I have a large tank to fill (125G). The inhabitants already are a rainbow shark, a gold gourami, and three clown loaches. The other additions are planned to be two schools, one of harlequin rasboras and one of cherry barbs (10-15). How do I go about adding these schools without spiking the bio filter. I know it needs to be done weeks apart, but how many fish can I put in at a time? My readings are all good at this point....nitrites 0, ammonia 0, PH 6.8-7.0, nitrates 10.
Thanks
