I have a newish system--an upgrade from 125g to approx 220g total water (depending on calculators). Almost 5.5 mo old. RS 3xl 900, 240 total vol. Some old rock with corals on them, some added to sump, and the rest new rock (caribsea & real reef). Bottled bacteria and no cycle. Very low no3 and po4 for the first few months and great coral growth. Used hanna and api. Then realized after I got the hanna no3 I had higher no3 than I thought-20-40 instead of 5-10. Algae started.
Didn't want to have to resort to chemicals, but I cannot get rid of the algae. No3 holding under 20. Mostly under 10. PO 4 under .18-usually around .08-.09. Some of the algae seems to be acting like an algae scrubber. Long and waving in the strong flow so am thinking the algae in tank affecting or hiding my correct numbers.

Ca 416 Mg 1549 Alk 8.5
Hanna
No3 .9 PO4 .08
No water changes. Have DOS to hook up awc but tank has been low nutrients--Po 4 sometimes bottoms out, No3 under 5 or even lower, so haven't done any. Have UV running about 45% of my dc 10000 pump.
I dose alk/ca/mg and nopox. Manually dose phyto (100-150ml day), and trace colors. Neophose when needed and MB7 weekly or bi-weekly. Was using vibrant as well.
Have a double sump. Do have trouble with flow in 2nd sump. Using a powerhead even though that might not be good for pods (pushing water from front section into back refugium section. So its better now-no film on top now
I'm planning to dose reef flux as corals are now in jeopardy of the algae. Rocks are such I cannot remove to scrub
I have 2 bottles of reef flux , each treats 100 gal. It also says to use 10 capsules for 100 gal system, regardless of rock, so my actual system is 240 but the sump of course is not full to top or the display. If I take rock and sand out of calculation, I get about 226g.
That means 20 capsules for 200 gal.
Each capsule treats 10 gal so add 2 or 3 extra.
Should I add more bottle bacteria while this is in use? Continue with MB 7? Stopped using vibrant
Should I add air stones to the sump or display? I'll point returns a bit high and turn up the 2 RS 45's to keep good surface agitation.
I've used before in old tank. Nervous using in new!
