I have a 40g mixed reef that I've had going for a year, it's sumpless with a Tunze 9004 skimmer and an Aquaclear 70 that I use for carbon and phosguard. I started using the AF reef salt a few weeks ago and all was good. I then stared using the Pro Bio S and NP Pro almost 2 weeks ago. I dose one drop of each one night and then 2 drops each the next. Since I started on this I've started to get a light fluffy algae on my rocks and tank glass, does this seem like a normal process when starting with this stuff? I've since taken out the Phosguard as I read not to use alumina based phosphate removers with AF products so I don't know if that is a cause. I'm hesitant to get the coral additives until this algae disappears. Phosphate levels are 0.03 or less when tested with a Hanna Ultra Low Phosphorus checker. Alk is around 7dkh and Calcium is a bit high at 468. Any thoughts?
