Test Kit for Liquid Fertilizer
I am considering buying the pfertz fertilizers because of the discount it is offering this month. However I am very new to planted tanks. My 55g has 5 plants: 2 anachris, 1 java fern, 1 red ludwigia, and 1 frilly plant. I have Flourish root tabs installed, and my substrate is mounds of pea gravel around the base of the plants, with play sand poured lightly on top and play sand in all other areas of the tank. Lighting are 2 18W fluorescent. The tank just finished cycling within the past couple of days (ammonia=0, nitrite=0, nitrate=7).
Will using the liquid fertilizers mess up the cycling of my new tank? Do I need to use a test kit to monitor the levels of phosphorus, potassium, and nitrogen, and if so where can I get the test kit?
