I just bought an iron supplement from Kent (as well as
iodine) and i will let you know if i see any difference in my bryopsis growth ;P . Actually i do plan on setting up a controlled experiment using iron dosing, salifert's iron test kit, some algae,
GSP,
Acro sp., and maybe a damsel or two. From what i have found, or not found, regarding iron and our tanks, there are some important questions that i am looking to answer:
1) does dosing iron boost
macroalgae growth?
1.1) does macro darken in color with increased iron?
1.2) does macro's oxygen production increase with increased iron?
1.3) how much iron is too much for macro?
2) does dosing iron boost nuisance algae growth?
3) " " "
phytoplankton growth?
4) does iron help coral growth (of various species)?
5) At what level does iron become harmful to corals?
6) " " " " " " to fish?
I am going to start running this study soon and i will keep you all posted on the results. Hey, this may be another good reason for a video cast!
