I have never had issues with Prime. Best product from Seachem if you ask me. I sometimes do 90% water changes on some tanks, add tap water and prime and all is good.I switched to Seachem Prime for my last 3 water changes and am noticing a change in my Anacharis. They seem to have stopped growing all together and are starting to melt back very slowly. Before I had to cut them back every two weeks, they grew like weeds! I got three other bunches out of them! Nothing has changed in my tank other than the addition of Prime. Has anyone else seen this? Just wondering. They were responding very, very well to EI dosing till I used Prime.
Maybe I'll switch back to Tetra Aquasafe and ditch the Prime.
I have never grown Anacharis either... Aren't they cold water plants?
