I have a 60 gallon tank with 2 filters and my fish just keep dying I've tested my water and been using ammo lock but even that's not helping I went from 8 fish to 2 in like a week I've done water changes and all is there anything else to do

Did you change you filter recently? Did you buy any new fish and didn't quarantine it? Anything new that wasn't sterilized before putting it in the tank?

Hey Michael - sorry to hear that! I beleive Santo is onto something - if you changed out your filter AND, depending on how much water you've been taking out, it's possible you impacted your biological filtration. You say you've used AmmoLock - is that because you determined that Ammonia was your problem? that would most certainly point to an issue with your biological filtration. I'd encourage you to give the store a call at 717-299-5691 - someone in the fish room can walk you though a much more detailed discussion on how to help your scenario. Good luck!

may one of ur fishes had something that gave it to the others and now they all r sick possible

I haven't bought any new fish they were all doing fine for days then all of a sudden just started to die I've changed filters and water I've got a full set up with 2 filters doing water changing regular I've done alot of what Petco says and it doesn't seem to be working out
