Has anyone ever had this issue?
I just bought 5 beautifull roseline sharks. I set up my 10 ga qt tank filled with my ro water, set airstone, matched ph and put them in. they were happy swimming around, i put in 12 drops of aquarisol and i put in 5ml of api ammolock. Immideatly they started not swimming right, so i started doing a water change and they were getting worse, my wife in desperation suggested putting them in our sump, but by that time, (within 10 mins) they were dying.
Ive never had a reaction like this before.
