    K2SO4 solubility problem

    Hi, I have a quick question. Before I read the solubility notes for Potassium Sulphate I tried based on the calculator to dissolve 100.28 grams (equivalent to 5 tbsp + 0 tsp + 1/2 tsp + 1/8 tsp + 1/32 tsp ) of K2SO4 to your 500mL dosing container. As you will have guessed I now have a lot of...

    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...

    Hi, I have seen contradictory advice on this question. I now want to remove Cupramine medication from my 180L Juwel tank using a carbon filter pad which is fine. The filter turnover is 1000 litres/hour. How long should I keep the carbon filter pad in place to ensure it has removed all the...

    Plants melting and no growth - help !

    Clive, thanks for the advice, I really appreciate it. I do have floating plants on one side of the tank, spray bars cause that unfortunatley. Strangely enough that's the best performing side also. I will start with the Excel but keep the reflectors and photo periond in mind also. Many Thanks, David

    Plants melting and no growth - help !

    Clive, thanks for the advice, I read the link. Since I have already screwed up, could I ask 1 final question. Should I reduce my photoperiod now and by how much or after a month or so is it now too late and I will just have to wait for the tank to sort itself out. Thanks for help, David

    Can I stop using RO water straight away?

    Hi, When I started thinking about a heavily planted tank I read a lot of advice on the WEB (befoe joining UKAPS) and the recommendation seemed to be you needed RO water and a KH of 3 to 5. From what I read here, it seems I don't need RO water at all. So can I just go 100% tap water at the next...

    Need to increase CO2 - advice

    Not sure how to do that. Would increasing the length of time the CO2 runs not achieve the same result? I used to run it from noon to 8pm at 120 bpm but now I run the CO2 from 8am to 8pm so effectively increasing the amount of CO2 injected by 50%. I am assuming this would be the equivalent of...

    I have a heavily planted tank with a D-D CO2 system which operates at the specified 1 bar pressure maximum.

    New to EI dosing, algae questions

    Thanks for the clarification, very useful. I agree. I decided to go the EI route to at least try to ensure I have enough of the right nutrients to elimate that possibility. I can't really do much more with the lights short of a major investment so that left CO2 as the last variable. I have a D-D...

    New to EI dosing, algae questions

    Yes, it is a 180 litres empty, but I measured it as I filled it up after adding substrate and rocks etc and it contains 125 litres (approx) of water. So I based all calculations on 125 - hope this is correct.
