Hi all,

I am losing the war badly. Every week, I am aggressive and have tried so much, but I suspect the root cause is the macro algae I have in my tank.
After removing all of it practically to a hospital tank, things have moderately improved (but still not great).

During my Display Tank weekly water change, I am using a toothbrush to scrub the live rock (all the while my tube doing the water change is siphoning the spores or whatever that dislodge as much as possible), but sadly 3 days later most of the rock is covered and by day 7 there are long strands. It's frustrating. The sand is slightly covered in green waving hairs. Btw the water params seem to be fine, I've even had another person help me check all the params and they also said it's fine.

Anyway, my question is this - my hospital tank has just tons of macro in it right now, covered with long waving strands of green algae. It's brutal. Pulling it off barely helps, and aggressively doing it just rips up the macroalgae.

Instead, I wanted to ask if this plan is good:
In the hospital tank, can I use some sort of chemical cleaner to get rid of the green algae, or will that also kill my macro algae? there is nothing else in the QT, so that might be an option?

Regarding the display tank
If I just constantly put more macro algae, rocks, etc, in the QT, chemically treat it, then put it back in the display tank, could that work? Not sure how to tackle the rest of it, but regular cleaning isn't helping.

I put about 6 turbo snails in the tank, and for a few weeks they were cleaning the glass, but the past 2 weeks I haven't seen any of them which is also odd.
I'm at the point where nothing seems to be working. The rocks are constantly getting covered and unsure what to do.

THANK YOU!

Lighting, intensity and photo period time?
Nitrates and Phosphates?
Age of tank?
Type of tank and filtration?
Water replacement source?


You will eventually prevail. :-)

Algae, coral and plants grow from light and fertilizer (phosphate,nitrogen and potassium)

Take the plants out and the rocks and scrap off the algae and then scrub the area with a toothbrush and hydrogen peroxide.

When you are done removing the algae do a 100% water change and keep the photo period to 8 hours max and report back with the results.

if I scrub the macros, they kinda break up though. Could I do a chemical approach to the QT? Or would that hurt the macros?

I'm using Amazon product and what happens is after a few weeks the sponge filter gets so gunky with green algae that it causes the water levels to rise in the filter, and the dirty water starts back spilling into the tank! Have you seen something like that before?

The params are fine and the tank is like 1.5 years old.

Unfortunately I can't view the image?
You're going to have to clean the filter media more often.
Nitrate and phosphate values?
Have you tried any phosphate removing agents like Chempure?
Nail down specific type of algae first. See resources.https://www.melevsreef.com/creatures/algae-and-plants
