The algaes are normal growing pains with a new tank. They will subside in time if you are using RO
water. You could add some snails once the tank has properly cycled and the NH3
are no longer detectable. I would first decide on whether or not more LR
will be added. If it where me, that would be the first step. Add all the LR
you need before stocking the tank with animals. It's more than possible to cure the rock seperately later but IMO
, when you start spending money on animals, the necessary items get "missed".
