I went throught a ton of information from websites and searchs from other previous post, however I am still confused on what is the best way to promote coraline growth. I am buying LR from gulf view this week but want to get on the right track so my LR doens't die out. The tank is a 55 gal tank and is only going to be a fish only tank. I have a huma huma trigger and a miniatus grouper in there now and am done adding fish. I have another tank with LR but I have never been impelled to promote coraline growth. I have learned you need a calcium level between 400-450 and an alk. level of 3.5 and 5.5 meg/L or 10-14 dkh ( in fish only tank).
My first question is, will this hurt the fish in there currently?
Also, What are the best products to use in order to buffer and raise both calcium and alk. levels? (don't want to do a reactor)
I have read the recipe on the <a href="http://www.garf.org" target="_blank">www.garf.org</a> page and am considering doing that setup but i don't know if that is the best for the dollar.
And many people run kalk or b-ionic.
So basically what is the best for a 55 gal to promote coraline?
(product names and company made buy will help alot)
Thanks for your time and help!!!
tank has been up for over a year
