plus, your tank is only 6 weeks old. expect all kinds of weird growth on a young tank, it should clear up over time. my tank is about 6 months old and i still get random algae growth here n there.
as far as filtering goes, i run no mechanical filtration at all. only biological (live rock) and chemical (protein skimmer/refuge).
