Bruno Posted September 2, 2014 Report Share Posted September 2, 2014 Thinking about switching over from HOB to canister, and the clean up the look of the tank, going with a in line heater. I was looking at the Hydor since I don't know who else makes them, but the largest one (300w) says it is for 50 to 80 G tanks. I have a 90, so how big of a deal breaker is that? And will flow rate matter at all in that? I like to over filter so if I get a larger canister - rated for 150G for example, am I adding more trouble? Any other heaters out there I should be looking at instead? Quote Link to comment Share on other sites More sharing options...
jvision Posted September 2, 2014 Report Share Posted September 2, 2014 I ran a 300W on a 120 for years and it was great. It ran thru an Ehiem 2217 and had an extra 2215 on the tank, too. Quote Link to comment Share on other sites More sharing options...
zoopkamol Posted September 2, 2014 Report Share Posted September 2, 2014 I run a 200w on a 75 temperature goes +- 1 degree. Have set for 81 temp low is 80 high might hit 81.5. 300w on a 90 will work np. Could get away with a 200w I bet with little temperature fluctuations. My 200w on a 2315.

Awesome - I was considering a 2217 as well Quote Link to comment Share on other sites More sharing options...
flyfisher Posted September 3, 2014 Report Share Posted September 3, 2014 I run 2 x 2217 on my 75g with the 300w Hydor connected to one, temp stays at a constant 78f no problem. Quote Link to comment Share on other sites More sharing options...
Frogfish Posted September 3, 2014 Report Share Posted September 3, 2014 My Hydor crapped out in less then a year on a 65gal tank so I went back to a submersible type. Look at what the other guys are doing with dual filters, if your filter dies so does your heat. If I ever find my receipt and replace the inline I will strongly consider adding a secondary filter as a precaution. Quote Link to comment Share on other sites More sharing options...
Blue Ram Posted September 10, 2014 Report Share Posted September 10, 2014 I too had a brand new inline Hydor stop working after 6 months but I also have had one on another tank running for years. Go figure? Sure a pain in the butt when they stop working because you have to replace it before you can take it apart from the filter.

Hi_Im_Ian Posted September 11, 2014 Report Share Posted September 11, 2014 I got 2 Eheim 2215s and 2 200W Hydor inlines on my 75 and they seem to be doing the trick, I read that the heaters failed sometimes and I decided that I would keep 2 smaller ones on the tank so that if one got caught in the on position my tank wouldnt be fried. I haven't really noticed a reduced flow either, so there's that. As for going bigger with the canisters, I would. The flow is a huge limiting factor, it doesn't penetrate the surface well so a bunch of the biofilm is currently reigning supreme, but I'm going to get an aquaclear surface skimmer to fix that. Good luck! Quote Link to comment Share on other sites More sharing options...
Bruno Posted September 22, 2014 Author Report Share Posted September 22, 2014 Thanks for the replies - I will give the Hydor a shot Quote Link to comment Share on other sites More sharing options...
