Recently I was thinking what type of food to feed my opae then I remembered they eat algae so I took small pebbles and put in brackish water and put out in the sun few jars to culture. How long should I expect before algae start growing. During the day it has sunlight and night there is led ceiling light on whole night so they get quite alot of light.

you should have added the word Algae ! I don't want a knock on the door at 04:00 ! :ninja:
Just how I do it, but it seems to work, 2 gallon tank on south facing window sill filled with fresh water from the 70 gallon Front room Amano Shrimp tank, water change, then added a few drops of 'baby bio' plant food for more Nitrate seeded with a small scrape of Algae from the Amano tank less than a week for Algae to start growing on tank sides

cut some pieces of scrap glass drilled a hole in hung from a stick above the tank with string

I also hung a Limestone rock in, when this had Algae growing on it, about a week, I transfered it to a jar of SG 1.010 RO Water on the windowsill for my upstairs Opae ula tank

I don't think Algae self seeds in brackish water but continues to grow when added, here's the jar today I might add another piece of Limestone rock

the pieces of glass are for one at a time into the Amano shrimp tank

this is only my observation you can leave a jar of SG 1.010 and a jar of fresh water in the sun and the fresh water will start to go green (algae) after a few days but the SG 1.010 will still be clear, maybe ? the algae self seeding spores ? need fresh water to start to grow. I don't live by the sea so not much chance of marine algae spores ?
anyway I already had algae growing in a fresh water tank and adding a scrape to both jars saw it start to grow straight away. I did add a few drops of plant food to the water in the jars to add some Nitrate :grin3:
here's how I started back in February
