I got the corallife gloves, and I can't feel a blamed thing wearing them, but sakes alive, I do feel a lot better (for my fishes' health) when I have to have the arm in there for an extended time while doing a gravel cleaning. A good rinsing and drying prior to dipping your arm is as good a way to go as any before you put it into your aquarium.
Do not go to the hardware store for epoxies, or even a boat store for polyester monamer and catalyst. Just get the aquarium-safe ones the online pet stores sell.
Since the bowfront is a glass aquarium, get a mag-float. It's just two plastic encapsulated magnets with felt on the outside magnet surface and velcro hooks on the submerged magnet. The piece of velcro hooks does a nice job of safely scraping away algae. They're cheap, and I've got one for each tank. My kids go a little overboard on cleaning the algae...I make sure they leave enough for the oto.
My DIY CO2 setup is a 20 oz. pop bottle (plastic; glass can break) with a tube stuck through a hole drilled through the top, and an airline splice piece jammed in. I pulled the airline through, and the splice expands the tube into the sides of the drilled hole to make an airtight seal. The outlet goes through a check valve and is aimed into the inlet on my HOT Magnum. I get a bubble every 3-6 seconds, and it gets pulled into the uplift tube to get dissolved into the outlet stream of water via the impeller. I think that Hagen counter would be better...my setup is truly a Rube Goldberg (or Heath Robinson) affair, and I got this idea from another amateur at the LFS.
To give you an idea how this small bit of sugar/yeast CO2 can do, a couple weeks of this small bubbling went by, and I finally had to remove one of my amazon swords, cut it into three root sections, trim the leaves and replant them into my big tank. Another of the swords will need pruning soon. It doesn't take much CO2, and I'm a complete amateur. Being a newbie, I'm not sure how much CO2 will harm fish. So far, so good.
