I am running a fishless cycle. Tank set up with 3/4ths new water and have slowly added water from cycled tanks when doing water changes on the other tanks.
Gravel is mostly new except for a small area(front to back of tank) where gravel was moved from an established tank
Filters are described in signature. Uv is not currently running
Plants are in the tank with a couple of hitchhiking regular pond type snails (small)
Water was cloudy this week but has cleared
Params
Ammonia - has remained and is still 0
Nitrites - at a constant 0
Nitrates - at a constant 20
ph - remained at a constant 7.6
Cannot find pure ammonia in local store (most have cloudy ammonia that suds up)
I am now seeing more growth of green algea on the transfered gravel and a bit on one of the new decorative ornaments...... Does this mean, with the algea growth, that my tank is safe to start transfering my goldfish?
