Weekend additions?

Here are mine (clowns, shrimp, 4-bulb t5 unit):

 

Still can't grow any coraline, but im hoping my new light unit and reduction of alkaline (9 to 4 me/L) does the trick. My future purchases include an anemone, shaving brush algae and possibly a blenny/goby.

 

Why would reducing your Alkalinity help you grow Corailine?
Good luck with the new additions.

 

Alkalinity was 2-4 times higher (at 9 meq/L) than the recommended value (2.5-4 meq/L) and was likely "burning" anything that attempted to grow in my tank.

 

Wow. How were you able to get the Alk. that high? Have you noticed any precipitation? Whats the PH,Cal, and Mag at? What are you using to test Alk.?

 

I was using backing soda to adjust my pH, which was a terrible decision. I haven't seen any precipitation or any growth of anything that (algae included). My calcium is at 460 and my pH is at 8.15. My alkalinity is now around 4. I don't have a mag test, but I do regular water changes, so it should be ideal. I'm using Seachem tests.

 

I got a cup coral on friday does that count? I found out today my Alk was really low... REALLY low lol.

 

Any addition counts! How low was your alkalinity? Was your calcium low too?

 

My Calcium was at 400 my dkh was 5.3. I've never had issues with calcium dropping. Ive been seeing some recession from a few LPS but all my acros were fine so I thought it might be my Magnesium, but it was 1200
