Can i have a 10 gallon sump on a 75 gallon?

I found a great deal on a tank w/ sump package, but it has a 10 gallon sump. (it has a built in skimmer so space isn't the issue) Is that enough? thanks!

 

Why dont you spend 40 bucks and get a 20L they are much wider so you can fit all your equipment in? 10 gallons are too small to make a sump with imho especially with a 75 Dt.

 

I would be concerned about a few things. I think the sump is undersized generally speaking but it really depends what you're looking to get out of your sump. A sump can provide a large number of benefits but if you only want to take advantage of some of them that's your choice.

Depending on how it's laid out you could have microbubbles from the skimmer going back into the return pump because it might be undersized and not enough bubble traps between the skimmer and the return pump.

Make sure the sump can contain all of the backsiphoning from the plumbing when the power is off to make sure you don't get a flood in case of power loss.

Being so small the chamber that houses the return pump may be on the small side which would mean it would take a relatively short time before it runs dry without being topped off to replace evaporation. If it will run dry quickly that is more maintenance you need to be concerned about either through topping off constantly or maintaining a good, redundant, auto-topoff system.

Also, I would make sure that you can actually fit your heaters and other equipment in there so that you actually get the full benefit of having a sump.

There are probably a few other things I'm forgetting right now, I would just do some research on sumps and the benefits they provide and decide what you really want to do with your sump, what works best for you.

Here's a start for some sump info.

The Size of a sump is dependent on the equipment it needs to hold. If it is working for this system then I say go for it. I'm sure in the future you may want to upgrade a few things this might mean you need to upgrade the sump. But if this puts you into a 75G Today than it's a good thing
