Plumming a 200 gallon

[SaltEpidemic]

Looking into possibly getting a larger peninsula style tank, they're willing to give me a good price after someone had canceled on it.

Was trying to get suggestions of how they might plum it, and what type of flow rates the bulkhead sizes would be... thank you in advance.

The first thing I would look at is the hole sizes in the overflow box.
I think the 2" holes would be for a 1 1/4" bulkhead.
And I think the 2 3/4" holes are for either 1 3/4" or 2". It will depend on the bulkhead you use. So you'll want to get that all figured out first.

Then, figure out what drain system you want to use. I would make 1 of the big holes a siphon by putting a gate valve under it, and the other big one a trickle. The remaining smaller holes could be 2 returns or a return and an extra emergency drain. This would give you a Herbie type drain system, sort of.

For a 200 gallon, I would shoot for about 1000 gph through the sump. So pick your return pump or pair of pumps based on that. I might pick a pair of Eheim 1262s, 1 through each hole, but there are lots of opinions on which pump to use.
