I have been dosing Metricide Plus 30 at 1 ml per day in my mini-m for a week no. My two plants seem fine.
They root easily but slowly from rhizome cuttings for me. I glue the cuttings onto small stones.
They seem like hardy plants, but are slow. I am having a problem with diatoms in my tank and have to use a paintbrush to clean the rhizomes, and I have to rub the diatoms off gently with my fingers every now and then.
It's a new tank. Though. I have had the plants for about two months and they have multiplied and made six new buds that wil become plants (between my cutting I made from each, and on their own.)
