I have had my 55 planted going for a couple of years. The first year and a half it was beautiful with no algae and crystal clear water. Starting a few months back i was starting to get algae on the amazon swords and tank decorations. I posted some pics then And was advised to up my dosing schedule of flourish because the plants new leaves were a whitish coloration. And was told that when the growth on the plants started again the algae would die off. i was also advised to lower my lighting schedule from 2 6 hours periods to no more than 10 hours total. So I did all that and i am now dosing twice a week for the whole tank volume plus a little. i replaced both PC bulbs with new 6500k units. The old ones were 6500k as well. i am still on the same schedule for my yeast generated co2 and it is 2 -2 liters going to a power head for diffusion. And I have always mixed up new in one bottled every 2weeks.-----------------------------------------------So now my problem is cloudy water. The water has been cloudy for the last few weeks. The ammonia is zero the nitrites are zero and the nitrates are 20ppm. It is not a white cloudy like a ammonia spike but not a green cloudy like a algae bloom either. I have noticed that the algae is slowly going away. And most of it has turned from beard algae to a reddish brown color. i was on a Water change schedule of 50% once a week. And since the cloudiness has started i have been doing 50% 2-3 times a week with gravel vac's at every WC. After a WC the water looks a little better then 24hrs later its the same. ---------------------------------------If anyone has any advice to help this cloudy water problem it is greatly appreciated Thanks alot
