Thank you! And yes, id be happy to share. I have a mix of lights on different systems but for the most part I use Radion Gen 4s with T5 supplemental (ATI Blue Plus and ATI True Actinic).
Gen 4s I run Blue, Dark Blue, Violet, and UV at 100%. Green, Red and Cool Whites at 60%. Warm White at 30%.
For SPS I like to keep my par around 350-400.
Phosphates I keep around .1 and don't really track my nitrates all that much. I just try to keep them at Redfield ratio.
I feed twice a day with frozen and rotate between Rods food and PE Mysis. Food portion is probably the size of 1-2 quarters. I also feed nori once a day. I'm a big fan of KZ Flatworm stop and use it daily (money has gotten tight so haven't been able to get more as of late). I use Aquavitro Fuel from time to time but sparingly.
I mainly use Reef Fusion 1 and 2 for my Alk and Calcium and Aquavitro Ions for for Magnesium. The Ions also adds boron and strontium hence why I use the Fuel Sparingly. Ive also implemented kalk on my growout recently to help alleviate how much 2 part im blasting through daily as well as for the ph benefits.
I do run recirculating co2 scrubbers on all my systems as ive found a high, stable ph is a huge driver of growth and keep it as close to 8.4 as possible.
I do find benefit in carbon dosing but learned its very easy to go overboard. I don't know if you've ever heard the Lou Ekus' MACNA presentation on carbon dosing but if you have not its most definitely worth the watch. That being said I find my coral grows faster with carbon dosing and with such a heavily stoked system, the nutrients can be sucked up real quick if not careful. I have seen my nutrients drop so quickly that even heavy feedings would not keep my phosphates up, so coral began to pale. So here and there I take a turkey baster or two full of skimate and squirt it back into the tank, just enough to kinda put some back into the system without totally bombing it out. Its kinda that fine line of give and take. Good benefit but you have to monitor it closely as not to swing too much one way or the other.
A little higher nutrients I've seen contribute to more rich and vivid coloring in the coral so definitely important not to starve them.
