My new betta is showing no signs of being sick, but when you agitate the marble gravel at the bottom of his tank, there's little mucus-looking things, about 3-4 mm long at the very most, that float around. I siphoned a bunch of them out. Is that excess slime coat or something to be worried about? I don't see any on the fish and I've found this stuff in the water the last 2-3 times I've cleaned his tank. It settles to the bottom of the tank really quickly when the water stops moving. It doesn't really bother me, but I want to make sure it's not bad for the fish.

I recommend that you add 100% water changes to your schedule, at least every other water change. 50% every 2-3 days is a good start, but in uncycled tanks, you have to do 100%s in order to remove all the nastiness from the gravel and the ammonia residue from other parts of the tank. If you think about it, if you do one 50% change today and one 50% change tomorrow, sure, that adds up to 100, but that doesn't mean the fish ever has 100% clean water. There is inevitably some of the old dirty water left plus whatever the fish contributed to it in the meantime, so over time, these partial changes become less and less effective. Only filtered, cycled tanks can thrive on partial changes alone, and 1.5G is simply too small to be set up that way.

Sometimes excess slime coat can occur as a reaction to unfavorable water conditions, especially if your additives also "promote" slime coat growth.

Ok, that's a pretty easy thing to do. Does a 100% change weekly plus 2 50% in between sound like a good schedule?

You could try it. To be on the safe side, though, test your water for the next couple of weeks to be sure it's truly effective at keeping your water as clean as it should be. If you don't own a reliable liquid master kit, you can take a water sample to the pet store and have it tested free of charge.
