new sump= Major problems

[chevyjaxon]

i went to Big als and bought a new sump made by megaflow this week. cost $400.00. ok so heres the deal bought the sump to quiet things down a bit now things are pretty quiet but my temperature went way up to like 81F and thats from 78F the other problem is the amount of water evaporated each day is almost 15 litres my walls are wet because of this. this is a 90 gallon tank i have a heater that now resides in the bottom of the sump and remains unplugged i have a fan over the top of the sump but still the temperature goes as high as 79F this fix is only temporary at best as the hot season is still coming any thoughts would be appreciated

What is adding the heat that wasn't there before? Some pumps create a lot of heat. Did you add any lighting?

i do have a pump that i used on my previous sump its the biggest pump rio makes it a 32 hf in my previous sump i had no problems though

Is this sump smaller than the old one? Reduced total water volume could cause the temperature to increase

[chevyjaxon]

the new sump is about the same size as the old one it does have a bacteria chamber however and that is closed off the rest is open

There must be another reason for the heat buildup. Apart from lights and a heater the only other source is your pump. Put your hand on it to see if it's overheating.
As far as all the humidity you're getting I'm not sure what could be going on there. I regularly run my tank at 81 and the tank is behind a display wall so the room isn't that large. My total water volume is a little over 350 gallons and I don't have a problem with humidity.
I just make sure I get good airflow to the room.
