Did you have any issues with kind of mini cycle when u added the live rock?2 years for my bare bottom dry rock tank to be work with SPS. I added 2 pieces of live rock at about the 12-14 month mark and it still took a long time.
BRS 7 stage for RODI. I change DI resin based on color change which typically matches with TDS going to 1. Surprisingly I haven't needed to change filters or carbon block or cation resin in 12 month. Anion resin however runs out very quickly.Dry rock
Nutrients too high
Add some aquacultured rock
What are you using for RO/DI and are you changing filters and resin out when it hits 1tds?
Thanks for the recommendations...so without knowing the need for flow of individual SPS, I placed my frags over different spots but no luck. The lowest rock surface has the green birds nest and another coral that was doing well and then suddenly about 2 weeks ago puff...it started dying. The highest rock surface towards the right of the tank had a very chunky frag (my biggest frag from H@rrys). It did very well for 4 months and started browning own last week and at the moment is almost completely brown.You got some very good advice on nutrient levels, see if you can source some birdsnest from someone who has similar nutrient levels. I have a few other observations:
* Your wavemakers are pointed up. In a 96" tank, you are definitely not getting good flow in the middle of the tank. The one on the left should be pretty much level and about 4-6" below the surface, Make sure you're getting around 10 cm / second of flow in the spot where you are putting your SPS. And the flow shouldn't be hitting the coral directly, it should be going a couple inches over the top of it.
* How much coraline algae are you getting? I can't tell from the pics. Put corals where there's good coraline growth.
* Make sure new frags are placed in the same PAR as the tank you got them from. I recently fragged a couple montis and moved them from 200 to 500 PAR (same exact water chemisty). Bleached and dead 2 days later. Any change is pretty rough on corals.
I have 2 sand sifting gobies always sifting through the sand, do we think they will help clean the sand to some extend and will adding say a sand sifting sea star help with cleaning the sand?I would like to add to this:
if your tank has been up for 2+ years I would recommend using this practice. if its younger I would try and keep the sand bed clean right now. I clean my entire sand bed every week. you can stir it up in any part of the tank and there is no cloud that comes out of it. I have had a super clean sand bed and I have never had issues with SPS in the tank.
At least if I am confident that its all from immaturity of the tank and not from me doing anything wrong, I have no problem waiting it out. I already know the adage " nothing good comes too fast in this hobby". I can at least enjoy my fish and add some more fish, LPS and equipment while I wait. But I want to be sure.With NSW being at 7, yes I consider 9 high. The problem with running a tank on the edge is always that stability becomes even more important.
In the case of the OP this isn't an issue just wanted to add this for future reference for people reading this thread.
In case of the OP I think this tank is still not mature enough for SPS, given the nutrient swings the bacterial biome is still developing.
For a 96” x 30” foot print and your aqua scape I think adding the star fish might suffice, but if you don’t want to perform the sand bed cleaning maintenance, you may want to add more sand bed cleaners.... like more gobies or/ and I would throw in 10-15 nassarius snails to help out. And this would be due to the depth of the sand at 3”. My 75g has a 1” sand bed, I like it, but I have to trip the posts of frag plugs if I want to place them in the sand haha cause they’ll fall overI have 2 sand sifting gobies always sifting through the sand, do we think they will help clean the sand to some extend and will adding say a sand sifting sea star help with cleaning the sand?
I actually do sand bed cleaning but not as frequent and I do a quart of the sand at a time. I always worry the gobies might not have enough to feed if i over clean it.For a 96” x 30” foot print and your aqua scape I think adding the star fish might suffice, but if you don’t want to perform the sand bed cleaning maintenance, you may want to add more sand bed cleaners.... like more gobies or/ and I would throw in 10-15 nassarius snails to help out.

Also when I clean my sand, cause I should have given you my method, I clamp a filter sock in my sump and then go to town cleaning the sand and the water is put back into the sump and the nasties go in the sock. Using this method, you can clean the sand for an hour + and
I would suggest changing them all out at once, especially if you're having problems. How do you know you haven't needed to change out your carbon? prefilters are cheap and affect your system pressure.BRS 7 stage for RODI.

Will adding aquacultured or live rock at this time potentially start a mini cycle from die off, etc?
because my system pressure has remained at 78PSI since installing. I understand the pressure should drop if its time to change according to BRS.I would suggest changing them all out at once, especially if you're having problems.
