Hello again NYC. Sorry for the late answer but I have been skiing over the weekend, and no internet.
Thank you for all your nice comments! :splitspin
I will try to answer your questions.
I had some salt aquariums many years ago, with dead white corals and some fishes. Some years ago I saw a really nice reef tank with colorful corals, and decided to start over again. I do not regret that. I did a lot of research and reading before I planned this tank. I wanted a clean setup with all the equipment hidden, and technique that would facilitate to run a reef tank. My focus is corals with a lot of fishes. As many species and colors as possible.
Technique:
The main tank is optical white glass, 12 mm thick. 160 x 75 x 65 cm (lwh).
Live rock approx 130 kg, and live sand 4-5 cm.
Circulation with some Tunze streams with single controllers hidden behind the reef.
Lighting: MH 2 x 250W 14500K 8 hrs, T5 4 x 54W blue actinic 12 hrs.
The sump. From left:
A filter with phosphate absorber (Rowaphos) and activated carbon, changed monthly. A nitrate filter with sulphur, to keep nitrate levels low despite a lot of fishes. A skimmer (AquaCare) fed with a very low dose of ozone, to keep the water crystal clear.
I also have some bulky equipment in the room behind the tank:
A turbo chalk reactor (AquaCare) with automatic control of CO2, filled with 90% calcium and 10% magnesium granulate. To maintain KH, Ca, and Mg. UV 2 x 40W, in a closed loop from the bottom of the reef. Keep my tangs healthy. Finally a chiller used during the summer.
I change 15-20% of the water every second to third week. I use reverse osmosis and keep the water in the basement. Water change is done easy with separate plumbing. Weekly I add strontium, iodine and amino acids (CombiSan). Now and then I add some bacteria. I feed the corals twice a week at night with cyclops, zoo/phytoplancton. I clean the front glass when needed. The back wall once a week. There is space behind the reef. The other equipment needs little maintenance. I think that?s all.
Chemistry: Salt 1.0245, temp 25-26 Celsius, pH 7.8-8.0, KH 9-10, Ca 420, Mg 1400, Nitrate 0, Phosphate 0.
I hope I have given you some answers, otherwise just ask.
And again thank you for your response!
Best regards,
Erik
