The DCS models look too bulky for my sump, plus the next model up from the 150 is only rated to 200g. The Skimz one is rated up to 300g and is cheaper I believe. Can't remember tho, ive looked at so many skimmers over the past 2 days lol
I don't get why people think it's a good idea to get a skimmer that's over rated for their system. The skimmer is just going to sit there and do nothing until a fish farts. Is your total system even close to 533g? I'm pretty sure you have a 75g sump so assuming it's filled with 55g of operational water, you are just barely reaching 200g not counting for water displacement by rocks and sand. I wouldn't get a skimmer that's rated anything above 300g for your system and even that is too much.
No I actually have a 40g sump. And the reason behind going bigger is BIOLOAD. I plan on stocking this tank pretty well.
Also, another factor is when I wanna upgrade again in a few years, I'll be able to reuse this skimmer assuming I don't get something that's bigger than the skimmer lol
Also. Skimmer ratings are subjective. The Manufacturer rates the skimmers and I NEVER see what they are actually basing that rating on. Heck... My Tunze 9002 is Rated for a 54Gallon tank. Yeah maybe a 54 gallon tank with a chromis and few zoanthids. Not my heavy 54 gal sps tank with hundreds of zoo's and softies.
Well I only plan on doing 3 tangs. Plus I'm gonna have 4 wrasses, possibly 2 triggers and a bunch of other lil guys.
