Safe t sorb and nitrates
Does safe t sorb help raise nitrate levels in the tank , my water constantly test at 40 ppm even after water changes and filter cleaning, I have a planted 40 breeder at 50% fish capacity neons, minnows and snails. It did effect the ph at first but I have that under control. I change 25% water or more every week. Everything else is just fine and the fish show no I'll signs I figure my Otto's would be the first to let me know and they are doing great. I've just run out of ideas to get it to lower and don't want to use chems .
