Forgive me if this has been covered - I read the FAQ and am still a little fuzzy on this point...
If I've got a heater keeping my tank at a good 78-80 degrees, and I do a 50% or 100% water change... how do I acclimate my fish back to the tank so he doesn't experience shock?
Do I guess at the water temp as it comes out of the faucet and then put the thermometer in? Do I put it in the tank and keep the fish in the cup (for a 100% change) till I see that the water is all the right temp again?
And do I use the conditioner again for a 50% change?
Thank you for any advice!
