Hi Everyone, I was inspired to make the stainless steel immersion tubes found in the following thread: https://skfaquatics.com/forum/topic/9455-cooling-multiple-tanks/ I made mine with the following materials - x metres of annealed seamless stainless steel tube grade 316. Outer Diameter 12.7mm, Wall Thickness 0.9mm, ASTM 269. I got mine from Midway Metals in Sydney for $5 per metre. - A hand bender, rated to bend thin walled stainless steel. Got one from ebay for $99. - A tube cutter, again make sure it will cut thin wall stainless steel. I got mine from ebay for $32. For 60cm tanks I recommend 3 metres of tubing For 30cm tanks I recommend 2 metres of tubing Your hand bender will have an inherent bend radius, using this you can calculate the length of tube that you will use up with each bend whether it be 90 degrees or 180 degrees and pretty much how much tube you will need depending on your design. NOTES: I used 12.7mm tubing as you can then squeeze 12/16mm aquarium hosing on to it snugly (if you are paranoid use hose clamps as well). I also used 12.7mm OD tubing as its the maximum diameter you can get a hand bender for that is rated to bend stainless steel. Do not get thicker than 1.0mm walled stainless steel it will be a nightmare to bend. Make sure your stainless steel is annealed seamless tube this is specifically made for severe manipulation. This is for freshwater application only... the guys at midway said this would last 3 months in a saltwater tank lol. Good hand benders are each made for one specific diameter only, make sure you get the right one for your tube diameter. I am happy to post links to the ebay items if I'm allowed to. I'm pairing this with an Eheim 2213 and a Resun cl 200 chiller to chill 2 x 60cm tanks and ultimately 3 x 60cm, I'll update once this is done and give some feedback on the temp differences. I hope the info is useful.
