Well i wanted more fish than just clownfish so I might be upgrading in a few months. like 2-4 months. Im going to be keeping a 55 gallon with corals and whatever I can get. I currently have a 55 gallon that is not drilled. I was thinking about getting it drilled but i dont have any tools for doing so. Im planning on drilling two holes for an overflow and a return. But I dont really know yet. How many overflow should i use? If i dont drill my tank im gooing to get a hang-on overflow rated at 600GPH. And if I do so get this how much GPH should the return pump be? Thanks. Ill get some updates when I can.

Well. R33f...

Am not much help to you here, am on a big learning curve myself with getting my new setup ready..

Keep us posted of your decision as i am always interested in other people's setup and how they do it..

Well I think Im just going to be doing a overflow box, since I dont want to pay extra for getting the tank drilled and buying PVC pipe to intall to the back. Im just going to be having a tube for overflow and a tube for the return pump.

that is exactly how i was going to do it at the start...But, have decided that i am gonna drill the tank myself, ordering a drill bit next week, and do it this way..

Niko

If you have sucess drilling it, I would like some details on how it was drilled ok. Thanks :)

of course i will let you know mate...No problem at all..

Niko

Thanks M8 :D

One overflow box should be plenty for a 55 gallon tank. You need to use a pump that matches how fast your overflow box will drain. You also need to consider head pressure when choosing a pump. Meaning how far does the pump need to push water up into the display tank. So if you used a overflow box which drains 600gph you will need a pump the produces 600gph when it reaches the display tank.

This calculator will help you figure out the head loss: http://reefcentral.com/calc/hlc.php

Well the wet/dry will be 3 foot away from the tank meaning up and down. I guess a 700GPH wont do so well. Im going to get a 800 GPH powerhead about the same cost. Thanks PB. Ill add anything else when the tank is up and running.

What kind of bit did you order? I think Mazza was considering trying to use a carbide bit, but I don't know how well that will work out.

I was going to order a bit but thinking about adding some more money for the plumbing and stuff i decided to just go with a hang on overflow. If the tank break on accident i dont have anymore money to buy a new one. So its better to just get an overflow than risking :)

How is your project going r33f-boy?

Yes, i would like to hear some updates if you have any mate..

Hi all, It's been quite awhile, but I'm glad to see everyone's tanks
and read the updates... :)

I recently tried drilling a few tanks...you can read here how it went...

It does have a happy ending.

The drill bits are Diamond core saws. You can get them off Ebay
fairly reasonable.

Great post. Good job! I really enjoyed your commentary throughout.

Nice. I will use this. :)
