help to newbie about overflow

[Myka]

Since the tank is already filled, I would just skip the sump. Buy a Deltec skimmer (the only HOB skimmer that's decent IMO) if you want a good skimmer. I know a couple people who have drained their tanks halfway and drilled the back panes. I wouldn't do it, but they didn't have any troubles. That's a thought if you're brave (or crazy).

If you don't want to drill, as already suggested by fishytime, get a Lifereef. I've tried quite a few times to make mine fail, but it has always prevailed!

Before you drill...make sure it is not tempered or this will happen:

I use an overflow....never had or have had any problems...no flooding...they are self priming if the power goes off......I have used them for more than 15 years....different ones..imo....it is easy to upgrade your tank...or downgrade and you never have to have a drilled tank....right now I have one on a 72 bowfront.....just buy a larger pumo than what the rating is...that stops bubbles getting caught in the syphon tube.....even if bubbles build up..the flow does not stop...just slows up a bit...
The last one I bought was from blue world when Mike still had the store...but I am very positive Ken could get you one
