Hi , anyone running a zt6500 with sps ?

Ive not read a lot of users with that light here on r2r
IMO, your best bet would be to invest or borrow a par or lux meter to set the intensity. Color of the light has been debated since corals have been imported, Metal halide t12 compacts etc. 10k 14k 20k etc. And the same corals seem to grow well under each equally.
Lux meters are cheap and effective.

Thanks for the reply .Will see if I can find one around here . If not, what would one suggest , all blue % , all uv % and white % ? Blue running 28/32 , uv 22/32 , white 24/32
I will update if I can get my hands on one here

Looking at the par map here, Id look at starting low, and slowly increasing. 30% as a start.
Im a bit different in my color belif. Set the color ratio by eye, and make the tank look like you want, then adjust intensity. Here's why, 14k kelvin 10k 20k etc have all been hotly debated by aquarist since we started the hobby. the exact same corals are grown successfully under each. The same can also be said for intensity but theres a bit more to intesnity IMO.
But all reputable sources seem to agree acclimation is key.
