Maxspect Razor R420R 160 watt 16000k

I have been running one of these over a 30 gallon rectangle for a couple of months and can't seem to find the happy medium to keep all of the corals happy. I have it mounted on the light to tank bars that it came with so it is approximately 8" above the water. Does anyone have a similar set up and know what a good daytime setting is for proper par saturation? I have sps in the top half of the tank and zoas, softy, euphyllia in the lower 1/4 to the sand bed. a PAR meter would of course be the answer but I can't bring myself to spend that much money on a device I would very rarely use.

i have been having great success with my maxspect lights. i ramp up to 100% at around 10 am and run them to 6 at 100% until they start going blue for the night. crazy good growth.

[Dean]

Have you had any negative impact on zoanthids or palys?

[Scuba Sam]

nope nothing but crazy good growth on mine.

[Dean]

My lights are about 2' from my zoas and palys. I had the lights set at 100% for a week I have noticed a stop in growth and less extension. Do you have Zoas in your tank? How rom from the light if so?

There is a MAAST PAR meter floating around that someone donated. You might inquire to see who has it currently .

[Dean]

I asked Ben about it last night. Seems that it was never returned after the last person borrowed it. I wonder if any LFS rent them out.

I have mine on the stands that came with the lights. I peak blues at 80% and whites never above 50%(algae growth). Duncan is sprouting 11 heads toadstool is open all the way getting growth on star polyps and a group of palys. Green button sproutted two new heads everything else has not been in long enough to see any growth.

How far from your lights to the bottom of your tank new2dis?
