Thanks Vinny. I used to use it a few years ago but have been using Ultra Power Phos for the past few years. I always felt I got better results with Ultra Phos so looking at changing back to it once I've run out of Power Phos. My Po4 is usually around 0.075 but I run 2 bags of Power Phos with 25g in each. I change one out for fresh each week alternating between my blue bag and white bag but I still seem to end up with slight diatoms on the sand. I've recently changed all my RO filters (membrane/pre filter/carbon) and get a TDS of 3 post membrane and 0 post DI.
My tank is 100 liters and my current dosing is:
2 drops Ultra Bio daily
0.2ml Ultra Bak AM
0.2ml Ultra Bak PM
0.2ml Ultra Organics every 2 days
0.2ml Ultra Min S every 4 days (always on separate days to Organic)
I run 20g of Ultra Carb L which I change every 2 weeks and perform 10 liter water change weekly with FM Sea Salt
My NO3 seems to be at 25 but I have been feeding frozen food on week ends.
I don't have a picture at hand but this is a short video I took recently. I have since added a few more frags (Duncan/caulastrea/purple stylophora). My Green guttatus has great polyp extension but seems to have lost it's green colour and is more brown but growing well. Potassium is 430 just now so waiting for that to drop.
The last tests done this weekend were:
Temp - 25.9
Ph - 8.2
NO3 - 25
Po4 - 0.075
Alk - 11 (I've reduced the amount being dosed via my doser - FM Balling salts/trace elements)
Calcium - 450
Magnesium - 1350
Salinity - 34
Potassium - 430
