Rule of thumb on how fast I can crank up light intensity (LED)

[Reeferparty]

Title says it all, just wonder what the general rule of thumb is for increasing intensity. Don't want to shock my corals but want to get to a higher par as soon as possible; but safely. How much par/percentage weekly or daily?

I'm currently at about 150-160 at the highest peak of my rockscape. Looking to get to around 300 asap.

Thanks

Rule of thumb is use a PAR meter. Which you have.

However not everyone can, start low, really low and go slow, go damn slow.

25-50 Par every two weeks seems safe to me.

What lights do you have?

The reason I preach this is because up until the G4 and Kessil AP700 LEDs had extreme hot spot and that is where the problem is. I don't think starting and acro at 200-300 is a problem. The problem is when you have places of 700+ under the lights that kill without being acclimated.

Single fixture ap700 on at 47" x 20" deep. Updated the ASM/PMK last night and I'm seeing more plausible readings from it today.

I also have the Kessil AP700 and started at 30%, added 5% every week until 50% then added 2-3% each week. My two lights are 7-8" from water.

Should be able to go to 300 par right away. If you want to go higher I would go much slower after that.
