Hi,
I would remove the bioballs, etc. as I don't think you need it!!!I don't have any of that stuff ib my tank and I have had it running for 5years now!!! You have enough biological filtration and mechanical filtration with your protein skimmer IMO!
Did you have any mechanical filtration or chemical filtration while your tank was cycling since you didn't have your skimmer running?
Have you checked your water parameters lately? Have you performed a water change recently?
If your water parameters are fine and you have recent;y done a water change, I would say you are ready to add beginner corals.
Remember that your tank is a new tank and the maturing of the tank will take some time therefore, many types of fish, inverts and corals should be avoided til your tank has a chance to mature for the best success and health of your tank and livestock!!!!
Good luck with your tank and your coral additions!
Soft corals are a good beginner coral to start with(ie. mushrooms, zoos, leathers and star polyps)! _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.
