  Could you send the web-site addresses or pics to the heater configs by Bob Taylor and the Mineral Springs web address, I would like to check them out.

My heaters are similar to the ones on youtube.  Except they are Bob Taylor's design - thanks again buddy.  They are 1000 watt stainless steel water heater elements in PVC pipe with circulation and a temp controller.  The controller cost is excessive. 


I have 12-IBCs in banks of 6 - all wrapped with 2" Styrofoam board.  The heaters are in the  sumps for each bank of IBCs' filter system.  The filter system is identical to the one that Mineral Springs Tilapia has on its website - thanks again Greg.  Greg uses bucket heater – about $50.00 – in his sump


I use the same heater set up for my 6-1200 gallon grow out tanks, except I use 2-of them in each tank.  My electrical cost is under control because in addition to being a Washington registered /licensed aqua farmer, the electric company gives me a HUGE electrical rate discount because of being a licensed/registered Aqua Farm.


As for Tilapia eating heaters, I have not seen that yet, but my big male T. Hornorums will devour about anything that falls in the tanks.  They love their grasshopper and red worm treats.

kl-contact me off group, I have a few videos and info on how to make your own heaters.  It is not at all difficult.

We live in North Texas, zone 8. Our system is in a metal hoop greenhouse. Right now, it is not covered in plastic and it is still pretty warm here.

There are !5 goldfish about 3" long in a standard size IBC, 8 blue half barrels, hydroton media beds, with okra, wax beans, kale, chard, lettuce, and a few other small plants. Our system is up and running, on an automatic timer 15 minutes flood, 30 minutes drain. 

We would like to put a submersible heater in the IBC this winter. Building one is really outside of my level of expertise, so purchase is the option here. Am I shopping for a pond heater ? Any advice is much appreciated.

Well I'm super excited to find this site as a newby. I've had cichlids for a few years and also have 3,600 sq ft of double poly greenhouse. It's providential to finally find their marriage in aquaponics! I'm trying to design a large (ambitious) system of about 2200 sq ft of media beds (1000') & DWC (1,200'). I have a pool business and I'm considering what things I can cross over - liner, pump, nat gas heater etc. it looks like about 2000 gallons of tank water and just over 16,000 gal of water in the beds. I'm in southwestern Ontario and it seems that for the most part I can keep the greenhouses fairly warm over winter but is pool heater (gas) overkill? The hot summer temps have been intense, is a chiller of some sort recommended? If so, can anyone suggest something for this size/volume? :D
