Such Thing As Running To Big Of A Skimmer?

It will be a heavly stock angel tank so no corals, just 2 dozen large angelfish

Any inverts? Over-skimming tends to remove a lot of iodine which can effect them. If it's just fish, definitely no issue I'm aware of.

I dont plan on having any inverts at this point in time, infact the plan was to keep the tank near osmotic.
But we all know how things change LOL

I think what most skimmers indicate they are rated for in gallons is for a lower bioload. My SWC 120 is rated for 120 gallons @ low bioload and 55 gallons @ high bioload.

That leads me to believe that a heavily stocked 190 should have a skimmer that is rated for 380-400 gallons.

I do believe it is possible to over-skim. I'm doing it right now, and my softies were becoming increasingly unhappy. They're now in a different tank and are very happy (with the exception of my Xenia, which may just be too far gone).

I don't believe you can overskim. Iodine would be depleted in all our systems, regardless OD skimmer size.

Perhaps, this just from experience personally knowing someone running an exceptionally large skimmer on an invert system and having high mortality issues. Dosing iodine seemed to fix the issue short term and removing the skimmer completely fixed it long term.
I definitely also had over-skimming issues before as well, there's probably a thread on it somewhere.

So if your saying having a skimmer rated for double system volume is bad for anything but FO why does everyone do it? The skimmer I have right now is double rated and I never had any issues with a SPS tank
