Hi All, (last night)
ok, I have an established, heavily planted 4' tank. 27 fish (now!)
Fed every other day with frozen brine shrimp or dap. (frozen) algae wafers, and pellets for cories. (Did feed live brine shrimp last week, first time for months)
Cleaned for their usual routine 50% water change a week ago. Today I have come home from day out, 4 dead fish! Nothing on any of them, or on any in tank.
All stats at zero, (amonia, nitrite, PH 8, but always at that)but nitrate, out of tap it's 10/20, but in tank it's 40, just taken 50% out and ready to replace, any ideas please? The only difference at mo is temp has increased to about 27 from 24, that's all I can think of. Nothing else has changed.
Don't really want to dose yet, I have 2 loaches, so have to be careful of dosing. Ferts are just TPN+ couple times a week. Use to dry fert, but haven't been doing so for about a year now.
Next morning- water still same, 50% change, trate reading 40, now I'm afraid that I can't tell you what it was last, as lke you, if tank's ok I don't test, but it's the omly thing I could think may be causing the deaths yesterday? All fish ok this am, but I am out for the day till 9pm, so I can't answer any questions till late.
One thing I remembered last night was that I had a layer of thick algae on back of the tank that this water changea week ago I decided to clean off, do you think maybe some is decaying in tank that i missed syphoning out? Should I try that tonight? Any ideas gratefully received.
Can't think of anything else to tell you, coinincidence of 4 older fish dying?? Seems too much to me, but nothing on any fish??
Many thanks, am around for another 20 mins after that I'll check back tonight. Using API test kit.
