Sanity check please

I'll give my schpeal again to save questions about my setup. But I am starting to see not so good things with a few of my corals so I am second guessing myself again.

My 200gl tank has been up for 4.5 months now. HQI (2 x 250w 10k/14k)and Compaq lighting (4 x 95w act), large fug (Approx 50gal packed full of grape caulerpa with lights on 24x7 for stable PH levels. Never even really had a cycle because of it (silent cycle) , 200+lbs premium live rock, great waterflow (2 x 1200gph Blueline), Euro skimmer and Prime chiller. Water params have been perfect since 1 month up. PH 8.4, 0 Amm., Nitrates. Phos and Alk right on. Calc could be higher (360 /9Dkh) but my calc react / wasser is not up yet (using a buffer though).

Have Naso Tang, Midas Blennie, Royal Gramma and 5 green chromis along with cleaner and blood shrimp, 2 sea slugs, a few snails, a few Emerald crabs and of course about 50 or so small blue legged hermits, 2 types of green Blastos, Frogspawn, several Ricordia, few chunks of Zoos -all of them are very happy and thriving......

…..However, just within the last week I have noticed that two (out of 5) of my neon green blasto polyps as well as all of my Trumpet polyps seem to be withering a bit. Whats up now? These guys have been in the tank for about 2 months now and we doing fine. Water Params still right on.

I feed once a day with homemade fish/coral food (pureed mussels, oysters (and oyster eggs), fish roe, squid, fish fillets, shrimp, sea weed along with a chunk of Cyclops Ease. I tried some phytoplankton for a few weeks but didn't see anything noticable and asked around and everyone thought the food I make should take care of just about any fish and corals?

I turn power heads and one pump completely off during feeding and throttle the other pump back with a valve so just a small current moves the food around just a little and gets the fine stuff into the corals. I do not put any additives or trace elements in the system (yet and was hoping to not have to).

Anyways, so I don't lose your interest here, can someone give me any ideas? Am I overskimming possibly?

If possible, if someone could maybe give me a sample of what their weekly or monthly maintenance, feeding, additives etc schedule looks like that would be a great help. Again, I have been reading tons of stuff but this is my first tank and now that the “rubber is meeting the road” so to speak, I don’t know what I don’t know yet – Devil’s in the details with this stuff right!

Sorry so long winded but I wanted to address any questions that might gets asked….thanks in advance for any help!

Just don't make my mistake: what's your salinity? I went over a month not checking and testing the heck out of everything else... guess what it was?

I thought 2 x 1200 would be enough for my 215g. I'm up to something like just under 10kgph.

SG is 1.024 ....has been between .023 and .025 since start up.. I check this weekly. On the water flow - I have a valve on my pump that feeds my chiller so I can throttle the flow back - I have to or else I would have everything blowing around in my tank - too much...water flow is extremely good. Three outlets on one end of the tank off of one pump, and two outlets at other end coming off my chiller pump. Also have two Maxi-jet 1200 powerheads with rotating deflectors so I have a wide variety of flows and currents in the tank.
