You have a few thing to look into. The SG
is too low, especially for sensitive sessile and mobile inverts. 1.025 would be alot better and should raised slowly over the next few weeks. With only one MH
bulb, you will need to restrict the SPS
to that general area. It is recommended for better coverage to have one MH
bulb for every 2 ft area of the tank. Adding another would increase the areas in which the SPS
can be placed.
The chemistry is pretty good although the alk
could be bumped up to about 11 DKH
. Was the ph
tested soon after a water change/buffer addition or late in the evening. 8.5 is a little high for an average reading.
The water flow is good although I hope it is distributed well. After HP, the return will be about 700 GPH
but the Turbel is about 1500 GPH
. Not sure how the rest of your corals are fairing but the SPS
will love the high water flow as long as they are not directly in it's path.
, 6 months is still a little early for SPS
but if you want to "get started" I would suggest one of the easier ones first and not the acro
's. Monitpora are probabley the more attractive and easier to keep from that list.
