Hello everyone, I just need some advice. Pretty sure I have a bacterial bloom on my hands. It started sometime in March, when my first betta passed. I took him out the day he died and the tank slowly became cloudy, I had a snail in there, a nerite. It cleared up a little and during that time I added a new betta and another nerite. I had this system with my first betta and it worked wonderfully. I don't know what the issue is now. I did water changes for a while like...everyday but then realized that was bad. I have not done a water change in about a week and a half. 20gal long, two nerite snails and a betta, lots of small java ferns, I dose liquid CO2 everyday and ferts once a week, both API brands (CO2 Booster and LeafZone). Also have been seeding a new, bigger sponge for my filter for about a month. Parameters were last checked today: Nitrite-0 Ammonia-0ish (hard to tell) Nitrate-5-10 Should I keep waiting or do a partial water change on Sunday (my usual water change day)?
