Diatom Bloom

Yep, that looks about right! I would keep your regular water changes. Are you using RO/DI water?

 

Yes, since I started about 2 months ago.

 

Yes, continue your routine

 

My advice is do regular changes, meaning no more than the regular percentage, I just recently set up a new fowlr and had my diatom blood, nearly at the end of it and I used tap water (lake michigan aint that bad). I noticed a huge difference when I started sugar dosing and using seachem stability, but either way, its a normal thing and means your rite on track, and like others said, just ride it out, you may even end up with a replacement algae but like our motto here goes, go slow, o and by the way, the only other thing I did when my cycle was over is order a CUC from reefcleaners.com and buy some hermit crabs at the lfs and they are cleaning it all up well, and make sure to have a good skimmer. Good Luck
