I had my tank water perfect with the ph balance and nitrates and all that stuff and I go and buy 3 fish from Petco and it throws my nitrates so far off that they are reading off the charts! I am PISSED beyond repair!! I have spent so much time and energy in the past 3 weeks to get this water right only to have their friggen water make my tank nasty again!!!
DO NOT BUY THEIR FISH AND EXPECT YOURS TO LIVE AFTER YOU DUMP THEIRS IN YOUR TANK!
That is all, thanks for listening!
