What do you do to get the plankton to bloom again?
I'm havinv all the same broblems but have not tried the cutrine yet. We had a freeze then hot then freeze again then plankton bloom then the FA started dieing in the deep parts not it stinks and has black muck. It's a new pond buil last fall and was very clear up until may?
Thanks for the help.
U have the cutrine but have not used it yet. Worried about my freshly stock baby fish.
