just trying to figure out exactly what this is. i thought i had a diatom issue due to a older 250w bulb that was probably close to 2years old so i replaced the bulb and did a major glass cleaning, but i am still having a good amount of growth especially in high flow areas. also it seems to grow on the glass and over flow the best, it doesnt really grow on the rocks or other stuff. is this diatoms, or hair algea? my lighting schedule is about 8 hours of mh and 10 hours of actinics. should i cut out the lights for a few days to see what happens are there any critters that may eat the stuff well enough to control it???????????
thanks for your help
