I used to add magnesium when I dosed dry ferts. No idea the Gh,KH or content of my water except being in a rural area it will be high in P and N. George says his water is hard and I am in the same region so I expect I have hard water too.
I downloaded the Nutricalc thingymjig and have got a little green fish looking thing as an icon on my desktop. If I click on it it opens up a table Great so far, but what are you supposed to do next and what figures are we supposed to be making a note of :?
I typed in the figure 150 and clicked on the litres check button. This is based on the fact that my Juwel Trigon 190 holds 190 litres and I deducted 40 litres displaced by the substrate and the rocks etc. So 150 litres it is. Do I only have to then click on calculate or something and read off the figures?? :?
What is the ID box for? And the Description box? Whats the notes bit for at the bottom? Why is Thursday written in bold? Errr anyone got an idiots guide for this, don't mean to cause offence to whoever designed the table just need some help to understand it better :?
Sorry there are so many questions but any advice will be very welcome.
Hi John I have just bought a tub of Epsom Salts from the chemist - 100% MGSO4. Re the above half a teaspoon twice a week, how many litres does your tank hold and how much would I need to add for 150 litres? :?
