Hi guys,
Last week I did a remodel of my tank and figured it had been about 8 months since my last filter clean, so I got a bucket full of tank water and put my biological media into that bucket and hosed out the sponges and stuff. A week later I decided to test the water and Ammonia is about 3.0ppm nitrite and nitrate 0. Obviously signs that I've killed the bacteria in the filter.
Tank isn't terribly overstocked: 530L, a red eared slider, 5-6 minnows, a couple of danios, a few tetras and a flying fox. I only feed every 1-2 days and only as much as he eats within a few minutes. I don't appear to have lost any fish, and no tell tale signs of ammonia poisoning which is weird, fish seem happy no red or bleeding gills.
So what should I be doing? Just regular water changes until it cycles again?
Thanks in advance
Matt
