They have a small back corner dedicated to salt.
Neat selection of fish, but I sure as heck wouldn't go out of my way to ever go back there. They do have sliding doors as you enter though if I recall. Ha ha ha ha.
Make sure you hit 16 Kennedy road SOUTH. It used to say north on their website, luckily the street that splits north / south is within a block. I had a hell of a time finding it the first time I went.
Corals were seriously lacking. They have a small island in the middle of the salt area with corals in it. Nothing spectacular.
That is one thing I find with all of the big al's stores, corals usually are not that great, but fish selection isn't bad. That is to be expected though. Big Al's is a huge chain, they need to move volume, and volume is going to be more of the bread and butter items and leave the crazier, more specialized corals and fish to the specialty stores. I bet over 50% of their customers are moms and dads buying their kids crappy little guppies, or other easy (and cheap) fresh water fish with small to medium tanks. (50 gallons and under)
) we are a small operating that's 15-20mins away from the Dundas strip.
