He goes on to say, “For most aquarium filter systems one dual density pad is all that is necessary as long as it is thick, made for underwater use, and durable enough to be rinsed and reused several times.”
Laurren Schmoyer owned a large aquarium store and aquarium service company for over 25 years. He was frustrated by most filter pads as they are manufactured specifically for the air filtration industry. They are untested and stuffed in aquarium filters, a combination which produces inconsistent filtering. The pads lack durability and are not thoroughly tested for all types of aquatic animals.
Schmoyer decided to create his own aquarium safe pad which beat his expectations - and his customers now rave about it!
