Craigs list lucky find 150G and all accessories

$$$ ?

How much should i expect to pay to drill 2 holes in glass. If it's less thank $100 i'd say packleader has a solid answer to my concerns. Then it's just a question of what to use to bulkhead the holes i'm not using.

I just learned somthing new today. The LFS said bigger tanks do not need water changes as often because with more water build up takes longer. They told me once every 2 weeks would be sufficiant and once a month after the tanks been going with live rock for a year or so. Does anyone know different?

 

Drilling tanks isn't too expensive usually. I will ask my guy at the glass shop what it would normally cost. Off the top of my head I would say $10-$20 bucks a hole? Maybe even less?

The water changes would more depend on the actual system. There are plenty of small tanks that don't do any water changes at all My normal schedule is every 2 weeks or so on my 40, but I have gone a month before. And that's mostly for the trace elements.

 

As far as sump goes underneath it depends on what you wanna do with the tank. I have a 150 and I put a 40g sump/fuge under mine. I would have gone bigger but I wanted to have extra room for a chiller and auto top off res too. Also the only way I could fit a 55 or 75 or bigger sump would be to cut a hole in the side and slide it in. So most people say the biggest that you can fit. I agree. I did have a seperate sump and fuge and went to one unit and I like it better...

 

I would use the two middle holes in the bottom as part of a closed loop system. Get rid of the center overflows. See if the glass is tempered and drill more holes in the back and the corner, put in a corner overflow box and set up a closed loop on that tank. For that price, I think you did well.
