I’m no expert by any means but I have a Waterbox 20 Cube with an AI Prime light. I grow acans like weeds in my tank. Every acan in my tank started out as a 2 polyp-3 polyp frag except one.
Here’s what I’ve found:
They like moderate light, when they pale out or change color too much it’s usually because the white & Uv light setting is too high. They do seem to love blue light, for those interested I’d be happy to share a screen shot of my lighting schedule. Just PM me.
They don’t mind flow, and seem to handle many different types of flow I have them all over my tank, but most are on the sand bed in my tank. I have two small AQAMAI wave pumps in my tank along with my return pump. The wave pumps are located in different areas and set on random types of flow and intensity to attempt to create counter concurrent flow and reduce dead spots.
They like to be fed, I usually feed them lrs reef frenzy in a syringe or turkey baster to each frag once per week along with 2 broadcast feedings per week rotating between oyster feast, reef roofs, & reef chili along with a & b nutrition from Red Sea 2 times per week when I do my broadcast feedings. When I do my broadcast feedings I turn the return pump and skimmer off for about 20 minutes or so.
They like some nutrients in the water, I keep my nitrates under 15...they usually run around 2-10 max depends on where I’m at in my water change schedule.
They seems to be sensitive to magnesium and I have noticed that if my mag levels drop to the lower end of normal range my acans aren’t as open or puffy. I strive to keep them around 1400 or so.
They have been some of the most bulletproof corals in my tank, and all grow literally like weeds and have tons of new heads all the time.
I keep my calcium around 450-480, my alk around 150ppm. My ph runs 8.0 , salinity @ 1.025. 0 ammonia, 0 nitrite.
I do run a protein skimmer (eshoppes Nano skimmer) & do water changes of about 5 gallons twice a month.
Hope this helps!
