Nitrite spike #1
My relative overfed my malawi tank and now it's in seriously problem!!

NO2 was like 5ppm
NO3 20ppm
NH3 0

The water is very cloudy just exactly like the end of the NO2 cycle.

I did a big water change but it didn't bring down NO2 much, the test still show strong purple color. My plan at the moment is to do daily water change for 2 days and see how things will turn out. Any suggestion?

Getting some matured media from other tanks are impossible. My community tank is too densely planted and under-stocked for all readings are 0. Same goes for my betta tank and no way I'll risk taking any media from shrimp tank

Re: Nitrite spike #2
Hi nathan.

the filter is playing catch up then with the nitrite being the after result of an ammonia spike missed.

A 50% water change will lower nitrite to 2.5ppm so I'd be tempted to do 2 largish changes am and pm. This will be needed for a while until your nitrite is reading nil again.

Do the fish look OK, no gasping or anything? try to increase your airation is you can too.

Re: Nitrite spike #3
The fish look pretty okay but I think it's the fish that's hardy. Aeration is already very high in the tank

I can't do water change twice a day, I won't have enough hard water to do it twice a day. But I will try to do it daily
