I would aim even higher than that. 140 ppm is roughly 8 dKH and that is where I like to be. 80 ppm is about 4.5 dKH which is way to low for SPS.

Here is a conversion chart. I think most will agree you should be somewhere between 7 - 10 dKH.

Hmm, just a thought... how did you acclimate your crabs when you added them to the tank? Did you drip acclimate over the course of a couple hours? If you didn't slowly acclimate them, that is likely the cause of their death rather than some off parameter.

I really want porcelain crabs in my tank but they don't seem to survive.

I tried one from big als first,
after the drip for 3 hours it died within about 2 hours of being in the tank

then on my second attempt i bought 3 thinking it was maybe an unlucky crab and dripped for longer. One died in the drip chamber, the other two died after about 2 days.

definitely something abotu my water conditions that is killing the crabs.

I'm gonna invest in a slew of new test kits to get a better idea of what's going on with my tank.

Salifert are a good quality test kit and a bit cheaper than Elos. I much prefer the Salifert alkalinity kit to the Elos one as well.

My alkalinity is

2 meq/L!

that looks low according to everything I"ve read. Any ideas on how to fix this?

By using this calculator: http://reef.diesyst.com/chemcalc/chemcalc.html

For a 30 gal tank dissolve 2 tsp of baking soda in water (I use RO/DI) to boost your alkalinity from 2 meq/lt to 3meq/lt

Dont add the solution all at once to your aquarium, add a little at a time perhaps over a day and keep an eye on your pH if you can.

+1 on the salifert kits i like using them too easy to use. i have never had any problems with them ever since using them....
I also know that a sudden drop in ALk will cause you SPS to die too... that may have been your problem too, any sudden change in Temp by chance, or PH
