I came up with an idea that works and i thought I would share it with the rest of you. I've noticed that several online suppliers are selling sponge filters that attach to the intake tube of the HOB
filters. Most of them are simply a round sponge with a hole in the center for attaching to the intake and there a very few suppliers that sell them with the hole only on one end (which is better).
I came up with the idea of getting a small sponge paint roller from Lowe's or Home Depot. These little rollers are closed on one end, as you probably know. (see link above)
I carefully removed the sponge from the center roller hub (this takes patience).
After that I rinsed the sponge well in cycled aquarium water and installed it on the intake tube of my HOB
, I could already see the improvement in the water clarity.
NOTE: I recommend that you get the rollers at one of the big box stores like Lowe's or H.D. rather than the Dollar Store because they are better made and will not fall to pieces when you remove the sponge from the center hub.
TRY IT...IT WORKS !!!
