Tank Nitrate levels help

[Giancarlo_Flex]

So I been cycling tank for 4 weeks, these are my levels. Was told by someone that I now have to do a 50% water change and that I could add fish after. My question is, I just changed the water rn and will refill back to 100% with r o water +salt. Can I add fish in 4 days? Will my bacteria levels be okay? Will they die off? Thanks

I personally would wait another ~week until that Nitrite hits 0.

Could you add fish now? Probably, yes.

But waiting another week would make a world of difference in terms of their potential success.

Can I add fish in 4 days?

See above. Consider adding more rock in 4 days instead :)

Will my bacteria levels be okay? Will they die off? Thanks

yeah, bacteria will be fine. I'd continue to add fish food or whatever you are currently doing to keep the cycle rolling and help build more bio-load in the tank.

Thanks will do, I only dosed 2ppm amm and added biospira 4weeks ago, haven’t done anything since

How are you checking salinity? You need more rock to sustain nitrifying bacteria in your tank. Try adding ammonia again. If it ready 0 in 24 hours or less then your tank is cycling normal.

Already 50% changed water can I still dose 1.0 amm to see if cycled?. Also haven’t had time was going to buy rocks Saturday.

Yes you can dose ammonia then check 24 hours later to see if it's 0. You already show nitrate production so you should be ok but fish need rocks to hide in at night too.
