I can't drill my tank because the nice people at Perfecto put one of those sticker on my tank bottom under the glass with silcon over it. The "

o Not Drill" or "

rill All You Want". I don't know because they smashed the sticker into a little ball before sealing it

So I need a HOB overflow. I priced the CPR overflow and about fell over. $100 for a overflow give me a break! So I started to look for DIY ideas. I saw the $15 PVC overflow from Reef Central. It works but it is a lot of tubing in the tank and kinda of wierd looking. Almost built it anyway but I think I found a design I like better anyway. I found on a Nanao reef forum It looks pretty haus but I might scale it up anyway. It is a much more normal looking design and my Lowe's carries grey PVC so it should look cool. I am going to start builting it next weekend so check back if your interested
