[APD] RE: Help raising GH from 0!
There is a recipe for synthetic water at uniquaria.com/articles/swr. The
recipe calls for Sodium Bicarbonate but you could leave that out. It also uses
Potassium Bicarbonate but this could be substituted with some other Potassium
source like Potassium Chloride which is what Mortin's "Salt Substitute" is made
of. Aquatic Eco Systems sells Calcium Chloride in 4 and 35 pound containers
at a reasonable price. It's more soluble than Calcium Carbonate. You can get
Calcium Sulphate from homebrew suppliers. I found it for $1.95 a pound at
daveshombrew.com. The Mallinckrodt chemical catalog lists Calcium Sulphate at
$95.75 for 500 grams! I know you might be concerned about the chlorides, but
the author of the synthetic water recipe says his plants are doing well.
Did some research and found that Dolomite is actually Calcium Magnesium
Carbonate! So, due to the carbonates, this will raise my KH as well...Also, being
the smart person I am, I have decided to read the ingredients inmore detail now
(instead of at the pharmacy) and find that the tablets have lactose and corn
starch in them too. So, any ideas on: - How much will this raise my KH? same
amount as GH? - The effect of lactose and corn starch on plants/fish? - I
thought I had found a way to add Calcium and Magnesium without raising KH. Anyone
know of another way?
