SUMP too big?

I have a 75 gallon tank right now with a 20 gallon sump. I found a flawless 75 galling tank in local paper for 40$. Since my sump now is Jerry rigged and packed full I was wondering if getting this 75 gallon tank, having a pro turn it into a sump and putting it in my basement. Is big too much or just better?

I know pushing my water from the basement will require a lot bigger return pump. So I was also thinking with this new sump I could buy a HUGE return and later down the road buy another tank and Y off the return. ;D

Any input?

 

More water volume will only stabilize the system. I don't think it's a problem. You could also put in a bigger tank on that sump later.

 

more volume is always a good thing, just keep in mind that with more volume comes bigger skimmers, pumps, heaters, etc.

Plus it will give you more room for error, if things ever take a turn for the worse

I say go for it

 

The only limit to sump size, in my mind, is physical space and the equipment you would need.

The local marine biology lab uses the pacific ocean as their sump!

 

I have considered something like this... you'll want to consider the expense - heating/ cooling the extra water, the extra evaporation so more top-off required, larger water changes required, etc.

 

Right now I have a protein skimmer rated for 120 gallons of water. My Phosban is rated for 150. I have 2 heaters. My return pump and overflow box is what I'm worried about. I might buy a bigger overflow box for the tank now and put the old in the 60 gallon hex I want to get for my bedroom. Do you guys suggest on buying 2 separate pumps or a big pump and do all the plumbing?

With this new sump I'll be able to just cover the whole top of it and leave the skimmer all the way inside so I might actually have less evaporation bc how packed my sump is now I have no top and that's where i think most of it's coming from.
