Ok I have a question for you all. I have a JBJ 24 g nano. I have had it going about 3 moths and all is doing well I thought. So i added some Zoo's last weekend. They hardly come out. I wentback to the LFS and they said my calcium might be low. I had not been testing that. So i bought a test kit for that and alk. My Ca seems a little low. Please let me know hwat you think and what to add.
Started with RO water and 20lbs of live rock
ph 8.3
trates trites and nh3 @0
Alk 4
Ca 210
I have made sure nothing is bugging them and I have stock 72watt pc lighting. New mh retro kit came today.
What do you all think. A little help would be great. I have
3 hermits
1 turbo (mex)
1clown goby
1 randalls shrimpgoby
They all are great.
I feed them Form frozen and add coral plankton for the zoos. is this ok too? Its what the lfs suggeted. Thanks again Mojo.

I haven't heard about low calcium being a problem for zoos, but maybe. You calcium is a little low, you can raise it slowly using a two part additive or CaOH. You Alk may also be low, depending on if it is in dKH or meq/L if it is meq/L it is good, just high compared to your calcium, if it is in dKH is it low and should slowly be raised like you calcium.
But, I don't believe low calcium is why your zoos aren't opening. I've had problems with various zoos that just decide to one day stop opening. I've found many zoos seem to like high flow. Try moving the zoos around and leave them in a new place for a day or so, see if that helps. You can also try dipping them, in my experience some zoos get covered in a very thin slime that if you brush off lightly they open up better. Just some ideas, hope they help.

you should bring up your cal, and if your alk is 4 meq/l i'd say it should need to come down some. I'd check your fresh salt water before you add it to your tank.
levels to shoot for, as were told to me.
alk 2.86 - 4.29 meq/l
calcium - 400-450 ppm
As far as....is this the problem....i don't know. but it may be.
