Overflow question/thoughts-Glass Holes

[mr86mister]

Yeah, plenty of people with experience will drill your tank for you. They do it and have fun while doing it. They drove 30 mins to drill my tank last summer.

how can you edit GLASS HOLES?

Just to get back to drilling with water in-tank real quick.... I was in the exact same boat as you with regards to this. I didn't want to change my aquascape because I really liked it, and I was very tempted to drain half and drill.... After thinking about how much time and money I dumped into that glass box, I went with a new aquarium of the same dimensions. First attempt at drilling it and it split right down the back. It was at that moment that I was extremely relieved that I went that route, otherwise I would have had about 8 seconds to view my tank before the glass busted and water/corals flew everywhere. I know people have done it with water in tank before, just some food for thought though.

P.S. My aquascape is better than ever!

Like anything, there's always risk with whatever I decide to do. I have a few weeks till graduation so it gives me time to way the pros/cons before making the final decision.

Who knows, maybe I'll get a job somewhere that I'd have to move and drain the tank for relocation and my problem with draining/not draining will be solved haha.

Thanks again everyone for your thoughts/input so far! It's appreciated.

i work for a LFS and we install them all the time ,at least two per week . they are easy to install . they are easy to maintain for the most part but they have one shortfall as something as simple as a snail can get them clogged or at least impede the flow so it can potentially overflow . i just began making "tops" for them in an attempt to stop this from happening . now it is virtually impossible to get then clogged and i even have built the tops over sized so the light doesn't hit the box thus eliminating algae on the box and that cant clog it anymore . i thing the major problem with such a unit is that people usually get a pump that is near 100% of their flow and that is simply not a good idea for such an overflow . with the top on them they are pretty much bulletproof from snails etc but if they are rated at 700 gph its best to run them at 500ish . they are much quieter and don't have such a risk of overflowing .don't take me wrong as they are pretty well thought out except for the upper opening and a simple cap takes care of that .also it is very easy to drill with water in the tank as you only have to lower the level by about three inches . seven minutes is all it takes from start to finish and that's not hurrying at all .

I just drilled my new sump. It's not that bad to do, though it is intimidating!

Looks like it came out pretty good. Keep me posted on what you think of it as you get it up and running.
