| Hi Mike
Yes JR does say that he waits for the science to catch up but if you really read closer everything he posted sums up at the very end, he finds it very hard to believe that the bakki showers are immune to organic build up. Like I said if you looked at the same bakki system with the same amount of media 5 years down the track the same fish would have grown very significantly there by increasing the load significantly as well. I don't think I have misread his posts if I did i wouldn have asked the questions I did in reference to the biology.
i respect JR very much and thus posted my questions.
Mike I don't know where you have got the golden rule of flowing 10% (as crucial) a day I can personally tell you most bakki showers flow in less than 5% a day. My friend roger flows in 10% a week in his insane stocking level and yet grows koi faster than probably you, JR and myself (true other factors were involved like high water temperature) for any given period of time. I flow in around 1.5% a day. You may even be flowing in more water than myself. The high flow in rate is due to the the heavy stocking, I have seen pictures of a 10 or 20 ton pond in momotaro with around 35 koi that are 45 to 50cm long. If you ask Mike Snaden he will tell you that you flow in water to maintain the water quality and we measure that by the tds level. If you have extreme stocking rate like momotaro and feeding as much as they do than yes you would have to flow in that much to maintain water quality. If you had 5 koi that were 15cm in a 50L tank then you may have to flow in 5% of water, but if you had the same fish in a 50,000L pond why would you want to flow in 5000L a day. How much water did SMG flow in to her tanks? did they run at a turnover rate of 1.5 times to 3 times? Now putting 50 fish (big and small) in a pond that is 13500L is pretty high stocking rate, and previously she only had 25 in each of the lava rock pond and the bakki pond, I would still consider that pretty high stocking rate. I get this feeling that people only catch on to what sounded negative about bakki showers from a experiment without really going through how the experiment was conducted, and whether it was conducted properly.
