Hi all, Over the last few hours my 455 litre tank is gradually developing cloudiness.
Water parameters are:
Nitrite 0
Ammonia 0
Nitrate 20 ppm
The above 3 are as usual. However, the ph is vastly different to usual now reading around 7.9. Normally, after a day of co2 would normally read 6.8 and 7.6 before lights on. Temperature 24.7 fairly normal.
The tank has been running for 12 weeks so I assumed cycled.
There have been a few changes, maybe this could be an answer. Here goes :
1) co2 canister ran out this afternoon, drop checker still reads 20 though
2)Due to lockdown can't replace co2 so have raise height of lights by a small 20 mm
3) When doing water change 3 days ago, scrubbed two pieces of bogwood in hot water because of Bba
4) Although I dose weekly with Ferropol and daily with Ferrapol Npk macronutrient, I have started adding Ferropol 24 daily. Fish seem fine. Any suggestions would be gratefully received as this is a real head scratcher for me. Thanks in advance. Nigel. Ps Will be reducing dosing right down, now I'm no longer co2 injecting
