OK pretty much you need Potassium Nitrate,Potassium Phosphate, and trace right, if i go with the seachem ones, which is a cheaper way i guess, which one should i buy? flourish trace, flourish potassium, flourish phosphorus?
It is WAY cheaper to buy them as dry powders, the smallest 250gmm packs will last years in most aquariums, the SeaChem range will last much less, months maybe, and they are more expensive to buy too!
www.aquaessentials.co.uk sells the powders in the UK.
