Which RO skimmer?

[GothFishKeeper]

I’m gonna be upgrading my skimmer from an Eshopps S-120 to either the reef octopus classic 110SSS space saver, or the reef octopus classic 150SSS space saver. But I don’t know which. I have a 90g DT with a 20g long sump and a 29g refugium. For livestock I have a pair of skunk clowns, a pair of pygmy wasps, a dragon goby, a WTB tang, and a watanabei angel. I also feed my corals and nems meaty foods 1-2 times a week. Would the 150SSS decrease nutrients too much? NO3 has been 5-10ppm and PO4 has been 0.15-0.20 for a while now. I plan on eventually trying to add just one acro so I want nutrients much lower than that of course but I don’t want them to bottom out.

This is the tank:

the 150 is ~24 inches tall, the 110 just under 20.


If it fits, I would get the larger skimmer and if it's pulling to much, put it on a timer.

Oh yeah i’ll definitely fit. Thoughts on a used one though? A guy near me is selling one on FB marketplace for half the price of a new one, but it’s 8 years old. I know good pumps like the ones on RO skimmers last a long time but 8 years quite a while. If it’ll last me another few years though I don’t mind replacing the pump itself later on

Are you interested in selling your Eshopps? I need one part of it, and not the motor.

When you put a skimmer on a timer does that effect the ATO?

The fluctuations in water level will affect the salinity slightly but in most cases I would not be concerned with it.
