Algae on filter? Mold on heater?

My tank has been cycled for a week now, running for over 2 months total.

Upgraded lights a couple weeks ago and started dosing with flourish excel yesterday.

Today I noticed the my filter his this greenish brown growth and some white fuzzy stuff on the suction cups on my heater.

Any idea what it could be? I tried to clean off the suction cups and now I have little white debris floating around the tank

Should I clean off the filter also or will the flourish excel eventually clear that up?

 

The algae on filter, if doesn't bother you don't have to take it of. I can't really see the mold on suction cups.

 

I remove mine from the tank for weekly maintenance and use a soft bristled toothbrush to wipe them clean in a bucket of clean dechlorinated water.

Generally you don't want to wipe algae off of tank ornaments/hardware while they're still in the tank. The algae will only resettle on another surface.

 

the growth on the suction cup will fade in time its very common

 

I got that white fuzzy growth on my suction cups too, it will go away soon it doesn't pose a risk to your fish

 

Thanks guys, what a relief. In other news... Had an ick outbreak. Totally unrelated I assume
