Hres the deal, 5 months ago i set up my 120 gallon dt with 150lbs marco rock and also has a 33 gallon fuge and about 25 gallons in the sump, my tank and fuge both have 2" sandbed of sugar sand from marco rocks, i have a reef octo extreme 200 skimmer with the red dragon pinwheel, 2-250w mh's 14k hamiltons and 2-54w t5 uvl super actinics. Flow is 2 reeflo darts, 1 for return powering the fuge, and reactors in the future, 1 on a closed loop.

After the tank was filled i added 2 small clownfish and 2 bottles of bio spira, tank took 7 weeks to cycle( i will never do a fish cycle again). Then i prematurely added some sps etc and the nitrates and phosphates were through the roof 3ppm phos, 20-30 nitrates.

I do a 25% water change every 2 weeks, and 4 months into it i added a dual brs gfo/carbon reactor, it dropped the phosphates to 0 on an api test kit after 2 weeks and changing out the media 3 times. my nitrates are at about 15ppm right now but am only feeding the tank 1 time a week and feed lightly at that but nitrates will not go down no matter what i do, my cheato and caluerpa in the fuge isnt doing so well, alot of clear/dead leaves on the feather caluerpa and some die off on the cheato and cant figure out why.... it should be going nuts with that high of nitrates and phosphates.

A month ago i got some free corals from a friends tank breakdown, a couple caps and an acropora of some sort thats actually going nuts, it has encrusted an entire 2"x2" rock that i glued it to, its green with red/maroon polyps so it must like the dirty water but the caps are now starting to turn a little lighter and have little polyp extension. My alk.calc, and mag are all good and dont dose anything for that yet as my water changes keep up with it. I also have a frogspawn thats doing fine but has a few large bubbles on it. i also have some anthalia thats going nuts.

Heres my plan, i did build a coil denitrator but am not going to use it so i ordered a koralin sulfur denitrator and also i am upgrading my brs dual reactor to 2-jumbo reactors, 1 for gfo and 1 for carbon, the dual reactors cartridges are just too small for 180+ gallon system, i can only safely fit about 1.25 cups of carbon and gfo in it, i know thats enough for the gfo but i like running more carbon. Also running seperate reators i can indapendantly adjust the flow in both reactors. Some day i also plan to add a frag tank to the system so the larger reactors will be better for me. Tomorrow i am going to start doing a 10% water change every other day for the next 2 weeks to try to drop the phosphates and nitrates and will also start to feed the tank 2 times per eek to raise the bacteria level and then get the sulfur denitrator up and running and also the new reactors online, after that instead of a 25% wc every 2 weeks im going to do about a 10-15% wc every week. My tds in my rodi system is at 0 and has always been 0, its a rental unit and is serviced whenever it reads above 0.

I know i did some things wrong when starting this tank, mainly adding fish to soon and also corals too soon but am trying to get back on track before everything goes to ****. Let me know if my ideas sound ok or sound like ****, im all ears and want to have a thriving reef, and im open to any suggestions.
 
I'd test some RO/DI water with the nitrate kit. It should measure zero. If not, the kit might have failed. It's possible that the GFO is starving the algae. The water changes should be fine if they're done carefully. If they don't drop the nitrate level, I suspect there's still too much food going into the tank. Can you quantify the type and amount of food being added? I might stop feeding for a few days, too, to see what happens, and perhaps do a 10% water change each of those days.
