So my tank has struggled with nitrates/phosphates/ algae for years.
I don't have many fish in my Fowlr.
I just lost my Starry blenny and flamehawk last night at the same time. Both healthy and no sighs of illness, a few years old. Other tankmates include a white-tail bristletooth tang & mandarin dragonet(plus 2 urchins and some hermits)
Water test this morning PH 8.2
0 ammonia 0 nitrite, 2ppm nitrate, phos is 1.0
Salinity is .025 temp is 78
I am however am noticing more alage than normal. (including some cyano bacteria) and the thick brown goopy algae has been covering the overflow and I have to brush the slates everyday to keep the water flowing. Brown will be covering the gravel in 1 day as well. But... what would cause 2 healthy fish to drop dead overnight?
I'm possibly thinking low oxygen from maybe the overflow getting clogged literally overnight everyday? That's the only thing I can think of, I've had worse algae!
it just seems so weird for 2 healthy/hardy fish to suddenly drop dead with no spike in anything. I've had nitrates as high as 200ppms and I've worked hard getting them down but have always had high phos.
The tank is 4 Years old
I have slacked on w/c because me and my family have been sick for weeks. So I think it's been 3 weeks since a water change. But that doesn't really strike me as a reason for fish to drop dead.
