Mild fishy odor

[Jeremy257]

I recently set up my new build. I completed my cycle a couple of weeks ago and have added some fish. I have had smaller tanks in the past and have not encountered the mild fishy odor that I currently smell in the basement where the tank is. I notice it most when I open the stand. I've been changing my socks out every 3 days (with no signs of clogging prior to change).

The tank is an Aquasole 120L which is identical to the previous version of the Elos 120XL (same manufacturer) This is perhaps important and I'll get to that shortly.
Icecap 30 sump
Icecap K-160 skimmer
Return pump is an Octo Varios 6

Could I potentially eliminate this odor by running a carbon reactor?
Could this odor be caused by low flow through my sump? I didn't realize that the Varios is way too powerful for the overflow system. I have to run it on the lowest setting which may be lower than overflow max but the next setting up is too much. The overflow system can supposedly handle ~5x turnover.

I'm working to get my parameters to ideal SPS levels.

My current parameters:
Nitrate 5 ppm
Phosphate .08 ppm
Kh 9.1
Calcium 440
Magnesium 1440

Thoughts? Help?

Mild fishy odor

I have the varios pump also and ran into the same situation. I put a ball value on so I can go to the next setting to help increase flow

Edit: following along for the fish odor issue

If you wash out your skimmer cup, and turn the skimmer off for a day, does the fishy smell still exist? (also after the sump section had a chance to air out) That's the only real place any real smell would come from that I can think of.

I think that as long as the skimmer is working well ( appears its of adequate size) and the cup is cleaned regularly there shouldn't be a smell. Humidity also was smells worse so maybe a dehumidifier will help. Running carbon will also help remove organics/smell.
