i even get free ro di water woo hoo lol[/QUOTE

Ive been getting that free ro/di water from them too because my local fish store closed down because of the economy. But recently, ive been having hair algae outbreaks in my 55 saltwater tank. After troubleshooting, I finally tested the petco water for nitrates and just as I espected, they were at about 20ppm. So all that water that was used in water changes and top offs were feeding my system with nitrates. So id double check their water from time to time. I even asked to see their RO/DI system and they refused to show it to me, which encouraged me further to NOT use their water. I have had good success with fish from there though, all four have been living for at least 3 years now.
