    Quality products at great prices. I was very pleased with how quickly my order shipped and was received. The bags they come in are a heavy material and reseals perfectly on the first try every time. I use this in my aquariums and it mixes clear. Overall great products!

    Order arrived packaged well and on time. Ferts appear very pure and mixes well. Comes in its own resealable bag for long term storage. Pricing is very competitive.

    I can’t find fertilizer salts at any other online retailer with prices and combined shipping as competitive as here.
