My shrimp won't eat algae off the plants
I have a Taiwan bee tank that spent the last 3 months cycling. It has some driftwood, UNS controsoil, and a few plants like S repens and Ludwigia [something]. During the cycling, the tank grew bits of algae, some of it obviously hair algae, but there's also green patches on the driftwood and a darker green coating on the leaves of the plants. I added shrimp a few days ago, and while they're happy zooming around and obviously eating something due to all the poop, I don't see them picking at the plants nor the green patches on the driftwood. (I know that shrimp don't like hair algae, but do like other types) The majority of time they either pick at the little substrate spheres, or pick at the relatively clean glass surface. Even though the glass is clean now, I know that if I leave it alone for a long time, it will grow this kind of combination short-hair algae / biofilm coating that easily comes off in sheets. So maybe there is a really light layer of that now.
Now given that things will rebalance over the next few weeks due to all the shrimp poop decomposing, what can I do to get the shrimp to eat the algae off the plants?
1) give up and just start H2O2 treatment?
2) add amano
3) try to grow more biofilm with Bacter AE. Maybe that will somehow combine with the algae and make the shrimp want to eat it?
Edit: Oh, and another thing: None of the shrimp are picking at the HMF sponge. I though shrimp were supposed to love that?
