okey dokey,
I will look at putting a few posts with pictures together for a very brief build history. I say brief as I do have a thread on another forum which is a tad epic (though far from the longest or most viewed), and I know this can put a lot off
firstly what I believe in and want to achieve
after much trial and error over the last few years I have come to the conclusion you can maintain zero po4 and no3 without being aggresive with filtration, and keep the majourity of coral happy without using amino acids. What matters is you have fish in the right amounts, and you feed a variety of foods in the right amounts. not for everybodies thinking but works for me (though I am not happy at the moment in this regard, but its a work in progress)
the tank
4 tanks, display runs into a settlement tank which us next to it hidden in the alcove, then down into the refugium where I have a 3ft x 18 inch eggcrate tray 9 inch below the water surface, growing a mix of chaeto, caulerpa (mainly prolifera but a bit of racemosa snuck in! ).
the refugium is highly circulated by a 6080,6060 and 6045 tunze powerhead s to keep ditrutus from settling out, also as the algae performs better, and to provide movement for my sps frags that are in there. I dose bicarb into the flow of the 6045
lighting in the refuge is 2 x 30w led floodlight 6500k over the algae, which grows like stink (I harvest 14l every 2 weeks), and a 120w led over my frags (chinese)
then into my sump. only really my protien skimmer in here (supeemarine 250) , and occasionally a filter sock with gac and a 100ml or so of gfo which I pump water into. also my dosing solutions bar bicarb are inputted here after the skimmer. back to the dt via a waveline 10000 dc
the dt is 960l, around 100kg of reefbones mainly plates (for easy mounting as I have to place over hand).
currently I have a purple tang, yellow tang, chevron tang, foxface (do not trust him), solar, Scotts, exquisite fairy wrasse, a jewel wrasse, melarus canary and richmondi halicoeris, and a mckosker flasher wrasse, and 2 common tank bread clowns that have been with me a long time. tbh I did have 4 more wrasse but 1 jumped (my cleaner who had been with me forever and 3 more fairy 2 of which succumbed to unknown causes the other was a freeby tjat was ordered in for me at an lfs and I turned down on sight
I feed the fish 3-4 cubes of un rinsed frozen per day plus occasional flake and fines like lobster eggs or rotifers.
Though as I say I am a bit too near ulns for my liking so looking to increase fish numbers soon.
display lighting is 3 orphek atlantik which are unlensed. they provide me far more growth than t5 did
uptake of calcium carbonates is via balling classic method, which though I know is not common over the pond, simply its the use of nacl free salt to create seawater (ish) from the sodium and chloride leftovers of 2 part. Tbh its insane on a rank my size to do this over a calcium reactor! my current use is around 45 grammes of bicarb a day, concidering I am maybe 50-60% stocked, I expect this to double over time
