Hair algae/ cyano outbreak

Im having an algae/cyano outbreak, and I noticed my ro/di has a tds of. 02. Would this tds be the cause of the outbreak? All the lights are new, flow is fine in all the tanks.

 

Did you just replace the bulbs? The new "stronger" bulbs might just be causing it. Did you add anything recently? Do you have a skimmer to export nutrients? turn your lights off for like 4 days and it should die.

 

Do weekly water change and it will eventually run its course. Increased flow helps to

 

Algae problems are usually caused by aquarium water with excess nutrients like phosphate, nitrates etc. You can try and siphon out what you can to remove the algae in the short term. In the long term you may have to examine how you care for your tank. There are some commercial dry foods also contain excess nutrients and other undesirable things like nitrates, phosphates etc so I strain/rinse my fresh/frozen foods before feeding my tank. You may want to consider feeding your fish less often. Also, changing your photo period, light bulbs more flow, using RO/DI water and a high quality salt with little if any NO3, phosphates etc like Tropic Marin may help too. Adding a phosphate remover and increasing flow in your tank may help too.
