I was just going to ask that, My Xenia does look pretty sad and I really hope it will turn around, I was also going to ask, if it does die what will it look like? I checked the PH and my test kit only has a place for 8.2 and 8.4 and the color was in between the two so i am going to say it was at 8.3. I am pretty sure that I wont see instant results with the Xenia but how long do you think it is going to take for it to perk back up or is that just gods will. Also if the brain has bleached in an area does that mean that that area will be white from now till forever or will it grow back? In terms of the calculation I did do it as far as 1/6 teaspoon but i dont have anything that will mesure out 1/6 of a teaspoon. Also what test kits do you guys use because I use FasTest but all I have is the basic tests (trates, trites, ammonia, PH and I bought the copper one.) I want to know because I need to know about calcium and all that other stuff.
