thoughts on adding more tetra safe start

I've used dr tim's one and only in the past with success to speed fishless cycles but have always had to order it online. for the fishless cycle in my 40g this time around I decided to try tetra safe start and it appears to be doing a pretty good job.

I used the 8.45oz bottle (for up to 100g) and added last wednesday night. I put ammonia up around 4ppm, checked the tank again today and ammonia is around 2ppm and nitrite is at .5ppm. so, clearing a fairly robust amount of ammonia after only 4 or so days.

Out of curiosity, how much of an impact do you all think another bottle would have, either the 3.38oz (up to 40g) or another 8.45oz bottle? this is half curiosity and half impatience.

no, those are all long gone, had to get rid of them when I went to college

well, you should trust this stuff!!!

my tank is now clearing ammonia after 5 days. I expect a full cycle by thursday or friday, which is super exciting!

I don't ever plan to do a "pure" fishless cycle ever again. waiting 3+ weeks (how long it took me to do a fishless cycle last time) is just not worth it for me. this stuff is easy to find and not too expensive. I'd even be comfortable doing a fish-in cycle using this; actually I almost did but the guy at my favorite LFS talked me out of it. he echoed all the reasons why I was hesitant to do a fish-in cycle and convinced me. plus I wasnt sure I wanted to keep hardy cycle fish in my final stocking.
