    I've looked everywhere and can't figure this out. Best way to drill large diameter holes for acrylic? These would be 1.5" holes for bulkheads for my overflow. I keep seeing: "pilot hole, then increase in size stepping up to the next largest" as being standard practice. But that doesn't...

    So looking through threads, I see how people drill the tank, for filtration I'm taking it? For my 125 I was just planning on a hob overflow into the sump, but I'm curious as to how this whole drilling works? Would it be better to drill than to run an hob?

    Hey guys, going to drill my tank over Thanksgiving break and I just had acouple questions. 1) Can my overflow be to big? The flow into the 40g tank is 260gp and I'm looking at drilling 2 1inch drains (main/backup). I would think it could only drain as fast as my return pump can pump the water...

    Hey guys, I just picked up a 40 gallon breeder and a 20 gallon for my first reef tank/sump and had a couple questions. Is the Eheim 1250 (320GPH) a sufficient return pump for a 40? Can anyone who has/used this pump verify how quiet it is? This set up is going in my bedroom so a quiet pump is...

    Hi All, I am very close to getting my 55g tank drilled. Following the helpful advice of someone on the forums, I purchased a 750gph overflow from Glass-Holes.com. The 750gph model has a 1.5" bulkhead. I have a couple questions related to this. 1) What size should my return be? Should it...

    Im looking into a 10 - 15 sump tank under my 29 gallon which currently just runs some live rock and a HOB fliter.

    I wanted to take my 12G Nanocube delux, drill it from the rear compartment to make an overflow to set up a refugium. I am doing this because of a downgrade from my 55G and essentially wanted to make a "highlight" tank of all of my best corals. Question 1: Is it possible to drill the rear...

    Okay so I was planning on buying a 40 gallon breeder for a sump on my new 75g. But I am such a novice, it's not even funny..Anyway, how should I go about doing this? According to Marineland (my tank brand), the standard tanks only have tempered glass on the bottom. How big should the holes be...
