Pre-drilled bottom, diagram/info?

[loser]

Hello all! Just got a used oceanic 75 gal tank, pre-drilled, 2 holes in the bottom of an overflow area.

I've never had a drilled tank before, is there a thread around referencing basic plumbing? And filter types? Or any websites that would come in handy?

I did a quick search but didn't see what I was looking for.

I can seal it & do freshwater, but part of me wants to dabble in saltwater. Never done it before, aside from a sand substrate brackish tank with a couple killies and a hermit crab.

Thanks in advance for any help!

You can use this for FW or SW but the plumbing is fairly simple. You can buy plumbing kits.

Couldn't find one for oceanic but I would think they are sold somewhere. Note that these kits only take you to the bottom of the tank. From there, you are on your own. I would suggest at least reaserching a non-manufactured setup like the herbie method...

This will be cheaper and quieter.

You'll need to figure out what size your holes are (guessing 1" and 0.75") and then get you supplies:

Bulkheads
PVC
PVC primer
PVC glue
PVC cutter
Union(s) optional
Gate or Ball valves (use in either the herbie drain and in the return line after the pump output either way you go).
Locline for the return line so you can adjust the direction of the return's flow. There are flare tips and jet tips so pick which one you want.


You can find a lot of supplies at HD, Lowes and Grainger but Bulk Reef Supply and Savko have everything you need.

Predrilled is to run a sump. You can't really do any other filter with it. Sumps are really easy to explain, you have tubes that reach the very surface of the water when the water overflows into the tubes it falls into a container below that has a pump in it. The pump sends the water back into the tank and essentially overflows the tank pushing the water back into the tubes and down into the container below again. It essentially increases the amount of water in your tank as well as provide a huge filter. Plus you can put your heater in the container to keep all that stuff out of your tank. Its really the way to go with a large tank.

Doh! Now I get it. I'd assumed it would be a canister setup...now everything I saw makes sense.

Thanks!
