Hello,
I have a 29g Oceanic Biocube and i have noticed that there is pink spot all over the acrilic. They are extremly hard to scrub off. I was wondering what these spots are.
Thanks,
Austin
Probably coraline algae....a good growth....but unwanted on the sides you look thru...LOL
Elbow grease will do it, or a scraper...just make sure you get one for acrylic
you can even use a credit card
