Hello....not being a smarty here, but the browned out condition is an overpopulation of zooanthalle, due to high PO4 and/ or low light conditions. The corals natural pigments, (colour)' are produced when the zooanthalle balance is reduced, where water parameters, lighting are sound.
The green effect is brought on by higher spectrum lighting to browned out SPS, i.e. browned off SPS glow green under blue light. SPS true green will be fluorescent under lower K light ratings, Dallas is a good examples of this.
It's great you've recovered your tank, and added a test coloured stick, this will be an indicator of water parameters and stability over time. Good luck and I admire your commitment.
If I could provide you with one piece of advice, it would be to purchase a nice second hand tank and equipment at least 1200 x 450 x 450 and give that a go. Brand new....even better. Good luck DarkSparten.....May the gods be with you!!!! :)
