Whilst "experimenting" with my new 100 gallon setup, I thought I'd try adding plenty of Osmocote plus directly to the tank floor, then topping it with my fluorite. By "plenty" I mean probably 60-70% coverage of the total floor area, but never more than 1 grain deep. Lighting, CO2, EI ferts all good, I've got quite a bit of experience in that department now. No algae issues etc. I've noticed a couple of things though that I haven't seen before. Vallisneria is not generating roots at all. A lot of leaf dieback. H.Wisteria, B.Caroliniana, lower leaves turning grey. Is it possible that I have made the substrate too rich?
If I have, I suspected there is no easy fix for this....?
I was under the impression that the Osmocote Plus is not too strong and being slow release sitting on the tank floor it wouldn't cause any issues. But now I'm not so sure....
