i just got my first case of ich in about a year
i got ich guard and am currently treating. i am treating as recommended by the bottle.
this is about 4th day of treatment, and signs are slowing but not stopping.
it is a 55 gal comm tank with swordtails, guppies, mollies, and chory.
i guess my concern is why i got the case of ich.
i did a water change, about 25% and the local shop says that is probably why i got it.
i question is, i try to match the water temp outta the faucet as best i can.
the shop says the water has to be almost exactly the same temp during the change.
any advice on how to do this or general advice on how to do the water change?
thanks alot all
