bro, i saw one reefer tank before..
he dosed kent marine (1 drop per day on his..... i think... 3-4 feet reef tank).
OMG LA.. all his corals colours are vibrant!!!
am going to get one (dose 1 drop per week?) hahaha
must google more information on this.
as i am changing water every 3-4 days with D&D salt mix.. not sure whether it's good to dose other things too...
bro take a pic of your corals / FTS.. then compare 1 month later! (thats what i am going to do
