Proper lighting with 2 Radion xr30 Gen 3pros

[Scottyxcameron]

Hello everyone,

I’m having a rough time trying to keep most of my corals happy, particularly my acans. They never fully extend when the lights are on, however they are always throwing the feeders out when it’s night time.

With my best guess, I’m thinking that it has something to do with the lighting. I’ve been messing around with the settings and I’m hoping that the latest change is the magic touch! I just changed the lighting to the Coral Lab template with the SPS PHX14 setting. I have the overall brightness set at 25%. Start time is 11AM and end time at 9PM.

I have a standard 75 gallon tank( 48x 18x 21)
Mixed reef
Mp10QD
Mp40QD
Mag500
Eshopps S120 skimmer
Dual reactor (GFO+Carbon)
Bioblocks in sump

I feed reef energy twice a week along with NO POX daily(I usually wait 5-6 hours when dosing both)
I also target feed reef roids 3 times a week.

I plan on dosing cal and alk soon, just trying to get the correct amount per day.

Any advice, tips and comments would be GREATLY appreciated.

Thanks!!!

Bump, anyone?

Do you know all your current water parameters and if so can you post them up. Also acans don't like a lot of light or heavy flow and they don't do well in low nutrient systems.

Looking at your pics though it doesn't look like your acans are doing too badly and if they are putting out feeder tentacles at night then they are not too stressed. How old is your tank? going by the amount of coralline algae on the back glass and rocks I would guess six to twelve months maybe and if so then you may need to give the tank more time to mature and not put too many corals in it for a while. Also with the radions pick a colour and intensity setting and stick with it for 6 months minimum (resist the urge to mess with it no matter how much fun playing with the radions settings is ) because the corals need to adapt to the settings and they can take quite a while to do so.

Hope I helped

Alright, sounds good. I just get worried seeing them sunk into their skeletons.... parameters are as follows

(Did a water change last night)
Mag1300
Cal 490
Alk 9.0
Phos 0.00
Nitrate 1.5
Nitrite 0
Amm 0
Ph 8.2

Going to follow this...similar set up...similar parameters..same 2 lights in a 90 gallon. I have my acans about half way up on the side beneath my gyre...so they get the current being pulled into the gyre. They are doing fine. My issue is SPS growth. I run the Radion AB+ program.
