New dry rock always ( I have started5 tanks with it) goes from white to brown to green to purple/blue/ pink or red. The reason you are seeing this is your rock is not smothered by the gha anymore. This is a good thing. You will see

Hehe, cool !!

2nd la, and when I clean it couple days ago....Oh No!
Noticed most of the water spray towards the box instead of the screen!
Growth is very thin I think because of that?



Also very brown/yellow. But where the screen sticks into the pipe is green. Why?

I've now put a plastic wrap around it and noticed the growth is much faster. Got more that above growth in just 2 days. But color still more or less the same.
Any suggestions?

Because it's in the slot and protected from light. The rest is over-lit.

Ok...so try cut down the light from 18 hours to 12?
I've tried more flow, but the spray becomes stronger and it even pushes the plastic wrap away from the screen.

Try inserting the screen fully into the slot, looks like your screen is sort of dangling below the slot.

Yeah, I only have it inserted maybe 3mm into the slot only.
Will try that along with less hours after cleaning this weekend.

3rd week. Cut down light to 12 hours, seems a little more green and still very slimy. Just wait or cut down light further?
Now inserted the screen fully into the slot, see if the spray gets better after a few days as it is always good after cleaning.

Could probably let it grow more days. Seems kind of big for the feeding.

Right, would be too big according to your feeding/screen size guideline.
I was thinking using a larger screen would help clean up rock leaching and whatever bad things left in the water since day 1 faster.
What I have in mind is when all rocks are clear from gha and I don't need to clean the glass every other day, then it is time to cut down the screen size to match the feeding.
Does that make sense or it won't work this way?

Too much surface area allows the algae to spread and not grow thick 3D green which filters better than what you've got there. Essentially, cutting the screen down to feeding is actually going to speed up exactly what you're trying to do.
