Got to admit I use sponge filters in all my tanks. I buy loads at good 
prices & sell hundreds out across the world. I have noticed that in all 
these hundreds of filters the sponge composition is different. Some sponges 
really collect the muck & cleaning results in a real sludge whilst others 
are really clean. These collect little muck. I think it's a fine balance on 
sponge density which works best.
I'm presuming your Hydro sponges are comparible to our Algarde sponges.

A mystery for the grey matter. Two tanks side my side in equal full daylight 
with equal fish, plants, snails. One tank remains green & requires 90% water 
changes the other remains clear & requires little water changes.
It's a little experiment I'm doing. The only difference is one tank holds 
lyretail guppies - the other holds wild Poecilia caucana.
Which tank is causing the green water problem?
Do different sp. produce more waste products as food for algaes?
