| To calcium or not to calcium
Hello everyone,
I am new to this saltwater adventure of building and maintaining my 75 gal mixed reef tank. I have had many setbacks and frustrations, but am beginning to get into the swing of things.....I think?!? Anyway, my latest issue began with dying snails. The snails I first introduced into my tank appear to be doing fine, but ones added later almost immediately appeared to die. I tested my tank numerous times and eventually found my calciium to be a bit low (340ppm). I added some liquid calcium and snails I thought were gonners...resurrected and became much more active. I also lost a condi anenomie (to late for help for this one). I have been adding calcium regularily, with regular testing, and have experienced no more invert death (for which I am glad as I do suffer from survivor quilt when something dies due to my ignorance).
Today I read that one should not add just liquid calcium without a buffer (alkalinity). Is this true and what is it that I get?
Please help a poor girl out.
Thanks,
Sherrel |
