My Nitrate levels are extremly high (100 ppm+) and I'm looking for suggestions to get it back under control.
- 3 years+ established
- Approximately 20 fish- mixture of Tetras,Gouramis cats,plecos,angle fish
- 55 gal.
I had been in and out of town for approximately 3-4 months, needless to say the tank maintenance and water changes have suffered. The PH was low and needed to be brought back towards a 7. I decided to give the tank a good cleaning and water change, and maybe overdid it. I syphoned the gravel while doing a 30% water change. I also changed the two cartridge filters that contain carbon, and added a mixture of new carbon/zeolite crystals to the plastic sleeves in the filter.
Does it sound like I overdid it and killed off the bacteria? Any suggestions would help. I'm now doing 10% water changes twice a day to see if that helps.
The other tests (ph-ammonia-nitrites) are now ok.
