Aloha from Hawaii:
Had three objectives when I bought and installed a stack of 4 Blue Bins from Steve Castel filled with 20 kilos of BH media from John Sprinkle TBT of Twigs...
1. Improved water quality... Our ORP reading had topped out at the 350-370 and wanted to get it over 400.
2. Add a cooling tower for the hot summer months...and
3. Install a maintenance free bio filter to lessen my wife's work load...
Well, this morning after 7 weeks in service the ORP passed 400 to 404...Just cleaned the probe 3 days ago so I know it's clean and not reading high...(Was in the 390s all last week)
The August Heat Wave was early this year with temperatures at 90-91 degrees all of last week...Water Temperature, during the week, was a constant 74-76 depending on time of day...
Now I have to wait a few years to see if the media will clean itself as Maeda san claims...
All in all, I think the investment has already paid for itself...
A few notes: Water is pumped directly from the inner chamber of a Savio Skimmer filter @ 1000 gph to the Bakki Type filter...
Pond is 900 gallons so am only getting 1 turn/hr...
Fish load is 7 Koi, 4, 24+" ~ 2, 15+" and 1, 10" Koi...
An Aquadyne 1.1 BF is used as a mechanical filter feeding a 7 cuft TT and backwashed every Mon. Wed. and Friday...
All tests results for bad stuff is at Zero...
Aloha! Mike
