So to ensure I don't do anything utterly stupid. Posted what I found from a google search below. I also saw several articles from other fourms saying similar.
Just to be clear, I wasn't planning to use the skimmer on one of my existing tanks with fish.
However The 40gallon Tank I have gotten to replace my current main tank biocube32. The 40 gallon actually includes a sump (one of the main reasons I wanted a different tank over the biocube32 for better filtration over the biocube32. ) it my hopes that will allow me to finally get Po4 lower than .8 and with luck help sps color up more in addtion to adding better lighting.
The 40gallon doesn't have a skimmer currently. The frag tank has a curve 5 skimmer.
I also have a Eshopps S-150 protein skimmer that I used in the stock tank.
I also have a redsea rsk 300 skimmer. That I originally thought that one would be large enough for the 210gallon tank. After research I found out that both of those options would be way undersized for a 210gallon gallon tank. Unless I possibly used both at the same time?
Not sure if that would work or be pretty dumb? Still looking out for a larger skimmer.
I mentioned that to say I wouldn't consider using the eshopps one same as I wouldn't risk using the curve 5 skimmer from frag tank, on the 40gallon cube.
Would the redsea rsk 300 skimmer be too crazy over powered for a 50gallon system?

Based on this search it seems safest not to use the skimmers from either of these tanks.
So any recommendations on a skimmer I should consider to be on the look out for?
I want something that's at least decent hopefully used, but not opposed to a brand new one. I'm not inclined to spend a few hundred bucks on one either.
So open to leads on a used one, a new one at decent price.
I figured if i leave the ones in affected systems alone for several weeks no fish etc like i intend with the tanks themselves they should be safe to use again at some point in time?
