Dinos or GHA?

[cgr124]

Hello all, I’ve been battling with what thought are Dino’s for months. My nutrients, phos and Nitrates, where low so been adding Seachem phosphate and nitrate and have brought those levels up. Added copepods and ocean magik live phyto and bacteria. This just won’t go away even with manual removal. Finally tried a 72 hour blackout and just removed the covering and the attached pic is after removing the cover. Whatever it is, it has grown a bit. I thought it is osteopsis dinos but may be I’m wrong. Anyone have any ideas on what it is and how to eradicate it. Tank is about a year old. Thanks

that looks like straight up gha in the photo and while gha and dinos are competing algaes its not impossible that you could have both.
You didn't mention how large your tank is but a good way to start would be to manually remove as much gha as possible.

Thanks, appreciate the advice. this is a 30 gallon so not too big. I will manually remove. Seems like whenever I do, the next day they are back growing. Very frustrating.

its a battle for sure.
in a 30 gallon this is how i'd remove a lot of it:
I made major headway in my tank by geting a spray bottle with deluted peroxide, a brush and systematically removing the top line rocks one by one (and any accessible rock that you can remove), spraying the affected area and letting it sit for 30 seconds, scrubbing again and dunking them in RODI or water change water in a couple of stages then return the rock to the tank and repeat until they're all clean.
You might have to repeat this but it'll remove a lot of it hopefully opening the door to shifting the balance in your favor.

Its green hair algae, which consumes nitrate and phosphate much faster than corals do. So its normal to test the water and see 0-0 on the tests, its because the algae is consuming the nutrients that fast. So by dosing nitrate and phosphate you are actually feeding the algae, you will never beat the algae if you are feeding it. You should review your nutrient import vs export, and get it balanced, strip the system of all the excess nutrients that are feeding the algae. Algae also loves low flow, not sure if I see any powerheads in the picture, but increased flow does help against algae. Just my 2 cents good luck
