Roots are always dissolving causing plant to come afloat, I use lead weight to hold them down, I just read on an something I searched up on google it says they are easily killed by jamming into gravel or by the lead weights.
I used to just put them down on gravel without any lead weights but still had to jam them down and they've always grown very well, what's wrong now? I find that with many fishes without any weights they won't stay down, but with weights they start dying.
What are some alternate way to hold them down and prevent them from dying?
Thanks a lot
