    Hi cklee,

    For traditional filtration, rule of thumb is that the filter size to be 30% of the of the pond size. But with Bead filtration, the size is a lot smaller. What do you mean by retention time? I believe you have meant water turnover rate. Normally, hobbyists goes for between 1 to 2 turnover rate. A few even go for more than that. Example, if it is a 10 ton pond, and uses a pump with rating of 10,000 liters per hour, then the turn over is 1............

    Hi abang Shukri, actually i plan to make a new pond for next year. but i thk that 30% of the the pond is too big for me.i willing to keep more space for my kois....is that anyway to reduce the filter size but wit good efficiency??
    Regarding the retention time, can i say is volume/pump rate,how long for those dirt n partical to settle down in bottom of the filter??so that the water can clarifying in filter??
    (pls correct me if i was wrong)

    Hi uncle cklee, maybe you can do a 20% chamber filter type and then a bakki shower.
    Just my thoughts..

    After having seen many disasters experienced by people who went for marginal calculations, my humble advice is to go for the maximum - and definitely not less than what Bro Shukri has recommended.
    Koi grow, and we also tend to keep on adding. This will be fine, but up to a point. When things go wrong, they often do so very suddenly and tragically.
    Some of these tragedies come about because the koi have simply outgrown their filtration system unnoticed by ourselves, and in some cases, emergencies like power failure, water cuts, etc.
    Our hobby is for our enjoyment - not to be a cause of tension and misery when we find out that we have under planned ? :)

    True, after all, the filter is the heart of the pond, without it, the kois will perish. Goes back to the saying "look after the water and the koi's will look after themselves"
