Derek's 225g - Magnifica / SPS Reef

[derek_SR]

My guess is that high spread lights like Radion panels nail the front and cause crazy algae growth while the 90 degree reflectors on the ReeFis prevent growth. When my lights were angled slightly forward due to me waiting for my tnutz, the growth was insane (had to clean the glass twice a day). Now that I have them more vertical and slightly back, I can go almost a week without cleaning.

Before you take down the ReeFis, you could run Telegraham's file. The color differences are due to the overall # of diodes (ReeFis have way more violet and UVA than Radions so you kind of have to multiply the wattage of the LEDs by the % output to get an estimate or reduce their output to match colors). Then drive the royal blues harder. This is something not super clear to hobbyists that 10% "white" is not the same thing as 10% "blue" for any light really.

Absolutely is the case that more spread really accelerates glass algae - I noticed this right away when adding the helix bars, for example, and it's the most unfortunate tradeoff when seeking more spread. But it's a necessary evil to some extent.

This file is telegrahams imitation of the AB+ spectrum for Reefi?

Yeah it's an "eye match" to his GHL Mitras which have been calibrated to match the AB+ spectrum. Just based on what looks close to it since the lights sit next to each other on his tank.

@derek_SR
You’re tank is amazing!

Everything is going really well with the tank right now - so of course I'm going to make a major change to one of the most critical inputs.

If it ain't broke...time to mess with it!

If your Reefis are still up, can you load his settings and compare to your Radion in the sump?

Are these ase8 lights going to give you enough par for your sps?

I tested a single one over new 40gallon just filled with tap water for test purpose. I couldn't get par to go over 250, with the meter more than 3 inches under the water.

Granted i think i had it turned to max, output for the light. I couldn't get over 100 par on bottom of the tank either.

Didn't know what the heck to do with all the various different light colors, so I j Didn't mess with anything beyond hitting sps, and moving intensity to max.

…what’s 6 times 250?

Plus four 6ft helix bars. Should be plenty of PAR

So the spread of them stacks where the point of coverage will overlap between 2 of the lights? I also assume with 6 the goal is to provide enough overlap that there isn’t any serious drop of in par in any one section of the tank.

The bars you mention adds increase as well. Just following along in a general sense and learning from how your working your lighting.

Kinda why I'm playing with 2 of the newer kessils 360x on the 40gallon I have, intending to keep that one sps mainly, big one will be mix reef so won't need any crazy addtional lights for a while. Figure I pick up a extra 360x here and there as good deals emerge with zero need to rush to get things i don't already have.

Yeah running so many lights is really about the spread, and there’s so much overlap you also get insane PAR. I only run the Reefis at about 30% and still get 700 PAR in the peak spots.
