Iím stumped. In the last three days, Iíve had a green slimy algae attack on my plants. It has nearly encased one of my floating plants. The only changes in the last 8 days since the water change are:
1. I added a sponge prefilter over my intake valve on a Fluval 50 HOB
because I bought some trapdoor snails. The outflow is set to its highest output.
2. I reduced the red LED
on my Fluval from around 45% to 10%.
3. I live on the Ohio River several hundred miles downstream from the New Palestine train derailment. My local water company did not say they altered chemicals in our water because of it.
My readings 5 days ago were ammonia 0, nitrite 0, and nitrate 10. All the fish are fine, but Iím losing my mind. Itís a 29 gallon tank thatís been up for five years. Iíve got 50 years in the hobby and Iím at a loss.
