Ai prime HD questions

[Rickybobby]

Hey everyone. I’m thinking of buying an ai prime 16hd for my coral /frag qt tank. The tank I have is a tiny 2.5g possibly a 5g if I decide to use it. So the question is what light mount to buy. 12” or 18” height?? Thanks

My lfs mounting options are 12” or 18”

Depends on depth of tank, height of light, intensity light is run at and what corals you plan on fraging. That light will cover a foot print of a 10 gallon at 12"

I would do the 12" just to control light spilling a little bit

I may be wrong, but I believe the 18” can be adjusted lower but 12” only goes to 12” or lower. Personally I would get the tall mount with ability to lower it to your desired position. I use 4 on my 90 gal bow front. Have “18 mounts set to about 13” above water.
Good luck- happy reefing

update- I use the ridged one, not the flex mounts.

Or should I buy the adjustable arm so I can use it for anything in the future?

I would get adjustable personally.
