You can use Seachem equilibrium or a diy/commercial GH booster.
If you have a hard tap supply (you can get water hardness figures from your water company) ~90% RO 10% tap should be fine.Or just cut your RO with an amount of tap water, depending on your local water hardness.
hi guys!!i make all my water changes from 100% ro water i would like to know how can i maintain a gh around 5 and a kh 2?i have some plants that require really soft water like tonina belem witch i love
thanks my friend but i cant make the adjustment with tap water...i bought today tds meterHi all,You can almost certainly just cut your RO with some tap water. Have you got a TDS meter?
i`m afraid to use diy ferts and powders..i have read the articles here, i just dont feel confident enough to do it.i use all these that i have in the photo.i used equilibrium and sodaEasy
For 100l RO
6 grams NaHCO3(bicarbonate soda) = Kh-2
13 grams CaS04*1/2H20 (calcium sulphate) =Gh-5.021
hi guys sorry but i must ask again i use equilibrium but i would like to use ca and mg can you please tell me the portions at 50 litre of water for example?
The magnesium sulphate will be the heptahydrate (.7H2O) because it picks up water from the atmosphere until it is fully hydrated.You should be able to pick these up off the internet but you need to be certain of the water content.........calcium chloride dihydrate
