I just ordered a vortech pump and I would like to tell people that might be interested in it what I think about it. I would have to say I am overall happy with it but it is not ideal. With all the maxi jet mods I had in my tank. Four over all. I am down to just one left in there now having this pump. The amazing thing is the temperature reduction in my tank. My tank is 300 gallons and in the winter it would not go below 80. Now in the summer my tank is at 78 with all the lights on. I am selling my chiller because of this pump. The only draw back is the noise. It is not silent on full blast. It is silent up to about 75% power though. If you have a small tank and can get away with not running it full blast it would be ideal. If you have a monster tank and need to crank it up expect a little noise. Also the flashing light on the controller is a little annoying but I am going to cover it up with electrical tape once I get another vortech and dial them in together.
