Iam cycling my tank 30 days ago using live bacteria since the first day .... ?????

I am still cycling my tank 30 days ago , using live bacteria product ( BACTO-ACTIVE) since the first day .., (NH3=0 NO2 >1 NO3 = 10)
... start by using fish food.
may be the live B .product is not ok ??? .... go buy another live b . product . ?????
and what about overdose , can it harm ?

 

What are your parameters? Have you tested?

 

yes its still NO2 > 1 NH3 = 0

 

You cannot really overdose with a live bacteria product in a cycling system
the tank can only accomodate a certain amount, in relation to nutrients available
the rest just dies off and becomes part of the food source for the living ones

your paramaters seem to be in order
there is no rule on how long it takes a tank to cycle some happen faster than others

the live bacteria product you have, may have been on the shelf to long, or stored badly in high temperature enviroment etc
may be that the bottle contains mostly dead bacteria and only a small proportion of live bacteria , which could explain why it has taken 4 weeks to get this far

I see no reason to go out an purchase an alternative bacteria product
at this stage I would put in a table shrimp and allow that to rot, which will help speed up and finish your cycle
