my filter (fluval u3) has a seperate compartment for putting zeolights in .
I have however found mixed reveiws to them and was woundering if i could use this space in my filter for other media
the genral idea is they start to leeach chems back into the water after some time and unless i want to keep buying more i would be better to take them out . ditto the carbon pads in my filter . would i be better to stop buying new ones every few months and just fill the filter with sponge or other media
