Hi guys
Some info on tank..it has been through some issues a month ago with temperature fluctuations etc due to broken fan failing to keep temperature down, where then after few days of heat a cold day came and new fan stayed on dropping temp down while at work..then two weeks later have electricity supply cut for a day due to maintenance yada yada yada
I am having issues with stn from bases of certain acropora..mostly happening with Milliporas and certain acroporas.tricolour secale, birdsnest and montis are fine..can the carbon dosing be causing it as the temp has been stable at 26degrees for last three weeks and all affected corals from temp incident died and were removed.
info on tank...4 foot tank with 85w intellisun led units and 54w t5s
Salinity: 35 ppm
Calcium 400
Kh: 7
PH: 8
Magnesium: 1400
Nitrate: 15 (its high as tank has a lot of fish which I plan on removing once I get a chance)
Phosphate: 0.5
Potassium : 400
doing diy through grotec doser so parameters are pretty stable as I have been monitoring every few days for last three weeks.
can the carbon dosing be causing the STN? I have a little biocubes in sump which are being depleted so I supplemented with VSV dosing at 0.2ml per 20gallons last two week...then it seems the stn got worse
any idea whether the vsv is causing it and what I can do to stop the stn..I do like the vsv dosing as its pretty flexible in terms of maintaining nutrient levels once I reach desired nutrient levels
