OK, here i go again back by strong demand. Actually I was stalking the board until Aqua digital offered the review....
any ways, I have been battling many types of Algae's , from Bubble, Red turf, and Green turf, along with some low colors from the PO 4 Now i do 10 -15 gal per week on my system. I used to do only 5 gals ,but Mike AKA Aqua digital suggested that i boost it up when I was doing the Ultra lith to aid in getting that recommended % of weater changes done each week.
THIS IS WHAT I'M DEALING WITH IN MY TANK.

that one is the bubble algae all over the rocks
-----------------------------------------------------------------------
So I started this on 18th of Jan after getting back from out west.
PO-4 was tested heating the water to 80F the test was at .01ppm.
from reading the instructions that it states that 100ml per 75 gal's
This is what I received from Aqua Digital for the trial.

VERY IMPORTANT THAT YOU READING THIS

This is the test Kit that i use.

This what My tank was sitting at before I left to head to BC.
This is what my PO4 Level was at before I tested. Aqua Digital stated they like to see the PO4 level at a higher state when using this stuff since you get the greatest improvement out of the ultra phos. But I told him I would Like to still give it a go. At this level it will start slower down the Coral growth.

Now I have used the proper amount and only used 50% of the recommended dose for the 1 week to see any difference. not much of a difference. Just wanted to get the tank use to the Ultra Phos. I'm dosing Kalk 24/7 through my Barr Aquatic's KR3020 stirrer. ALong with Im running Carbon in the same reactor too. And Im still using the Ultra Bio that i was on. Mike Should I stop that or keep going with that stuff. DO you want me to continue with that trial with that Ultra Bio too.
