Critique my lighting profile

[monfilsi]

Opening myself up to critique from the community!

Below are pics of my tank and the measured PAR. PAR is measured on a Seneye usb for whats its worth. I know its not very accurate, but better than nothing!

The measured values are obtained when running my lights at 40%. Don't think I'll be going above 40% with some of the par reading I'm getting.

Running 2 units of reefi uno v2pro.

Pretty impressive I must say! Can you give us tank dimensions, and how high above water lights are

 

[monfilsi]

I'm on the metric system so tank is 730x500x1000mm (Height x Width x Length). I have the lights mounted about 25cm up from the water surface as that seems to be the best spot to minimize shadows based on my scape.

A bit too strong in my opinion, especially for the lps

 

[monfilsi]

Bump for more critiques. Running too high?

How long has your tank been running with those settings? All your coral look healthy. I would t change anything if that’s the case.

I think it seems high for lps...but lps can be acclimated to quite high par levels. How long have you been running it this way? What lens are you using?

These are new lights that I just swapped in. Previously light was about 100 par lower on the other lights.

I’m not running at this level yet. Was going to acclimatize to it this level over the next 40days.

Ok! I agree with the rest of the people responding then. Those levels are pretty high for the corals you’re currently trying to keep. Your tank looks healthy and beautiful. I would try to match the settings of the new lights to your previous settings.

Using the new 90deg reflectors from reefs. Not seeing the rainbow effect that some others have complained about with reefi.

Here was measurement on previous lights.

I’m running close to this at the moment and going to gradually ramp the new setting.

I have one reefi pro2 over my tank and i run the 120 lens about 11" off the water. I am using 125w at my highest setting getting 220 par about 12" down, 190-200 near glass. Love the light.

The amount of par you have is very high, acclimating to that over 40 days may be ok but you may want to back it down a bit. Care to share your settings?

 

[monfilsi]

Seems like a good consensus that new settings may be too high. I was a little worried about hammers in the middle and was going to shade them a little.

Ill dial it back a bit.

Was seeing slow grow on my acros that is what led me to upgrading the lights.

Yeah thats a big jump near double in some places.

 

[twentyleagues]

How many watts are you using to get those numbers?

 

[Uncle99]

I measured the light PAR from my LFS which keeps only corals for 15 years now.

The average PAR was 155 with 80 on the edges. Only the higher light acros and clams are kept separately and they are 250 with 100 on the edges.

It’s so easy to overlight.

Maybe that provides some reference.

Imo the grow very slowly under high par values but can tolerate it.

I agree. It's not ideal most of the time. Typically torches and spawns in the low 200 range is usually low end of high for them, hammers can go high 100s, meats and things like it, plates, bubbles really don't do well over 150. Zoas are all over the place I have/had some sitting near 200 and they are reaching others in 100 seem to pretty much hate that level needing to be lower. Some acros in 300-400 seemed to do fine. I had others that grew like crazy in 200ish and would not grow in the 300+ range.

Op whatever you decide go slow.

Here is the profile I'm using on my 2 feefi Uno

Measurements in this thread were measured at the "Peak" level which runs for 3 hours.

Thanks everyone for the great advice!

I'll dial it back some and might move a few lps around to avoid hot spots.
