Angelo Posted January 19, 2015 Report Share Posted January 19, 2015 So I just purchased a drop checker from trademe for my planted tank. Just wanted to ask if theres anyone who has a bottle (250ml) or so of spare 4dkh solution? I know I can make my own solution from distilled water+baking soda but the recipe would be too much for my needs. Will be happy to pay for postage..
