    It is when the bacteria and filtration system has reached such a high level that the nutrients drop to very low levels and some corals start dying, at least that is what I think it is.

    no, i dont think so. I think its a build up of detritus and such over the years.

    This is my opinion,

    You ever noticed how much flow your new pump pushes out when you just bought it and give it a few months and it feels alot less, basically Old tank syndrome is when our tank (everything included) doesnt run at its best capabilities or the way it should, the best way to beat this, is to peform regular maintenance on your system.

    When i say regular maintence i dont just mean you need to clean your pumps, how many of you clean the return pipe outlet for build of muck and other crap?....so thats what causes old tank syndrome,

    I'm not exactly sure what it is or what causes it but I have read that it is a good idea to renew your live rock after 5 or 6 years, in other words, remove some of your old rock and replace it with newly bought live rock.

    A number of factors, but the main one is competition.

    There are 2 forms.

    1. Competion for spcae. Corals like SPS that outgrew their space and overshadows everything else. Enormous pin cushions or Monti Pora's that shade everything under them. Corals that grew so big that they are now preventing proper water flow, resulting in more detritus settlement in tank building up. And the overgrown prevent the reefer from moving rockwork, or reaching behind the rocks to blow stuff out.

    2. Then competion in diversity. Like in your DSB, where a few live forms eventually outcompeted the others into oblivion. And you end up with only a few dominant types. Some can happen in your live rock. Only a few types of bacteria survived the 5 years of competition. That is whty you need to re-seed your DSB about 3 times a year. And you need to re-seed your live rock, with new pieces.

    I saw a tank that was once one of the European top tanks. But because of competition for space, it fallen into the old tank syndrome. Beautifull tank. Can ask Crispin for more detail. Reefer was forced to dratically cut back his beautiful big Arcoporas amongst other things, just to get better flow.

    ive spoken to him a number of times about why that tank took a dive (its not a tank crash as such just a detiration of the tank and its inhabitants over a fairly short period) and his tank was indeed magnificent from what ive seen of the pics before it crashed. Indeed it was voted into one of the top 100 tanks in Europe at its height.

    I think you are basically right (you obviously listened to him carefully! :)) and he thinks his primary three problems were shading by large corals, lack of diversity in bacterial strains and as hennie says lazy reefing.

    getting a tank to a stage that you need to prune back corals isnt that difficult and fragging corals thus allowing them additional space to grow out is indeed a good thing, but after a number of years the biological filtration seems to 'tire' and that leads to a drop in water quality and the consequental loss of corals.

    interestingly that reefer now plumbs a large frag set up into his system where he imports fairly large amounts of lr and corals, which is seperated inicially and then joined into the main tank after a quarenteen period. I think (my thoughts only) that increases the biodiversity of his biological filtration and helps with replenishing different micro orginisms vital to a tanks filtration.

    Yup, Riaan and Crispin basically nailed it :thumbup:

    That's not the worst of it - just imagine the frustration that every time you walk into a LFS you walk out again empty-handed, just because there is no more room in the tank for anything... not even a small frag of something.

    lol too true hennie, but remember the feeling of enjoyment to be able to split a large euphillia into 23 pieces and give them away to other reefers free of charge out the genorosity of spirit. feeding ones soul with the enjoyment of looking after a coral for years and then being able to give parts away to other reefers for them to enjoy :)

    PS of all the things that can lead to old tank syndrome, its lazy reefing that is normally the root cause, i think you nailed that perfectly

    You right new corals are our fix & then the corals we do have become part of the family & no one wants to cut them back! just get a bigger & bigger tank :)
