Ca, Mg, pH, Alkalinity & your Zoas

SeaPug.

Me personally as much as I preach to ensure parameters are in check. I don't check as much or anymore. I use my xenia and zoanthids as indicators to my tank parameters. Plus with weekly to bi-weekly WC's, I don't bother anymore
 
Yeah, I do weekly water changes and periodically check my alkalinity (been doing it more lately though). It keeps things generally acceptable, but I did a nitrate test for the first time in almost a year last week and noticed it was a bit high, so I'm starting the vodka routine (very carefully) so see if I notice any improvements over the next month. Day 3 and everything still looks the same. Tomorrow I step up to the Phase 2: The Double Dose.
 
Agreed, this is great for us new folks. I keep a fair number of Acans so I've been boosting my Mag recently. Probably around 1,400 and I've noticed that my zoas and palys seem a little happier and more colorful. I'm sure this is in part due to Ca and Alk being more stable as well. I dose a 2-Part to keep my levels in line as my tank seems to suck Alk and Ca even with the high Mag levels and a mostly LPS/Zoa tank. I can definately tell when my Alk is low as the Zoas get PO'ed at me and the Acans shrink.

I don't seem to get anywhere near the growth that others report but my tank is new and honestly, since its small, I don't need things growing like weeds on me.
 
Hey there, I do 10-15% water changes daily using triopic marin salt. And i dose 2 part bionic by ESV. Keeps my dKH at 8.5 and Ca at 390. I have a 90 display predominately sps and I do exactly the same thing. hope this helps. Al
 
10-15% water changes daily...really...daily? That seems a little like overkill, but if it works for you...
 
How about ph swings? Are you using chaeto or kalk at night? I am setting up a zoa only system and curious about how well they handle ph swings.
 
Hi,
i'm a newbee in the hobby, and starting a zoa collectioni have zero expirience in keeping them so every bit of info is intresting to me.
So here's a litle bump from Belgium to keep this thread alive:thumbsup:

Happy newyear
 
Great read on this short little thread. Very informative. 90% of my Zoa's have melted in the past year or so. I finally got motivated to figure out why. I keep a log of all my aquarium chemistry in excel and while I don't measure often I was able to look at it and determine that the main reason that my zoas vanished was low alkalinity and PH. My calcium levels are always high. One thing I have never measured is Mg I need to bite the bullet and get a kit. Not sure why I didnt start adding supplements to raise Alk and PH. Anyhow currently have my Alk and PH under control just need to maintain it and see what happens.
 
please let us know of your progress..even if thread is old,,its still a good topic to carry on talking about,,especially your future results
