Once the ammonia is zero I'd start to add pods. FWIW, when I cycled my 750xxl I went lights off for several months and just started adding pods and a small CUC. Saved me loads of heartache with nuisance algae.It is algae on the glass but not hair algae I think maybe regular " green algae" I will keep my lights off then and let everything stabilize especially ammonia. One last question would it be a good idea to add some pods at the same time to establish a better ecosystem or should that wait to after ammonia is stabilized ?
