Koralia and heat

jcato · #1 09/17/2007, 08:18 AM

i recently added 2 #4 koralia's to my 75g and have noticed about a 3 degree increase in water temp. is this common or do i have a defective pump?

simply put - you added a motor to your water - the heat will rise, adjust your tstat on your heater down to compensate

dont have a heater and i have run MANY powerheads that dont add any noticable heat to the system. at 8.5 watts i would think something else is wrong.

Its normal, I added a Koralia 1 to my 29g nano and the temp went up 2 degrees. I live in South Texas and do not even use a heater.

That does not sound normal to me.

Does someone know if it is normal for those pump to be that hot.

BUY THE NEW VORTEC -- BUT FOR 300+ THATS A LOT OF COIN FOR A POWER HEAD

i just added 2 koralia 2's on top of my 3 mj1200, eheime 1250 return submerged, and css 125 in sump in my 50g and temp stays at a constant 78 deg. with just a fan blowing when halides are on.

but to answer your question, mine did not heat up the tank at all

any updates on this issue? I am considering these for my tank but dont want to deal with 3 degree temp increase.

I added a K-2 to my 29G tank and temp rose 3+ degrees. Not too happy with that. I had to add a fan to my sump area to drop the temp back down. I am going t e-mail the manufacturer and see what they say.

2 #3s on my 75 no heat issues

i just added a 3 to my 40. I will let you guys know if there is any diffrence in heat.

IMO any PH will add heat. Whether you notice or not is another story. The vortech is ok but make sure no one touches the motor that sits on the outside...............talk about hot! It seems like you could fry an egg on one of those suckers.
