What some dont know, in a newer tank, use of NoPox can triggers blooms but mainly . . . . . When there is a sudden increase in the number of bacterial colonies that builds and becomes suspended in the water and grows at a fast rate, it becomes more visible causing the water to become milky and hazy in appearance due to an increase in nutrients especially with nitrates and phosphates, so check those two. Can also be poor filtration, not movement, overfeeding and even your water source especially if RODI filters are nearing end of useful life.
A few months, since at least January 30th. I’m dosing:
I’ve let the tank sit with no light for more than a week. It’s been running its course for sure… gets worse and worse. I’ve considered the uv sterilizer but black outs have worked for me in the past. This nano is really giving me issues.
This is an algae bloom and that window is your main culprit. The UV rays will penetrate shades-blinds-curtains. The film algae itself is likely caused by Bright white intensity and a few suspects listed below. This will take a few days to defeat as the filter being a box is insufficient to entrap the spores and bloom itself.
usually I use premixed water for water changes, top offs with distilled. I used API phosphate kit. I’m also a high school student and keep my light off and shades closed. My school has a marine lab and the window shades aren’t usually closed, yet the nano tanks there are crystal clear. I did do a large cleaning in the tank after I lost a few sexy shrimp and shook up the sand quite a bit. I think that may have been the original source because this never happened until last week.
Next time test the premixed water and I suggest taking a water sample to a store that does NOT use API kits and see what readings they come up with. If you used tap water for that water change, that would do it as well as LFS water having some content. Distilled is low in ph as the water is steamed. Believe me, as the sun is higher and bright longer, UV rays will cause algae problems
I have Zoas, Xenia, acan, palys, and a trumpet.
