Those of you that have a gl*******s 1500 gph overflow (or have any input to add), is there any reason to put ball valves on the 2 1.5" overflows? I'd rather not if I dont have to but I'd rather know some pros and cons before plumbing. I have a 75 gal dt, 29 gal sump and mag 9.5 return. Thanks!
over easter i am thinking about upgrading my tank to a 200 gallon that is 3 ft tall 5 ft wide and 2 ft deep
at my dads work he has a pile of 1500 watt MH lights can i use one on this tank or is it to much heat and light to wory about
