I'm absolutely pissed right now. Since the Snadhopper Blenny died, I called and asked to see if we could get store credit. They said yes, but they required to test your water first. Knowing nothing was wrong with my water after testing it, I brought in a water sample. One of the workers told be my Nitrates were at 30!!! He said they couldn't refund anything over 10. I said that that wasn't possible, because it said 0 on mine, and he asked what test kits I used. I said API test strips. He told me my things were wrong and to get better ones. To ensure my tank wouldn't have any big issues like that, I went and bought Red Sea test kits knowing that they are better then API, meaning more accurate and reliable. As soon as I got home, I tested the tank for nitrates. And what a surprise my nitrates were at 0. I lost $21 dollars and great fish because of them. I can assure you I am NEVER going back to that place.
