Ultra Life will not harm any inhabitants, but 300ml in your tank was more than the recommended amount. Based on your water readings, you would only need to follow the regular dosage instructions.

Ultra Life dosage recommendation:
The normal dose of 10 ml for 40 L of water can be increased up to threefoldI recommend you run a 100 micron filter sock to clarify the water.

Judging from the photo, it looks like there is a build-up of UltraLife on parts of the live rock. Siphon out the excess.

Looks like a bacteria bloom to me. Some things to note if it is......the bacteria will consume a lot of oxygen so oxygenate the water by increasing flow and surface agitation. A lot of water changes will not really help since the bacteria will reproduce very quickly. Over a couple of weeks it should dissipate if you correct the cause (over dosing the Ultra Life) but you may nee a UV sterilizer to totally eliminate the bacteria. I had cloudy water/a bacteria bloom for a couple of weeks and it started to go away but a UV sterilizer knocked it out after 1 day of use.
