Filter Socks...

And the nitrate factory .. well my tank went from chronic nitrates at >25ppm to 1-2ppm after I started using socks so I'm not sure that's as significant as people say. So yeah, basically it comes down to "use them" or "don't use them" as per whatever one you prefer more. Thanks for the link though GSP, interesting reading.

OK, well no of course its not taking it all out in a normal system.

I think the person posting in that thread is talking about 'sps systems' which these days seems to mean ultra low nutrient systems. I should have been much more clear about this...I am talking about low to ultra low nutrient systems that rely on heavy feeding to keep corals growing. I was thinking it but of course forgot to actually type it

So...In that case, you can actually strip the water too much. I know some people who don't have many fish and are using systems like ZEO, need to overfeed just to keep color in their corals. I have a zillion fish now, feed as much as they want (enough that sheets of nori gets left uneaten now!?!) and don't register much nitrates (2 ppm) or any phosphates anymore after about a month of ZEO (no algae taking them up either). Actually more like a few months of ZEO but one month on the new tank. My corals keep their color and I assume its because I feed so much and have a lot of fish...I am by no means down to that 'Ultra low nutrient' system quite yet but my tank seems to be headed that way. My thought (and I believe the RC posters) was that at that point, filter socks can start to take too much out of the water.

Not everyone running ZEO is getting to those 'ultra low nutrient' levels though, so its not just a ZEO thing...I still see ZEO tanks with hair algae growing. So they obviously still have nutrient problems.

Anyways, that might clear what I was thinking up a little.

I agree, they aren't going to take too much 'crap' out of a regular system but when you are purposely feeding the tank, whether it be coral food, fish food, amino acids, ect. and then are using a filter sock to catch out some of that stuff, I am not so sure it makes sense. Or at least I can see where people on that side of the argument are coming from
