Hello everyone: I need some assistance in choosing a material to make a light diffuser for my Fluval Spec 5. I use a 16" Finnex Fugeray Planted Plus light and it just puts out way too strong a PAR for that tank and the plants I have. Consequently I have been fighting algal bloom for several months and have grown tired of pulling out my spiderwood, washing it off, replanting my swords and hair grass, using algaefix literally every other week, turning over the substrate (eco-complete). Hoping a diffuser layer will bring down the PAR levels enough to let my dwarf hair grass grow, and to replant new flame moss and still allow my swords enough light. Ideas?
