Starter corals? Feeding?

if it where my tank, Yes I would increase water movement
your tank is 75 gallons ? without re checking

but even with a tank full of just soft corals you want 30 - 50 times the tanks volume ( some will say 30 is to little and others will say , every tank is different, they are all correct in what that say)

so you need water movement total of up to 3700 gallons per hour in a 75
75 x 50 or 2250 75 x 30 - somewhere between is good for most people

in addition extra water movement helps with surface aggitation and thus gas exchange and PH issues

the saying is "You cant have to much movement, but you can have to much flow in 1 direction"
so 2 or more smaller power heads is better than 1 large one IMO and more imporantly in the opinion of more knowledgable reef keepers than me

Koralia power heads are very popular these days , check them out

I think you tank and your corals will benefit from Korallia 2s or even 3s located in each back corner and directed towards the middle

anyone have other opinions? - please contribute them

Ok, I purchased a koralia 3, we should place it on the opposite end of the 2 returns facing the toward them correct?

 

For parazoanthus, if they are not in good flow where they can nab particulate organic matter, supplemental target feedings of meaty coral foods is recommended. There's a reason why yellow polyps have such long tentacles when compared to other species of zoanthus.
