I have a 75 gallon planted tank established at least 2 years.[censored] It's full of java ferns and a big clump pf crypts.[censored] I get what I think is cyanobacteria on the cryps and on the substrate along the front of the tank.[censored] I change 30% of the water each week and am able to remove most of it but it comes back each week.[censored] It's never gotten slimy but[censored] the water does smell.[censored] I've tried Maracyn[censored] and Ultra Life blue green algae remover.[censored] Both helped, but it still comes back.[censored] Any ideas?[censored] [censored]I run co2, use remineralized R/O water, and keep water[censored]parameters where they should be.[censored] Nitrates tend to be about 5ppm.[censored] Any suggestions?

I honestly can't see any algae on your crypts, and the left photo has some brown algae growing on your Java fern roots. Do you have a better photo?

Can you clean up the glass before taking pictures? I heard that helps.
