I had a sick fish and treated with microbelift artemiss/herbtana. Since then i am getting microbubbles from my skimmer
Are you still dosing the tank? Have you removed that stuff from the water yet? (activated carbon and/or water changes?) Does it mention this side-effect in the instructions?
Can I ask what happens if you use to small of a skimmer?
I had a 55 gallon mixed tank turned into a 150 gallon, and now a 220 gallon. All while using a coralife skimmer that claimes to be good up tp 125gallon. Would it be Benificial to add a 2nd skimmer now that I'm beyond what it claimes to suport? The dial is maybe 9/10ths of the way up 24/7 my nitrates seem to be around 10-15ppm.
First, there's the rule of not fixing what isn't broken. If your tank is doing well, it's doing well. Admit it. ;)
Second, aeration is one of the main benefits of protein skimming IMO...if not
the main benefit.
Third, if you like the skimmer (easy to clean, seems to work well, etc) then I can't really recommend something that's going to be significantly better.
If you want to try something different just to try something different, I'd have to suggest either a Tunze 9410 DC or 9415.
Or if you wanted to stick with a classic look, maybe shop for a used AquaC EV-series skimmer. An EV-180 or EV-240 would probably be ideal.
every time i feed it goes crazy and fills the cup with water.
Cut the air-input a little and see how it does over the next 24 hours.
If it still floods, cut the air-input a little more and see how it does over the next 24 hours.
Etc. :)
Don't make any big adjustments – only small.
And unless your adjustment floods out before the day is over, try not to make than a single adjustment per day. Of course make another small adjustment if you get a flood. ;)
Overall this is an easy way to tune in your skimmer.
Also, make sure every part and tube associated with air-intake is 100% free of calcium deposits. Inside the venturi hole where the water and air actually mix is a common place for buildup that's hard to see.
