I'm sorry this sucks to hear and is why I don't test constantly for nutrients. I just keep an eye in the tank and test if somebody looks unhappy or off.My favorites. Lost all 7 in a hunt for lower phosphates. Should have listed to Danger Dave's repeated advice.
Adjust based on the looks of the tank, not parameters...
Dumb dumb dumb.....shouldn't have chased. Now that those are gone. I will continue a slow and steady attempt at lower phosphates now.
Good luck with the Jawbreaker.
