After work yesterday my tank was completely clear. I left for about an hour and when I came home the tank was cloudy. It is a white tint, no color. I had tested the parameters the night before and I tested again after the water got cloudy. The night before I added Calcium and Iodine because my Ca was low at 380 and Iodine had tested low a week or so ago. I did not do a
Calcium test or Iodine test last night. I use RO/DI water for topoffs and changes.
Tank has been set up about 6 weeks and everything has been pretty stable so far.
Water parameters:
pH 8.3 (before and after)
SG 1.023 (before and after)
Ammonia 0 (before and after)
Nitrite 0 (before and after)
Nitrate 2 (before), 0 (after)
Alk 5 meq/L (before), 3 meq/L (after)
My assumption is that it is some sort of algae bloom because the nitrates dropped to 0 overnight. I am a little concerned about the drop in Alk but I attribute that to adding the calcium. Should I try to raise the Alk?
Anybody have any suggestions??? I know, I know... just be patient.
BTW, I am just getting through a substantial
diatom bloom and I am having a cleaning crew delivered today. The rocks are a really ugly rusty brown color but it seems to be getting a little bit better.
