I’m in El Paso and the LFS’s are limited. I prefer Petsbarn over Petsmart. Both are off I-10 and Sunland Park exit. When I need a NitrAte test kit, I have to drive to Las Cruces to Petco to buy one.
Petco also has a better fish selection (and prices) than the EP big box pet stores.
As far as planted tank needs, I use the Internet.
