I noticed small spots before now the white is spreading. Here's a pic.
Ive read that it could mean mag is low but I've never done anything for mag and I don't have a test kit for it (ordering). One thing that has changed is one of my blue bulbs went out so I put in another white until I replace it. So now there are 3 white and 1 blue t5 could the increase in lighting bleach it?
Another thing I've been doing is dosing ca
