Please do not think im stupid. Im curious, I have a 125 and im putting acros in it all im using is kent tech a and b I was using kalkwasser but my aquarium store owner told me not to. The sps are doing very well, I only have 5. I am taking it very slow only adding one or two at a time. Are the kent trace elements a and b enough for a light load of sps corals. I also add a few drops of lugols iodine a week. Is this a reasonable way to do this. I have had a reef aquarium for years with the exception of the last two years. This is the first time im doing a sps only tank. Any suggestions. thank you.
