So does this mean you're at 3lb/100 gallons? (According to carton I believe rec. dosage is 1 tbsp/5 and that is for 100 gallons and 1 lb. So if you're using 3 fold you should be at 3lbs/100.) I'de raise to 4lb/100 gallon......
You said you cut back on the salt though since nothing affected it? It's not miracle tonic, it's just salt, you need to get it up to recommended concentration and leave it there....... let it work. I usually leave salt that heavey for a week or 2........
Take my advice with a grain of salt.......LOL I'm no expert. Just telling you the actions I'de take if I was in this situation......
I wouldn't consider Melafix a med........ Isn't Pima the one for bacteria? Either way there are much better, stronger meds out there for bacteria.
You could have ordered triple sulfa and been done dosing it by now if you would have taken the advice back on pg 3.
