okay, so i have prefilters and on most tanks i just remove them and wash them when i clean the filter ... it's a real pain
i've been running with just shrimp till now or betta and the prefilters were nice and clean (thanks to mr/mrs shrimp) now i have fish too (and no shrimp in one tank)
here's my questions:
1) when i turn off my filter a bunch of stuff falls off the prefilter and even more falls off when i remove the hob from the tank .. there must be someway to clean the prefilter without making a mess
2) how often should i be cleaning the prefilter?
3) in the tank below the prefitler is helping hold the moss wall in place (well now it is) ideas on cleaning this one?
What i've done in the past was use a ziplock bag, zip it closed around and then pull off the prefilter, catching the stuff in the bag.
hope that helps!
What I do, is use some clear 3/4" tubing to siphon off the bulk of the crud from the pre-filter right in the tank first, before turning off the filter, removing the pre-filter, and giving it a good wringing out to fully clean it up. Gets most of the outer coating of waste off, so there's little left to float off into your water column when you remove the pre-filter.
