how much heat does a Poseidon PS4 External Pump make? will i need a chiller to run this pump? i had a lg 4 but it was loud and i need a replacement would this pump be a good choice? i do have 2 175 mh on the tank with 4 vhos- im not running the mh to long. would this work for me ? or would i have to much heat?
