tank has been running for 9months got a 192 watt light last week had it on for 10 hrs a day abd i got a bad case of green algea, i was told buy the lfs to ruduce lighting to 6 hrs on the light and 8 for the blue light, my problem is removing the algea that is in the argonite, i guess the best way is to syphon it when i do water changes,i used a baster but that seemed to cover it up, any help is welcomed
