supplementation for softies only tank

I have similiar corals like yours. Kenya, colt, leather, zoas, mushrooms, xenia, green polyps and some brown version of green polpys. I read somewhere reef plus good for all softies and gave it a shot. it really does make lot of difference, got lot of growth in 2 months. I use 5 ml every week on my 80 gallon. I think it's rich in Vit C which helps leather to heal and grow quickly and also it has little bit of iodine, softies need iodine.

Like everyone suggested, dont go with kenya tree they take over very quickly. I need to get rid of mine soon.
