Is there a way ?

If this is for a planted tank, what's wrong with readily available potassium nitrate ? Usually a planted tank needs more potassium than nitrate, so you use KNO3 to supply as much nitrate as needed and add more KCl to get the K up to target. -- George |

I add some KH2PO4 and my K is nearly at 60 ppm. Perhaps, shall I reduce TMG and Profito supplies but how be sure that traces are sufficient ? Thanks again ! Philippe |

Philippe Usually we need very little KH2PO4 (potassium phosphate), maybe enough to get 1ppm phosphate. The K that we get along with the phosphate is less than the K that comes along with the nitrate in potassium nitrate. After dosing those two we still need to add many times more K to get up to what the plants want. I don't know what TMG or Profito contains, but I thought TMG was only traces. K is usually considered a nutrient and is supplied in much larger amounts than the traces. The simplest method that I have seen for ensuring proper amounts of nutrients and traces is the Barr method, usually called "EI" for Estimative Index.

Is there a way ? Philippe Yes NH4NO3 ? Philippe who has fishes What for do you need nitrates ? For the plants ? Yes ! Philippe I add Kno3 to water change and I reach with this method 20 ppm of no3 and 12 ppm of K. I want to have 200 ppm of K and the 8 ppm I reach adding Kcl(can add k2so4 but I use ro water ) I dont add more Kno3 in week because K can cumulate. If 20 ppm to fresh water dont pass and in the end of week I have 0 ppm of no3 I add more fish. With this method I hold correct target of K (20ppm). If You want add nitrates daily or in every other day add NH4NO3 but do not measure and check no3 but Nh4. He is more dangerous, but plants teke nh4 faster and without any loss of energy. -- Pozdrawiam Konarski Andrzej gg 6422573 " Akwarium bez roślin jest niczym ogród bez kwiatów " -- |
