I am concerned about the growth of two SPS frags I bought. I have had a Green Acropora Prostrata and a Pink Birdsnest (Seriatopora Tellata) for about eight months and have seen very little growth if any. For example, a tip from a branch from the Pink Birdsnest has grown only 1mm in this time frame. The Acropora Prostrata show no signs of growth. Both corals all show good signs of health ( extending polyps ect ). All my other mushrooms, polyps and LPS grow like crazy.

I'm not sure what could be wrong, but I have a couple ideas. My Alk is at 3.5meq/L, which seems low, and Calcium is at 420ppm which is good. I'm using Seachem Reef Builder, and Advantage Calcium. I've tried increasing dosage of the ALK supplement, but I'm above the max recommended amount and the ALK is not increasing. I have heard Seachem ALK & CAL suppelments are no good, so I'm looking at getting a hold of the E.S.V. B-Ionic 2-part setup. Other potential problems could be low nutrient and Iodide levels caused from over skimming, and maybe Strontium and Bromide levels which I have not tested. I also use Seachem's Reef Trace and Reef Plus, but I'm not sure if it's helping.

Does it sound like any of the above could be solutions?
What should I do or try?? Please help.. Thanks
