Drilling a 75 gallon

Hi all!

This is my first post and i'm brand new to the hobby. so new that i don't even have a tank yet! as my time and money are precious to me (i don't have an excessive amount of either) i will be researching everything heavily. So, naturally im deciding with tank selection first. its gunna be a 75G(48x17x21 i believe) and it will be drilled i want to have a 750gph overflow(10X seems like a good number). so, what i want to know is what size bulkhead i will need to attain that. is there a specific dia. to flow rate i should look at? is 750gph max a good number?(i know that my return pump will dictate actual turnover, just want to make sure the overflow will be more than capable). any input will be much appreciated! thanks

 

Welcome to 3reef.

I believe a 1.5" bulkhead is the size you will need to get to 750GPH.

 

1 ,1.5in or 2, 1in

Hello

Back in 1988 I bought a 75 gal Oceanic tank and I had the FS, which was privately own, drill the tank for me. The owner of the store drilled the tank and put in a pvc drain in the hole. Then he took a piece of glass shorter than the full height of the tank and siliconed it into the corner of the tank. He then took a 20 gallon long aquarium and made a wet/dry filter out of it. I attached a threaded joint to the drain. Then I attached a short piece of pvc pipe to the joint. Then I attached 90 degree elbow to the piece of pvc pipe, another short piece of pipe and another 90 degree elbow. The water would cascade over the piece of glass in the corner of the aquarium and drain into the 20 gallon wet/dry filter. The water would then travel through the wet dry/filter and when it got to the last compartment I had an eheim 1050 submersible pump and the pump would pump the water back into the tank. I don't remember the size of the drain or pipe, but I think it was three inches. I worked great and I never lost a single fish in the two years that I had the tank. I don't care for a drilled tank that uses a pvc pipe inside the tank to drain the water into the filter. With the piece of glass siliconed into the corner of the tank you get a surface skimmer which is wider than a round pipe. I don't remember how many gph the eheim pumped, but it work great in my application. This summer I am going to buy a 65 gallon high tank and I plan on doing the same setup that I hand in that 75. I am going to buy a wet/dry filter and hook it up and use another eheim for the return pump. I should work fine. Hope you get exactly what you want and I hope that you are happy with it and it serves you well.

Good luck
