i have practicly a newly set up 2 foot tank, probably like 3 weeks or so now and ive noticed small fuzz algea growing on some of my java ferns. my current photo period was 12 hours and ive cut it back to 10 now. however it seems the problem is only going to get worse, the thing is that none of my other plants have it, its only on the java. asside from cutting back on lighting some more what else can i do? thank you
