Are there any downsides to adding GSH to a BG/LMB pond? I have algae growing in this pond pretty bad since the beaver ate up so many waterlilies. I though that I might wait for the lilies to respread, but perhaps GSH might work sooner. I have GSH in my YP/SMB pond that I could try and catch and use as stockers. My worry is that they might compete effectively with the BG.
