Need Help Identifying White Algae Type Strands on Aquarium Glass

[rickynichols]

Can anyone tell me what this could be? I had some green algae on the glass with it and wiped it off with a magnet brush. The white strands came back withing a few hours.

Thanks in advance

Kind of sounds like a bacterial bloom. If so, it will likely harmlessly run it's course within a few days. Are you carbon/vodka dosing by chance?

Can you describe your tank/vitals?

I have just set up a 5"-6" deep sand bed in a 55 gallon aquarium. I have a trickle filter which I gutted and filled with live rock (all submerged) that flows into a refugium and then back to the display tank.

I put the water in, then the sand (.1mm - .5mm, 100lbs), then live sand (.5mm - 1.7mm, 40lbs)then a mix of base rock and live rock on top of that in the display tank. I waited 2 weeks then added a kit from IPSF with bristle worms, mama mia worms, nerite snails, sandbed clams, 6 left handed hermit crabs, mini brittle stars, wondermud, live sand activator and amphipods. I then added about 40 nassarius and cerith snails. I also added 2 serpent stars but they died right away, there were shipped very poorly and I dont think I had a chance with them (not ordering from them anymore).

I have blastomussa coral doing well, and my zoanthids are opening up nicely.

I also have a lawnmower blenny (just added yesterday) to help keep the algae down.

I am running a mag 7 return pump and a koralia 750 gph pump opposite each other for flow.

I am running a T5 light 4 x 54w right on top of the water. The lights are on 10 hours and then moonlights come on. I have recently starting not using the moonlights because I see no critter movement other than the snails.

Ammonia - 0.35 ppm

I use purified water with no chlorine or chloramine but not RO/DI
