. The fan on it is on constantly. But the fan cant be using more than 10-15w. Even then the losses still are higher than they should be. I'll double check everything later today and find out whats going on.

Had wife plug in killawatt and send a pic.download_20170420_081908.jpgStill high. Lights went on at 7am. About 100w of power lost on power supply. Idk which is worse, bad meter or bad power supply cause they both cost about the same. Maybe she can do a test on the killawatt while im at work lol.

Double checked multimeter using batteries and smart charger showing amps and voltage. It matches when checking amps and voltage so i know cob power consumption is correct. Also ran microwave at full power 1350w and killawatt showed a couple watts over but that should be expected. Also used 75w bulbs on a lamp one then 2 on to see if both wattages match and sure enough it is good on those too. Unfortunately this only leaves the power supply as the culprit...not good. And its the meanwell brand one too lol. Actually im more surprised that the power supply hasnt burnt up yet. Thats pretty high although now that i think about it a lot of old cheap computer power supplies were horrendous with efficiency and would blow 100-200w of power.

I'm wondering if you're running that driver at half of its rated output or less? Could have something to do with it.

Its rated at 350watts. I'll run the cobs a bit higher and see how much the power supply goes up. Its using about 2/3 rated power. Technically that should be the efficiency sweet spot. But this isnt the first issue i had with it. First the 10k potentiometer broke on it and it was stuck at max voltage, so i stuck a single turn 10k pot in there to get my adjustable voltage back on it. Now its chewing power for no reason. I may just have bad luck with this one.
