ostrow, i'm using Rowa in a deltec 509 fluid reactor with slow flow. phos and silicates didn't even register on salifert kits.
i've been rotating 3 cups of kent reef carbon every 3-4 days w/o results
jecco, i'm sorry to hear about your restart...but often its a blessing in disguise!
theyeg2, MH's are almost 1year old but i only run them 2-3hrs/day. i change the vhos (6hrs/day) every 8months and the T5s yearly.
i'm currently blacking out the tank for at least 60hrs. then will do a 20% water change and am going to try a product called AZ NO3 to lower my nitrates from the current 5-10ppm. after the blackout, will slowly ramp lighting up in .5hr increments every other day.
