Hydro Pre-Filters are preferred when the need to prevent large particle waste, fish fry , invertebrates, plant leaves and other undesirables from getting inside and clogging the main filtration system.
Hydro Pre-Filters reduce the need to clean the main filter!
Hydro uses a high-grade sponge and solid construction that fits securely onto the filter intake tube. It also serves as a biological back up system if the main filter needs to be shut down and can be used with most powerheads to cycle a new aquarium immediately when transferred from an established aquarium. The Hydro Pre-Filter is aesthetically pleasing and is easy to clean.
