3 day black out?
Remove all plants & decor, scrub them in a low dose of bleach/water mix, rinse well & dry completely?
Get a school of Ottos?
Be patient for the next 3 months and see if it just disappears?

Those are the options I'm debating on.
I've had it in my tanks for about 2 months and it's only getting worse.
Each tank is approximately 6 months old.
Here's my set ups in case it helps you help me...

20g high
Light: Beamswork DA FSPEC
Substrate: Black Diamond Blasting Sand
Plants: amazon sword, water sprite, green cabomba, frog bit, java ferns/moss, Anubis
Fish: male betta, 7 harlequin rasbora, 3 ghost shrimp, 3 amano shrimp, 2 otocinclus (just got them)

25g
Light: Beamswork EA
Substrate: Black Diamond Blasting Sand
Plants: 6 amazon swords, green cabomba, java ferns/moss, hornwort, dwarf sag, pennywort
Fish: dwarf gouarmi, 8 glowlight tetra, 4 RCS, 5 kuhli loach, 2 otocinclus (just got them)

Your otos will happily munch on those brown diatoms and will finish it for about a week or so.

I have 3 otos that didn't do much for my brown algae. The BN pleco took care of it in less than a week.

Diatoms actually prefer less light, so forget about the 3 day blackout. You can scrub/bleach, but they will just come back. It's never a good idea to buy a fish to solve a temporary issue, so I recommend just waiting it out. They will go away on their own.
