I copied a PM I answered, I thought I wrote all this before, but here is again, just what my system is made up of:
Thanks! It's a self-drilled 75 glass tank, 3 overflows (one on opposite end incase nem walks and clogs on one end, water keeps moving). (2) T5 ATI special 54 watt lamps in rear, 2" off watter. Reefledlights.com LED DIY, made up with XRE, XPE, XPG, maybe 5 years old?. I think there's 68 LED diodes on each side, (2)18" heatsinks, one may be 22" long, don't remember. Each gig gets a home depot 5500K daylight LED Phillyps spot light (clamp on rim of front tank) I think 12 hours of light a day, 8 hours of full/blasting light. There is a TON of light on this tank. (2) MP40 set at reef crest on high, no change at night. Very turbulent, sand moves sometimes. Special grade reef sand, I've changed sections out at a time. depth changes between 1" in the middle, to 3-4" on ends/behind rocks. Algae gets sucked out with water changes, as much as I can. Just regular reef crystal salt. 5-20 gallons at a time, sometimes a couple times a week, sometimes life is busy and they don't get a change for a few weeks. There's about 8 different types of algae, bubble, hair, (all the pests), grape, some red type that grows in clumps, calerpa, I don't know the rest. 30 gallon long AGA tank for a sump, so basic. Water overflows to sump tank, skimmer, return pump. NO light in sump, no filter sock, just collecting detrious that gets sucked out every few months, and sponges on the walls. 2 part dosing seachem fusion or b-ionic, with timers and dosing pumps. Top off RO water ATO. I live on a well, only use RO, not DI. Front left corner of tank leaks, has for years. Real nice, huh? salinity varies from 1.026-1.028 if I don't pay attention sometimes it creeps a little high. Temp varies, as low as 80, as high as 86 I've seen. 82 as I type. From what I've seen, temp doesn't seem to bother them, gigs in 210 are at 79 and look great. They do look extra puffy when it gets on the warmer side. Rarely feed rod's food, poor clowns. The clowns eat stuff off the walls I've seen, they're fine. I feed maybe a couple times a week lately. I try feeding every day, but sometimes/most times doesn't work out. Lugols iodine is added, maybe a drop or two a couple times a week, if I remember. Only parameter I try to keep on top of is KH, the most fluctuating. I manually add mag, but don't know what level it is, only when manually dump the KH part, it looks different when it's low, like a different snow storm. I aim for KH9-10 cal 400-440 mag I don't accurately know right now, but 1350-1400 I'm guessing. I use both kent mag (the cloudy stuff) and B-ionic mag.
I DON'T KNOW IT ALL. I'm still learning. This is what I've been doing and seems to be working well. There's things others may do differently and be successful.
