I figured it was diatoms at first but it formed a huge slimey layer all over. I've kept my lights on hoping stuff would grow in my liverock (I got some grass on one!) but I've now switched to just having actinic on for a bit. Mostly lights off.
My tests show 0 nitries, between 0 and 10 nitrAtes, max buffer, and 8.4ph.
I don't have an ammonia testing kit yet. I think my cycle is complete though.
I was under the impression I shouldn't do water changes until my tank is done cycling which I'm assuming it's almost done. My system is probably overfiltered --> super skimmer 220 and fluval Fx5 for 400gal tanks.
ANOTHER PROBLEM!! MIGHT BE RELATED
So, I thought my super skimmer 220 was causing tons of microbubbles in my tank. As it turns out, my Fluval FX5 filter is spewing out TONS and TONS of microbubbles. If I turn it off, they dissipate but after it's been on for a few hours, the tank is filled again. What could possibly cause a filter to do this? Could it be the diatoms/cyano
