Big Al's is always my number one choice for aquarium equipment and supplies. Brandon and the staff are extremely knowledgeable and always take the time to answer my many questions. They know me by name and someone is always there to greet me at the door. This is a store that really backs their products. I've purchased a lot of equipment at Big Al's, and on occasion have had a product fail within the warranty period. Big Al's has always replaced or given me credit for the product with no questions asked. I've shopped around most of the aquarium shops around Calgary, but Big Al's for me, is always my top choice.
