Hi
The browing will be due to the requirement of AMIN and Organic.
Also if you are getting a white film the Bak level is too high and needs reducing. You can halve it at this point
The Bio is added initially for the first 4-6weeks then stopped at this point 25% media is changed and then re dose the Bio. Once you have the colony established the Bio can be stopped and only added when you replace media
Your issues are down to too much Bacteria activity and not enough food source as the corals are now competing with the Bacteria for food.
So next step as above lower the Bak dosing, raise the MinS and add Amin and Organic
One other important point, without fish the corals are not getting important elements and you will not get good results, it is vey important to have fish in a system that uses ultra lith
WHY?
You are stripping out ALL the nutrients from the system and at present only replacing it with building block amino acid, so as said above the corals will starve.
The thing with ultra Lith is that it is a potent system using only natural enhancement and as such can easily throw the results by over dosing and stripping out all the tank requires. So it is impotant to get the chemistry right
You are on the right track and the positive results you are seeing will increase with correct dosing and the negative will deminish.
Basically to sumerise - the system is suffering from Bio overload which is taking essential food from the corals - its a balancing act, but once found your system will explode with colour and growth
