Nitrate reduction...

[loonz]

Hi, we have all come to understand that wool and floss in a canister filter is going to be a nitrate factory over time. I am using an Eheim and there are 2 compartments for media in which I put Chemipure and Polyfilters. These products mentioned that filter floss should be placed before the inlet water reaches them so that only water passes through the media. So how goes?

Is it okay to not use any filter floss at all when using these products in a canister?Thanks for any input.

i stuff a sponge at the pipe leading to the inlet of the filter to pre-filter out the large debitres......then the focus is to clean that pre-filter sponge regularly...

Hmmm... never knew that filter wool will be a nitrate factory... been using filter wool all the while with my Eheim 2222. normally will stuff both my chemipure and rowaphos between a layer of filter wool so that the detritus is trapped before it enters the chemical filters, seems to work fine for me. Think its ok lah, jus change the wool regularly. I change mine monthly or so.

Yup just change it regularly.. although I wonder if this would result in ammonia and nitrite production.. which is worse than nitrates... coz the foam being "void" of bacteria will not be able to break down the food particles as such ammonia and nitrite come in... not sure leh... for me the foam is there to trap bubbles

OK...i gathered that if I don't change it at least monthly...nitrate could be a problem arising from it....
