Tank Troubles

Here are the problems I am encountering and hoping for help or guidance.
46 gallon bow front up and running 6-8 weeks. CF lighting 10 hours duration. One 96 watt bulb on for 10 hours, the second 96 watt bulb on for 2 hours for a noon day blast. ADA aqua soil substrate. Well water with a tap ph 6.8, KH 7degrees. Pressure C02 with a drop checker running in the green zone. I know it works as when I do water changes it will be in the blue for a period of time before retuning to green color. Magnum canister filter with ceramic bio spheres. I have installed a surface skimmer on the inlet side of the filter.

Here is the issues. From the start I have been EI dosing with Greg Watson dry ferts. Doing 50-70% water changes every week. The first 2 weeks the tank exploded with new growth. Did all pruning and cleaning prior to water change.

The last 3-4 weeks a major out break of hair algae. And now very limited growth on any plants. What new growth appears gets coverd with hair algae. Also there is a bronze to rusty color sediment that attaches to all leaves. This can easily be removed rubbing the leaves but returns within a day to 36 hours. I have been in contact with Greg Watson and he referred me to this area for big gun help.

My nitrates were well over the 40-60 ppm range while still doing major water changes at least weekly or every 3 days. I continue dosing CSM+B, magnesium sulfate, along with mono potassium phosphate. I have not added any potassium nitrate as my nitrates seem to hover in the 5-10 ppm range. The tank is not attractive to look at and the water never appears sharp and clear. It carries a yellow tint and am guessing from the tannins from the ADA substrate.

Very minor fish load: 3 ottos, 3 rainbows, 3 glow light tetras, 4 rasboras

Any and all help or suggestions are needed. I dont feel the plants are healthy enough to sustain a 3 day blackout to try to turn the algae around.

Thanks in advance for your help...Tracy
