I have one in the middleHow many gen 4 are you running?
Can you explain the ABS + program your running and where Can I find it please? I have all softies in my tank. Goniporia, Kenya trees, torches, EleganceI am running 2 gen 4 radion pros on a 48 inch long by 18 wide by 24 deep 90 gallon SPS dominate tank
I am running the sps AB+ program. I have the intensity at 80% (on the advance slider section) and my PAR levels are 300-450 at 6 inches and about 250 on average at 18 inches. The screens on the software are confusing. On the right side where you have the graph, there is a percentage. This is a percentage of the total power of the light. If you are running with ANY channel at less than 100%, this will NEVER be 100%. On the advance sliders you have slider to adjust the overall power of your program/settings in terms of percentage. This is where you reduce the light intensity. Adjusting on the right side of the screen has funky effects.
PAR levels can vary dramatically at the lower levels depending on your rock and coral placement. Shading and reflections can drastically change PAR levels. So these settings worked for me. Your tank could be different. If you have a different shaped tank or size or number or types of lights, your settings will be completely different. There is no one size fits all. On the Gen 4 Pros at 100% intensity the PAR was higher, not too high, but my corals were bleaching a bit and I lowered the intensity to 80% I may or may not increase in the future, but I am leaving the settings here for a couple of months unless the corals tell me differently. I can not stress enough the differences in the tank and how it can effect the PAR. My tank has a black background with a large center overflow and has a large euro brace. Almost everything can affect how the light makes it into your tank.
PAR levels can vary dramatically in a matter of inches due to these reflections and shadows.
