| Mike S's quote: Yes, the intention was/is to put bottom water directly over the Showers, without blocking. As for the 10% changes... this is something that hasn't been quantified as such. But, I have advocated using a TDS meter to determine whether the water changes are enough or not. JR seems to have quoted me on Koiphen as saying that water changes aren't necessary, and that a TDS meter will tell you if any water needs changing at all. This has never been the case! I have always maintained that water in a Showered pond should be changed in the same percentage as a conventional pond.
As for the 1500 ton pond... these Showers are an add on to the pond, and as such, the water that feeds them, is drawn though the pond wall, straight into a pump chamber, and up over the Showers. For the life of me, I can't figure why they clean the 1500 ton pond?! Daisuke says that it is because the pond is so big, with the drains being so far apart. They literally scrub the walls and floor, even though, to my mind, they are always clean anyway. It doesn't matter how fantastic the water is, they still drain it! As for water changes on this pond... 3 to 5% per day is the norm for most of the year.
Hi Tewa
My understanding from the above posting is that:
1. There should be daily water changes for BH
2. 10% change and use tds meter to see if this is enough
Nobody has replied on whether BH used in submerged manner (as in Maeda's 1500ton pond) may or may not have anaerobic biological activity. Any idea?
To be frank I am a "hater" of Momotaro kois as what I have paid for so far had not given me the quality that I expected. Maybe I was not good enough at selecting Momotaro kois, or at the price range I usually pay for Momo kois (US$2-5k) one should not expect much. That doesn't mean I should hate his media altogether.
JR has got a point on the many snake oil products that had come and gone. We had been bitten by the many cobras too many times not to be wary. So far we have been told BH is very good. But how good really? I suppose the best way to know is to see or try it myself. It will be nice if JR can take up Mike's offer and give us some feedback. Mike is the offer open to all?
Thanks, dtbh
