The ammonia looks very high, so do not add any extra. Eventually the microbes will get to work, but I do wonder if your Dr. Tims bottle got frozen and the bacteria perished? Even if that is the case, these microbes will eventually bloom and the tank will cycle. Elevating the temperature can speed up microbial colonization, 80F.

Thanks for the reply I’m in no rush will test again tomorrow

Just to add something, remember that ammonia levels that are too high can stall a cycle. It's a big poopy pants situation. And hey!!! Congrats on the new tank!

I'm jealous. I'm retiring in a few days and was going to start up a 204g tank. Then I thought, 'You're gonna travel for weeks at a time!'. So no joy here! I'll probably start up a 40g FO and keep it simple. The neighbor can feed them!

I wouldn't add more ammonia, just let it do its thing. 6 Days isn't anything to worry about yet, a fish-less cycle like this often takes 3-4 weeks to complete, so just give it some more time 🙂

I wouldn't add more ammonia, you've already got the concentration where it needs to be. Adding too much ammonia (even if Dr. Tim's instructions say so) can prolong the cycle, and lead to sky-high nitrate when it's over 🙂

What are you running your salinity at? Dr Tim’s says you can run it down to 20ppt and it would be less stress on bacteria.
This is true, but then you have to raise it back up slowly, and I'm not sure this is worth the trouble 🙂

Sump set up
You can turn your skimmer off during the cycle too. It's not a big deal either way, but most people don't run their skimmer until after the cycle 🙂
