Any ideas? Just got started with my tank about a little over a month ago and have never seen this little guy before. Sorry about the crappy photo quality. Thanks in advance for any help....
AQTCJAK...Got the bubble algae part It's a major pain!!! I've been trying to get it out a little at a time without breaking them, but I don't want to tear my whole aquascape down.
Yup sponge's aren't bad. They will actually help filter excess nutrients from your tank. As your nutrient levels drop you may notice the sponges disappear.
