Hi Pat,
As promised have looked through your great blog.
Everything seems to be going great so far
The Bio dosing is off as per the manual but as you are seeing great results probably not worth changing this for now but see how it goes. here is what the doseage of Bio should be
Standard dosing:
Shake well before use.
When starting to use UltraBio or after an exchange of the UltraLith filter medium add
1 drop per 100 liter every day for 2 weeks. After this initial phase,
add 2 drops per 100 Liter every three days, until the next exchange of the Ultralith filter medium. Please add the UltraBio either directly into the tank or into the intake of the Zeolite Filter.
It is advisable to turn off the skimmer for 2 to 3 hours after the addition of UltraBio.
The dosing for Ultra Bak and Ultra Min-S seems fine.
It sounds like you are already using Ultra Amin? is this correct, if so to what doseage.
In reagrds to colouration, Ultra lith is a slow process but also what makes fauna ULNS so successful as you are changing the system slowly not hitting the gas peddle a racing to the finish line, slow and gentle changes are always best.
In 4-6 weeks you can start the Ultra power trace elements and it is then you will really see tha colour come out.
