Actually its not the atmosphere that causes the temp to increase, its because I placed a 500 gal
/hr powerhead that causes this, the temp of our tap water is 83 degreeF, as maxis-jet is too expensive if I were to buy the same strength. I bought this 500 gal
/hr powerhead at the lower price than maxis-jet 600, and yet the strength is stronger, but it creates heat, haiz. I think I should buy either a cooling fan or consider changing to maxis-jet. BTW
what number of maxis-jet should I get in order to get ethe same strength as this powerhead? And does maxis-jet really doesn't creates heat?
