1. over my 24" x 24" 60 gallon cube, i used to run a single 400w radium with two 24w actinic+ T5 supplements. I ran the halide for 10 hours, the T5s for close to 14 hours. the entire fixture hung approximately 10 inches off my water. the anemones are about 4 inches below the waters surface just off from the center of the aquarium.
i currently have two Sols about 10 inches over my system as of last week, the day light setting is running at about 40% right now, but over the next month and a half i will raise this to 100%, along with the other royal blue and blue settings.
in a separate system, i have a magnifica under a single 175w running a 20k ushio lamp.this lamp is 6 inches above water, with the anemone at the water line.
2. in my 60 gallon, i do not have any refugium, biopellets or dosing. even with three large anemones, some heavy feeding and large fish....i do not ever have nitrates above 0.
3. in my garage system, i probably have nitrates between 0 and 5. i havent tested in months. i have a 40 gallon refugium, and biopellets. i also dump a tremendous amount of food into this system.
4. i maintain magnesium in both systems and occasionally dose potassium and strontium with infrequency and non specific amounts.
5. salinity, alkalinity, calcium, magnesium, phosphates, nitrates, temperature
6. i keep my salinity at 1.025, which i believe is 35
7. salinity 1.025
nitrates 0
phosphates .03 -.05
temperature 78 - 81
pH 7.8 - 8.1
kh 8 - 9
ca 500
mag 1400
8. my systems are clownfish/anemone devoted. however my 60 gallon is also highly sps devoted as well.
9. the only anemones that seem to have problems with heteractis magnifica is carpet anemones. i do not do well with them. sebaes, quadricolors tend to do just fine.
10. i feel infrequently, usually raw prawns from the grocery store. every few weeks.
11. i do not quarantine, but have experienced the negative effects of taking in risky specimens with otherwise healthy magnificas. will most likely attempt quarantine proceedures of some sort going forward.
12. no antibiotics used, but have a list going of ones i would like to experiment with.
hope this helps!
