Still awesome😉
Why are you using K and Micro from VIMI, I will also be back for N fertilization with Urea will use on a 500ml bottle 2,5gr wich gives me 0,5ppm Urea from each dose and 1.03 as NO3 where I will compliment the resting dose with KNO3
do you know http://aquarium-fertilizer.eu/ ?? Great source for getting great chelates and all of the macronutrients in dry powders
I dose Urea when lights are on for an hour. Your are right about the TDS - was thinking about one thing and typing the other. Plants can take out N from Urea directly so it is a big question how much of NH4 is left and then converted to NO2.
Some thoughts about discussion Po4 rates in Nuno and in EdwinK tanks.Main role here plays filtration.I guess EdwinK filters packed twice more biomedia than Nuno one filter.So filter catches not small amount of that 1ppm.Some people from flowgrow.de said they have done chemical analisys of filter mud so they found there large amounts of po4 and fe.Some of them doses only 0.1-0.2 ppm po4 a day, but they go with one filter and no biomedia, only sponges.Because of that EdwinK dosage works good in his tank.Only my opinion..
Don't neglect biofiltratrion in substrate, surface on the plants and are around the plant's roots. In my opinion filter plays a minor role here.
