290G Peninsula Tank

[lastlight]

Other than the cyano your tank looks clear so congrats on that. I faced similar issues but not for that long thankfully. My rocks were so covered within a week of carefully brushing/cutting/plucking that I could barely see them. Vibrant was also what turned things around in my case. I have only done single, small doses maybe once every 2 months since and things are continuing to do ok for me. Looking forward to more updates =)
