Possible to cycle too long?

We started out our cycle trying to transfer some good bacteria from our old tank the filter media and a little old gravel then added ammonia. The gravel is planned to be removed to go for a more natural river rock bottom.

The ammonia was too high, ph was too high, we then switched tactics and through some quick start in and a (frozen) shrimp -just from cooking...

now the chem levels look good but high nitrates and there’s an algae and odor problem. The plan was for a water change then add our babies (15” pleco and 4” goldfish) but now I’m a little scared...

Is it *really* safe?

Maybe do a large water change and add a small bag of carbon to the filter, that might help. Is the shrimp still in there? If it is, then take it out.
How high is your nitrates right now?

How long has the tank been cycling?

The first few months of starting up a new tank after it has cycled I do at least weekly water tests and change the water if ammonia or nitrites start to register. If you keep a close eye on the water parameters and do water changes if they get high the fish should be fine. It would probably be a good idea to have some active carbon and ammonia chips on hand to provide some immediate nitrogen compound adjustment if needed.
