Frogspawn dying?

[sharuq1]

Size of tank?---14g biocube, been running one month and almost 2 weeks with LR and 2 hermits, tank was bought then also (so bulbs are new), runs about 84F, no bioballs or other filter media (only run a sponge on water change day/s for detritus, rinse it and take it out after tank has cleared), running small bag of high density carbon changed weekly, seio pump for flow directed to the top of the tank, not at the coral
Wattage of light?---Whatever came with it (10k and an actinic)
Water parameters?----Sg 1.022, pH looks to be 8.3 or 8.4, nitrite shows lowest color on the chart-slightly lighter than the lightest color on the chart (test colors only show 5 lightest color-110 darkest color, whatever that means), nitrate looks to be 0, so light there is no corresponding color, ammonia appears to be 0
----I do not own any other tests besides these.
**I am new to reading these tests and to me colors seem innacurate say in comparison to the nice exactness of a refractometer, so I could be wrong (wishing there was a digital version instead of all this color matching nonsense)
How long have you had it? Had the frogspawn only about a week
What ALL do you have for livestock and coral in this tank? *Especially with in close proximity* ---nothing is less than two inches away, 2" away 1 zoo and 1 xenia. I have 2 oscellaris, 4 zoo frags, 1 xenia frag, 1 frogspawn, 3 astrea, 3 blue-leg hermit crabs, 1 red leg hermit crab, nothing at all is touching the head of the frogspawn (no rock, corals, anything)--tank was started with only the LR and 2 hermit crabs initially, everything else added last weekend

**ps I realise that the tank does run warm, it is due to the lights/pump, not really something I can help
