What should I get for my new betta tank/ lid for a betta tank?

I’m so excited- I found a fantastic 2 gallon fish bowl for my betta! I got it, and can’t wait to get him in it and out of his way-too-small tank I got when I bought him (it was about half a gallon, and while he has done extremely well I’m sure he’ll greatly enjoy the larger room).

Anyways, while I’m on this buying spree I’m excited to learn more about keeping a fish tank. Any useful equipment you’d suggest for a 2 gallon bowl with a wide brim would be very much so appreciated, as well as info for use and maintenance. Mainly I’m thinking of a filtration system. Currently I clean his tank every 3 days, and will probably make that every 4 when he’s transfered to the new tank. I’m hoping a filter would make that even less, but really would appreciate your opinions.

Lastly, question about a cover for his bowl. Virgil’s old tank came with a cover (it was one of those small mammal containers you can get at petsmart, so had ‘air holes’ on top) and thus I’ve never learned whether or not he’s a jumper. Are betta’s a jump risk? If they are, are there any ideas on how to jerryrig a not too unattractive lid for the bowl?

Thanks to whoever read through my rambling questions!

How much filter media in 120 Gal tank and What type??

I am starting a 120 gal. fish tank. It’s been set up for 6 weeks fishless cycling and I’m now just feeding the bacteria 2-3 Tbs few times a week until I get fish. My question is I bought a Fluval FX5 filter for it with 1 bag of pre-filter and some carbon (I realize now that I didn’t really need carbon unless I got dirty water but too late). The fish I want to get are 6 serpae tetra, 3 bala sharks, 6 angels, at least 8 cory cats, and possibly 2 rope fish several months later. Or should I get some more media before adding that many fish or go slower… There is tons of space left in filter but I’m on a tight budget to be able to afford the fish and a few more decorations. I need help figuring out time frame on which of the fish to add right away, which to wait a few weeks and when to add more media if it’s going to be needed. With the media now and 3 Tbs every day I am getting near zero ammonia, zero nitrite and I have another question on here with my NitrAte situation.
I bought this tank specific so I could finally have Bala sharks since they couldn’t go in my 30 gallon. If this is STILL too small what is a very similar looking fish that would work instead I love their coloring? How long would it take for them to grow to full size and then I could trade them back in???? I can forgo the ropes if I absolutely have to.

How do you change filter bags for fish tanks?

Hi everyone. People are telling me that I shouldn’t change the filter bag for my fish tank so that I don’t kill good bacteria. Then what exactly do I do once a month when I would normally change it? Should I change the rock – looking things inside? Or am I supposed to change the bag? Or just never touch the filter at all? Or do it less often?

Thanks a lot (also if anyone has any idea, is it safe to lower my powerhead (aquaclear 20) closer to the bottom of my 10 gallon tank? I don’t want any electrical problems.
for reply #2:
So i should change the carbon but keep the bag?
