Low absorption

Hello
I have a 100 gallon reef tank. Although my corals look fine they don’t seem to grow much and my absorption of calcium and Alkalinity is low. Presently they reading are Cal 425, Mag 1330, and Alk 10.25. All measure via trident and Cal and Alk reading confirmed with Hanna. Lights is 3 - hydra 26. I would have to assume something is not right. Any ideas would be appreciated

What species of corals are we talking about? Some grow slowly. Others don't use much calcium. Still others will only grow well under optimum conditions. A few picts of your tank will also help. So will the lighting profile you are using with the Hydras.
