Caridina japonica aren't likely to help with brush algae, if that's the
problem. Neocaridina denticulata might be a better pick.
Whenever I've had black brush algae it's because I've overfertilized iron.
That's the first thing I'd check, anyway.

I'd try to cut off some ferts for a week or two and even try to raise the
CO2 to 25-30PPM.
Many of those liquid ferts are great for plants but also - yes for
algae...
What is the photo period ?
Than go back with the ferts....
How about Amano Shrimp ?

I have read lots that stresses the importance of balancing nutients,
light and C02 in a planted aquarium, but little that tells me in
simple
terms how.
My latest 55g aquarium is about a month old, is heavily planted and I
inject DIY CO2 which measures about 20ppm. My substrate is just
gravel,
into which I push fertiliser tablets, and I add a rotation of
different
liquid fertilisers according to instructions (typically once a week).
My
lighting is 2 x 4ft and 1 x 18" flouros (I think that is about 100W).
The tank is well and truly cicled. Nitrates and phospates are very
low.
The plants are growing really well - no complaints there, but I have
just begun to the first signs of green algae, and I think brush algae.
Yes - I have a variety of algae-eating fish including 5 SAEs and a
(still small) Bristlenose.
I don't think I should be getting the algae at all!, but I suspect
that
given the rate of the plants growth, I am not fertilising enough.
(That
is that there are fish-produced nutrients left over for the algae.
None of the fertiliser manufacturers state different doses depending
on
the density and growth rate of the plants. This seems wrong.
So... what are the signs to look for that indicate under (or over)
fertilisation? How much should I experiment?
Am I on the right track here?
No manufacturer should indicate dosages as it's empirical. I suggest
you
post in r.a.f.plants to draw on their greater depth of experience in
tweaking inputs to control algae.
My less-experienced suggestion would be to stop fertilizing. Everything
will stop growing (or significantly slow) when it has encountered a
trace
mineral constraint, and hopefully the algae will be affected before the
plants. Having said that, I usually control brush algae with scissors
;~) cutting off affected leaves (or scrubbing Anubius leaves), but I'm
no
expert.
