I would start by reducing your lighting to 8 hours max, and doing more water changes. Also, please provide your Nitrate and Phosphate levels. 30% every 2 weeks is really pretty light for water changes. Remember, your filters only house beneficial bacteria and mulm. They do not remove nitrates from your tank. That is what water changes are for. If you have high lighting, you are walking a dangerous line with having an algae explosion.
Edit: just noticed you are not running CO2. You need to lower your light levels and perform larger, more frequent water changes.
