API Tap Filter and Nitrates
Has anyone here any experience with this filter. It appears to do what it claims to do: remove stuff from water, including nitrates.
I have 4 tanks, but I am trying to deal with my 56 gallon at the moment. All tanks parameters should be very close. They aree all community tanks, except for the oscar who lives alone.
The tank is cycled, has a lot of plants. Ph runs about 7.4, ammonia is 0, nitirites are zero. Nitrates: they are high straight from the tap. Runs about 20 - 40 according to the API master test kit. (liquid). According to the instructions from API, minerals need to be added back as well as a ph buffer which I have been doing. I swear the nitrates are getting worse. That was one reason I got the tap filter was to try and knock the damn nitrates down without chemical alteration.
So, In essense, two q's.. anyone else with an API tap filter and api tap filters and nitrates.
