I neglected my aquarium for 3 weeks now other than feeding and topping off water and basic things and finally have the time and energy to get back to the schedule on cleaning and maintenance, and noticed a few changes - my main concern is a orange or yellow sponge (I'm color blind so i can't ID it ) that is growing IN my powerhead. My powerhead was designed poorly and has lots of areas for algae to get caught and now a sponge too. I'm just worried if i try removing with a toothpick it'll spread around the tank and nuke it. I added a picture below but I'd like some advice on removal without breaking my equipment. Current plan is to take the power head out and put it in a 5g bucket and just clean it out and then rinse it. Could someone ID the sponge for me? Its only growing at the powerhead probably because of high aeration levels. Tank is 1.5 ish years old. Thanks
