Coralline Algae = Good Brown Algae = BAD

[americanbambam]

Hoping for some pro tips on here.

I recently started using Purple Up because I introduced some coralline algea into my DT, which I love BTW, problem is I've been leaving my lights on longer to account for my good algae growth but the nasty brown algae is growing too.

questions - is it bad for my "good" algae and how can I stop the brown but keep my purple growing?

Regards
Bradley

I wouldn't use anything for the coraline,cut your lights back to where they were,water changes is all you need unless their is something in your tank using up some elements of the water.To help spread the coraline just scrap some off the rock so it will spread and attach elsewhere.

correct - - - - -

[craig_will2513]

so scraping it from the rock wont hurt/damage it or anything

[francis]

that is correct, will grow back and spread

Also if you can turn off return pump and leave just power heads on so the coraline doesn't get filtered out. Do this for a couple hours. Good luck!
