ok here is the deal i cant keep shrimp alive for some reason, crabs fine snails fine, corals and fish fine, shrimp died.. nothing has changed in the past 3 years and i have always kept them, so here is the readings
90 reef, 180lbs of rock 2x400mh 20k
r/o water
salt 1.025
calcium 400-450
rites-0
rates-5-10
amm-0
ph8.5ish
phosphate .05
temp 82-83
other than the ph up from 8.3 nothing has changed, i put 2 new cleaner shrimp in today and they were died within 1 hour, so i'm at a lose i have asked joel about it and we cant figure anything out have no answer so here i come to you all....i might buy a copper test kit to see if somehow some copper got in not sure how or why but you never know...but i thought that the crabs and snails would be bothered by copper if its in...i run a wet/dry skimmer and uv sterilizer had always have again nothing has changed. it is very frustrating.thanks in advance
