    Chempak & Dosing Calculator

    Thanks Darrel, much appreciated looks like I need 4.5g for my 180L tank. Just for my own education, as above, "if our fertiliser has 20,000 ppm of Fe. If we take 1g of "Chempak sequestered iron" and add it to 1 litre of water, we've divided 20,000/1000, so we have 20 ppm Fe" ..... why do we...

    Chempak & Dosing Calculator

    Hi Zeus, thanks for the reply. If it is just a matter of being at the higher end of a recommended range that's fine. I was just curious as to why for KNO3 it was so different. Many Thanks, David

    Chempak & Dosing Calculator

    Hi Darrel, Thank you for that, I thought I was having a senior moment:). Could you help me with what follows the RED line. If my tank is 180 litres then the above would read if it should be 200ppm. We want 0.5 ppm, which is equivalent to 1g in 400 litres (200/0.5 = 400). I have a 180 litre...

    Darrel thanks very much for this. Spot on, that's what is happening to mine. If I get some of <"Chempak Sequestered Iron"> you mentioned do I need to add Potassium as well, I have Seachem Flourish Potassium and should I also add Magnesium, I have APF MgSO4. Or should I not add all 3 at 1 go...

    Growth and algae problems

    Sorry missed the question on Limnobium laevigatum . The numbers are declining and reducing in size, they have really thinned out. If I increase the TNC complete dosing to 40ml/week they stage a comeback. But that is twice what I should be dosing.... so I am not sure I should do that on a...
