im having problems with my cal and alk i have had my tank set up for about 5 months and i still cant get the coraline algea to take off. i do 10% water changes every week and still no luck well today i went to the lfs to have my water tested and they said everything looks good but my alk and cal was a little low..they said cal was at 350 and alk was at 9.6 and told me to suplement my water with kent marine super buffer and kent marine turbo calcium. im not a big fan of adding stuff to my tank but against my better judgement i went ahead and picked those products up.. they told me to add 1/8 to a 1/4 tsp of turbo calcium at night and 1/2 tsp of superbuffer in the morning and to do this till my next water change this weekend and to test my cal and alk see where they are at and adjust if need be. does this sound right? i dont want to add anything that i dont really have to but i also want things balanced in my tank. and one more quick question while i was down at the lfs i picked up a flametail blenny they told me they are reef safe what do you guys think of them? thanks alot everyone:bouncer:
