Ha! Someone else from IL! Hey there! xD
Anywho, I agree about the pellets. Sounds like a good amount. Usually for a normal-sized, healthy adult male(as females can tend to be smaller, but thats not always the case!)about 2-3 pellets twice sounds about right. With a smaller-sized formula, like New Life Spectrum, you could get away with 2-4 probably, but I'd say 2-3 is a good general rule to stick with with most pellet brands and most bettas. ;)
As far as the conditioner goes...for just general conditioner, plain old Seachem Prime is the best stuff. Its going to remove just about everything potentially harmful in the water, including heavy metals(which if I recall correctly most other conditioner brands don't address) and it will also detoxify ammonia(again something most other conditioner brands don't do)for I believe 24-48 hours which can be very helpful if you're going through a fish-in cycle or if you have a bit of ammonia in your tap water. The big thing about Prime for me is though, besides the quality, is that its also more concentrated, meaning you need less of it to treat the same amount of water as other brands, meaning you use less and need to buy less of it over time.
It does have a bit of a smell, but that disappears once its in the water and so long as you keep it capped when you're not using it personally I've never had much of a problem with it. Its really some pretty good stuff, worth the momentary smell if you ask me.
From my understanding, TetraAqua isn't a horrible conditioner(nothing in particular makes the BettaSafe any different from the regular stuff as far as I know....just a marketing ploy)but its not really as concentrated as Prime....you'd be using and buying lots more of it.
Stress-coat does condition the water as well I think, though personally I wouldn't trust it as a sole conditioner. Mainly its a good additive for stressed, sick, or healing fish to help promote a healthy slime coat, supposedly reduce stress and promote healing. I've never personally used it myself, but I've read about other members having used it with good results.
Hope this helps some!
