  6. Sock Washing

    in Technical

    Posted

    i have been using socks for 3 years now, i find that they last in my tank approx 6 months then i have to replace as they start to get more and more particulates go through.

    as for getting them like now, you cant, as you clean them, the filtration capability diminishes.

    i also found that spraying from the outside back in is better and lets them last longer. just my observation.

    also you dont wanna pray too hard core cos that damages the sock, the sock works better also when it is a little bit dirty- traps finer particulates.

    i just take them out, spray outside then a light rought spray inside to get rid of the big chunks.

    I think so too! but he claims its a 'rare' and imported L333! if it is, ill take some, but however, the stripes resemble a choc zebra, a relatively common plec

    small too

  12. The coolest filter I've ever seen

    in Technical

    old woolen sock? I very much doubt my work socks would catch 1-micron particles! Polypropylene needlefelt on the other hand...

    I've seen one person on MFK using a large DE filter (Haywards is the brand IIRC) with good results, but you're right that they aren't particularly popular. I don't think filtering to 1 micron is at all necessary with the average aquarium, and far from practical with a tank the size of mine, it would be handy for dealing with things like whitespot on clown loaches though.

    I know the drum filter isn't the finest form of filtration on the market, but you have to admit that 40micron and completely self cleaning is pretty damn cool, at least for us big tank guys! I've certainly never seen anything else like it.

    $2500 actually isnt so much if yo uthink about it. An ultima filter is 2k nzd for a good sized one, 800 to 1k for a smaller one.

    all they do is what your sump does but more efficient.

    a self cleaning barrel is very good to have. no consumables, no cleaning, and stuff in the sock that further decomposes also compromises your water quality in time if left long enough.

    each to their own though, i owuld buy one if i had the cash:D never again buy socks, never again clean the socks. just feed, feed feed! and press a button in my case 3 to 5 times a week to change water!!!

    ideal!

    Alan gets the idea from dealing with rural water supplies for over 30 years where the treatment regime for a potable water supply was:

    1 presettling in a large tank to remove course sediment.

    2 filtering with 250-200 micron to remove the next lot.

    3 filtering with 50 micron to remove the next lot.

    4 polishing with 1 micron to remove disease organisms such as bacteria, giardia etc.

    1 micron filters will remove parasites and most bacteria but 40 micron will just make the water look good.

    You have a good day now.

    My two and a half cents.

    i use a 100 micron and been doin so for a long time, i have had 8 rotating 100 miron socks, 4 at a time in my set up, the media is no where near dirty enough to clean yet, and my water is quite clear.

    filter wool is much coarser than 100micron but that polishes up the water nicely.

    100 micron is plenty, i ried 50, but thta clogs very fast.

    and the clarity reward ratio to cleaning ws not enough.

    as for 1 micron, i believe that will clog rapidly and will require pressure to push water through? i mean, if it traps even parasites, heck - you cant even see that and your filter will clog pretty quickly.

    i agree with david though, to say that 50 or 40 micron is too coarse, frankly i find that ridiculous, canister filters will never provide more than 50 micron if they are lucky - but that is very succesful in keeping aquariums.

  16. Flow rates for filter media

    in Technical

    Posted

    Flow rate is an interesting thing, but as a general rule of thumb, you can work it out however you want in terms of sump flow capability and stuff.

    the more media you have, the less flow you can have, the less media you have, bio media, the more flow you must have.

    but th emore flow you have, the better mechanical filtration you will get.

    so you can work out your own balance that way.
