Sorry to hear that KittyKat. How are the water parameters, I would do big pwc
. Maybe you are over feeding? What are you feeding them?
I have DW that has been in my tank for well over a year, and most of it was soaking for 4-6 months before that in my pond and in a bucket.
I think I will have to move the fish and do complete clean of the substrate and big filter, just to make sure to get a fresh start but didn't want to shock the fish with the 1 point + pH change. I was hoping to get it leveled out by now, as previously mentioned
This week I am working 7 days in a row and have extended family arriving next weekend, so that 1/2 day to all day project wasn't really in the plans! Since it is a 72G tank, I can't reach in there too well and it will be a big chore! I think I will save half of the tank water to add back in to see if that will equalize the pH to help avoid the shock. And maybe just wait a couple more days for that since the heat treatment is half over.
