This was beginning to be a problem about 2 weeks ago but has escalated to this. Suggestions included heavier skimming (yeah right with that skimmer

) and water changes. 25% water change done Sept 25thish, 50% water change done Oct 2, another 50% water change tonight. Water is RO/DI tests negative for phosphages.
