starting a coral tank

[Canuckgod420]

How do you divide a 75g tank into 1/3 reef tank?
I dont think you bought clove polyps, if they pulsed in store it is most likey pulsing xenia, and they like fairly strong light and medium flow.

[eWarren]

Yes, you are right. I think I got xenia. So, do you think its the light issue? I do have good wwater flow.

Read and found myself Ca is held back by Mg. Likes a 3:1 ratio so try raising your Mg to NSW (~1280ppm) for a higher Ca.

To get the Xenia pulsing can be hit and miss but they do seem to like a higher pH to pulse (8.3).

[eWarren]

If finally I get my water to the "ideal reading" again, will my Xenia pulsing again?

[marie]

Nobody really knows for sure why xenia pulses. Some people with "ideal" water quality can't even get xenia to survive so thats a hard question to answer

Just for the record anything above 380 is fine for calcium, i've found 450 to be a bit too high (it's more likely to precipitate out and cause a bit of a snow storm)

Warren Great to see you on Canreef.

Getting your Mg up will likly help with your CA. But really I don't think 350 - 390 is all that bad for soft corals.
how is your Nitrate, Ammonia, Nitrite. Also since your tank used to be a fish only did you ever treat the tank for anything using copper?

I had xenia's in my last reef.

They never pulsed unless I turned the pumps off & then they pulsed liked mad.

I redirected the flow around my tank to make a slightly calmer area, moved the xenia's over & then they were happy and started to pulse & spread like wildfire.

Even I just have fish tank, I have live rock since day one, therefore, I never use copper in my tank. mmm... about nitrate, nitrite and ammonia, In the beginning of first 3 month, I check these number. But after then, fish are fine, I stopped measure them. What kind of salt mix do you use?
