I Have been running my 2 x 2080's and 2 x 2252 internal filter for a month in my 240 gallon now and I can never be happy , opted for these instead of 2 x 2262 due to space needed in stand. I am noticing gunk buildup in my hoses but not really hindering flow either in or out. is it time for me to change media, crack the 2080's open and change blue filter and white filter out? when do i change filter media every 3 months 6 months? cmon help a brother out BTW current stocking is 4 silver arowana 1 jardini 2 senegal bichirs and 2 spotted pleco (overstocked!!)
