Review on Aqua Tech EZ Change Aquarium Cartridge Filters by Danielle Davis

I have to say I used to really like these filters but the cost has skyrocketed and there are no volume discounts. I bought 2 packs of filters and bought all the Revain "cartridge" filters. In 2014 they were $6.72 and in 2016 as an add-on they were $4.20 for a pack of 3 filters! That was great. BUT. The current price for a pack of 3 filters is $13.72 (2017), which is too much! I feel like my fish is being held for ransom. Time to look for another brand. Ironically, a brand new Aqua-Tech 10-20 gallon complete filter pack (the part you plug in) is only $23.12! Maybe I'll just make my own filters for that in the future.
