I'm confused about cyno and diatoms. I have both.
I'm in the process of turning a 37 gal FOWLR in to a reef. It has been set up for 4 yrs with only 1 pajama fish and 4 nasarius snails. I've recently put in new lights, 2 actinic and 2 T5s. 2 weeks ago I added 4 peppermint shrimp, which are doing a number on the aptasia, and 15 small blue knee hermits. I now have cyno and diatoms.
My water parameters are: Ph 8.0, ammonia 0, nitrates 0, Alk norm, phos 0. I've been keeping the actinic light on for 10hrs and T5s for 6. Yesterday I turned them off since the room it is in gets plenty of natural daylight, no direct sunlight. I've been doing weekly 20% water changes with distilled r/o for 3 weeks and I only feed every 2 or 3 days.
I know I disturbed the sand bed trying to vacuum the cyno. From what I understand when you do this is may release the silicas from the sand and then you get diatoms. Is this correct? If you disturb the sand bed why would you want animals (nassarius snail) to stir it up? Am I doing everything right and just need to be patient?
Thanks for any advice,
Jill
