Just picked up my new 80g tank. Never had to use a sump before so I was wondering what my max gph should be? Im going with an Eheim so would it be better to go with a 1250 (317gph) or do a 1260 (635gph) with a ball valve in between?
Ive heard that you want a lower gph for your return to let the skimmer work right? The tank will have mostly LPS and fish.
Hopefully in a few days Ill get my new tank which is an 80 gallon cube. Ive been doing some research on in sump skimmers but really cant come to a conclusion. So I figured I'd ask for some input on what I've narrowed it down to. By the way I'm figuring a total water volume of no more then 120 gallons. Here's my choices:

Ive been using this stuff for about 2 months now and all was well. After my water testing today Ive found my Ca was 410 (good) but my Alk/Kh is 11.5. Ive seen this slowly rise the last 2 weeks but Im not too sure how to lower it. I currently dose 10ml of each into my 42 cube. Is it really as easy as just lowering the Alk dose and keeping the Ca dose at a normal 10ml or is there more to it? The only reason I ask is because the bottle says "add in equal doses". a full water report reads:
