Cheapest way to buy
What is there to say. They clean the water as well as any HOB cartridge filter. Way cheaper then buying them pre-assembled.

I've been using this product since 1970 with good results. I always top-off the charcoal with API's Ammocarb for more complete filtration.
I have used these filters for 3 years with no problems. They are easy to put together & cheaper than pre-assembled.

the prices are super great, and you always seem to have a sale going on for them. great buy
