Red Brownish Algae

[Pat-O]

Kinda Looks like Dinoflagellates to me (going by the bubbles). More often than not an excess of nitrates and/or phosphates is the problem. A few things I have done in the past to control outbreaks

• Carbon as a scrubber can help, run actively or passively. I recommend almost everyone use carbon in there sump; run passively at least and changed at regular intervals. It improves water clarity as well as quality.
• Raised pH can eliminate the problem but perhaps only short term without other issues being addressed.
• A refugium, if space allows, can go a long way in counteracting dino's as well as many other BAB's that are commonly discussed.
• Nitrate sponges or some other NO3 remover can be affective.
• Granular Ferric Oxide (GFO) can be used (with caution) to remove phosphates

Most of the algae is turning green now which I am very happy about but the piece with the bubbles has gotten a little worse and seems to have some pieces stringing now. Not sure if its the stuff your talking about but do you think I should actively treat for it. I already have carbon in my filter and I am currently raising a low ph.

I would siphon it out during water changes. With the measures you are already taking, water changes and the tank maturing some it should disappear for you I would think.
