My tank has been established now for about 3 years. I do a water changes now and again and have never had real problems with my parameters. However, recently I noticed my fish were dying off here and there, I put it down to age and forgot about it. However, lately both my gourami and BN died, so I replaced them yesterday. Today my new fish are gasping for breath and acting strange. I decided to clean out the tank again, which I did yesterday but pruned a few plants and that's when I noticed my anubias nana, and coffefolia roots were rotten to the core, they must have been like this for months. I took them out cleaned them up and noticed a smell coming off them. I tested my water and that's when it all hit home, my nitrates were 160ppm. That's after a 20% water change yesterday and again today. I've now done a 50% water change and I was wondering how long should I wait before I do it again? It's 15 gallon and it's not overstocked, just moderately planted.
EDIT: After waiting 50 mins I re- tested the water and Nitrates were 40ppm. I decided to do another 20% water change. I've also put my filter media into a better flowing filter, which could be the reason why my plants were so rotten in the first place.
Thanks
