[Algae?]

This is my 29 GAL so SAEs are too big for the tanks. I got an otocinclus catfish and like 4 corys. I got 2 SAEs in my 55 GAL though and no black beard algae there.

I got some black fuzzy thing growing on my plants, the wood stump, and also on the sponge filter and was wondering what it is? Some kinda algae? and how do I get rid of it? I added some phosphate filter on my HOB and added some algaefix nit not really working. Any help be great. Thanks!

@ColuWill do that and see how that goes! Thanks!! 

[Discus white spots]

Parameters are ammonia 0.25, nitrite 0.25, nitrate 10. Temperature 84F P.H. 6.8. One of my discus have some white spots, is this ich? I heard Discus doesn't really get ich as the temperature in the 80s usually kills ichs. I think its ich because when I added community fish into tank without quarantine them before hands and also when I was acclimating the fish, the bag went in the tank so the water in the bag got mixed into the tank. I have a bottle of ich-x to be ready to use and just want to double check from the forum if it is ich before I apply the medication.

Thanks,
