I purchased a number of things at this Petsmart for my aquarium setup. The prices are a little high, but not exorbitant. The only big thing I wish they had is Bio-Spira or a comparable product.
My complaint that unfortunately rules out all the cons is about the live plant tanks, which are all connected. I used their plants in my betta tank, and in a few weeks not only were there hundreds of tiny snails in the filter, but large leeches began to emerge. When I mentioned this in the store, the employee said they had had some problems with leeches in the tank before and had not bothered to redo the tank. The leeches attacked my fish, leaving numerous visible wounds and scars that remained his entire life. The staff in general were not very knowledgeable about fish or live plants. They might be good for mammals, but not for fish!
Pros: lots of tank accessories
Cons: leeches/snails in plant tanks, unknowledgeable staff
