Hello everyone welcome to my thread, to which hopefully I can learn a little more and successfully begin my project for my Cuttle tank. :] So far I'll start of by saying that this will not be my first go around with cuttles, although it will be my first time hatching and attempting to breed. The last Cuttle I had, I bought when he was around 1/2 an inch and still eating mysid shrimp. He died about a month or two ago, right about at a year and a month maybe. Coolest fish I ever kept, and my wife is in love with them, so now I'm turning my 55g into a Cuttle tank. My plan is to have the 55 main display, and a 10g or 20g sump underneath for my sump/nursery tank for eggs/hatchlings not ready for the main tank. I can't drill the 55 because it's tempered, so I'm going to be making Dual PVC overflows, to hopefully reach about 900-1500 GPH in the main tank, which would be about 3/4'-1' PVC I personally think that flows a little high for cuttles because I had mine in low flow but he didn't really come out to much besides to eat. Although I kept him alone. Anyways, I'm not sure what kind of output pump I should get for the sump, or lighting for down there. This will be my first sump build and I've been watching YouTube videos and reading articles up the wazoo trying to figure this out. So any advice on the would be greatly appreciated. The 55g is technically ready for the cuttles, it's been running for a while as a FOWLR and I've had no issues, has a modded AC110 into refugium, fx5 running empty just for flow, and a haggen 402 power head, with a coral life light with one 10k bulb and one antantic bulb. So I'll be trying to build the sump quickly. Ecause my wife ordered the eggs from our LFS already for 20$ I'm not sure the a mount of eggs that will come but I'll update you on that when I get them home. I have a breeder net for them already set up in the tank, not to much live rock in the tank defiantly under 20lbs so plenty of swimming room I have most of it piled up for caves for my previous fish. I'll probably have the sump done by Friday at the earliest, but any suggestions between now and then would be great. I have 2 bottles of mysid feed waiting for me at the LFS too. So I'm ready for the little buggers.
