[proaquatics]

I use dryed oak leaves and the rotting aint that bad -they just disapear leaving the (ehm) stems (?). And that prosess takes a coupple of months. I collect a bag each fall and that keeps me covered the hole year.

One side effeckt is that they might make the wather brownish and they lower the Ph to around 6.3 -6.5

oak leaves really?? what fish do you keep?
