Filter sock poll

[d0ughb0y]

BTW, I think the Poll itself is not exactly valid, as each tank is different so the change interval for one may not apply to another. Just change as needed. I think someone mentions they change once their sock is about to overflow. I think this is the extreme. When I change, I can see the water level inside the sock is maybe 1 inch above the sump water level, still a lot of room before it overflows.

also, I think the mesh size of the sock matters. I used to wash socks before, and I use 100 micron socks, and I know I get crap buildup in my sump after a while. So perhaps the felt fabric I use is way finer, maybe 50 microns or less since I do not see any build up in the sump like before.

I don't use them. I think the sump design can accommodate what they do w/o needing them. Look at Life Reef systems which I consider to be the gold standard. None of the designs use filter socks.

The solids are collected in the socks and removing them every week or so prevents them from accumulating elsewhere in the system in the form of detritus. Thus keeping a cleaner system and sump. Most of the particulate waste doesn't break down.

People are concerned the solid wastes are hanging around in the sock for a week or so, but not if they are scattered around in nooks and crannies for an indefinite amount of time.

Regarding letting CUC consume the waste. This reminds me of a post by someone comparing how snails clean the glass of algae vs manually cleaned by magnet cleaner. You can imagine what the glass looks like, cleaned by magnet = really clean, cleaned by snails = lots of snail trails on glass with algae. You cannot rely on CUC to comsume 100% of the particulate wastes.

I dont use socks anymore. High flow will break things down faster, socks get clogged from the bacteria growing in them, i use a settling chamber. Things stay in more of a whole form there, you can see snail poop still look likd snail poop after a week and i vacuum the sump each week.
