green cloudy water and algea
I just set up my 55 planted about 2 and a half weeks ago. I got my big plant order in from sweet aquatics about a week into the process. Since I got them, I have been dosing flourish comp. weekly with the recommended amount. My lights are on for 10 hours a day right now. I have 2 32 watt T8 bulbs about 5 in off the water.

About 5 days ago, My water started to get really greeny cloudy and what looks like hair alga in the reef world started to grow on my plants and glass a little bit. My fish and plants are fine. The plants are growing really well.

I just reduced my light schedule down to 8 or 9 hours a day. (Its hard do tell what it is exactly on the timer)

I have been feeding little. Not even every day. So, what gives. What am I doing wrong??????

There is going to be an algae bloom early in the process. The plants are still shocked from shipment and parameter changes and aren't out competing the algae. I believe that is part of it. You said that your plants are growing well so I don't think that is the whole story. I would look into the lighting. Aside from your timed lights, does the tank receive any daylight diffuse or direct? If so I would consider keeping the blinds and curtains in the room with the tank closed or repositioning the tank. For the timed lights I would cut down to 8 hours and clean the glass and decorations that are reasonably easy to clean and monitor algae growth. If it isn't overtaking the glass or decorations after a week increase the light by 15 minutes and monitor for another week. When the algae begins to overtake the glass and decor within the week reduce by 15 minutes back to the timing when algae was manageable. I would also consider the addition of some algae eating animal if you don't have some already and your current stocking will allow it. Many snails prefer algae above all else and will actually "clean" algae off your plants. Lastly invest in a magnetic glass cleaner. Cleaning glass every 3-4 days is not out of the ordinary for a planted tank. Cleaning the algae off the glass forces your algae eaters to eat the algae on gravel, decor, and plants which cannot be easily cleaned. I hope this helps.

No I don't have any type of algea eater but I will get one. I do have 2 tiger nerites and 1 zebra nerite
