When designing the new Poly Reactor, ViaAqua’s marketing department took it upon themselves to see how many times they could use “reactor” in the title. Sadly they used it one to many times. While noticing this is a multimedia reactor which uses acrylic in the construction a reverse water flow design eliminates water channeling through the filter media thus efficiently utilizing filtering media. The reactor can be used in sump or as a hang on back model which is a unique twist to what is common in reactor land. Comes complete with fittings and pump and will be able to handle a tank up to 200 gallons, a boost of 125 gallons over the smaller PR20 model that is being currently offered. This newer model should be arriving in the coming months to local and online retailers for under $110.
