Although natural sea water is recorded at a KH of 8 DKH or alkalinity of 2.9 meq/L, there have been several studies stating that a higher alkalinity is beneficial in closed systems. Even Seachem states that “alkalinity should not exceed 6 meq/Lâ€Â. I have talked to several people that keep there ALK above 4 meq/L or 11.2 DKH and higher. Most state that “they†experience greater success and faster growth and reproduction rates, some even claim more intense colors on SPS corals. I also read somewhere that a higher ALK slows the growth of nuisance algae, I do not claim or believe this, just something I read.
I to believe that one of the keys of success is stability. There are so many methods to choose from, do what works for you. Every method has its pro’s and con’s……I believe more than anything it is all in the maintenance. If you let it go, it’s going to crash!!
And buy the way Russ, with as spectacular as your 90 is….. I can’t wait to see you new tank set up and running in all of its glory.
