Hi guys, I googled it but unsuccessfull to find anything on the net about the hole sizes and fitting that go with them. I have acquired this glass aquarium from a friend and there are two 54mm holes on the side. I need to use one of them and the other will be plugged. What diameter fitting I should buy?

if you're talking about a tank fitting... maybe something like this one will do the trick. http://www.bunnings.com.au/holman-50mm- ... g_p4813626 Take a tape measure to your favourite hardware or plumbing store and if the external diameter of the pipe is bigger than about 52 mm, get the 40 mm tank fitting. |

If you are not too worried about aesthetics try anything in the 50mm threaded - PVC or nylon. In nylon the fittings get quite expensive as the Bunnings link shows. PVC male threaded with a screw end cap and some rubber as a grommet might work. If you know someone with a 3D printer you may be able to print something up similar like threaded plug or a big roof bolt with large head (and put rubber on it). I suspect that is where the future might lay with some of these questions  $70 for a fitting suddenly makes 3D printing consumables attractive. |

Thanks very much guys. I pulled my caliper from my tool box and head to the Bunnings. 25mm tank access coupler fit the bill. The lip around it wider than 54mm so it will nicely plug the hole on the side of the aquarium.

Just dont bump it too hard- as the pipe can move around enough in the hole for the flange to not cover your 54mm hole- leaving a 1mm gap. (53mm from one side of the thread to the opposite outside of the flange/washer) A 32 or 40mm tank flange may have been a bit safer size, but you'll be ok with 25mm if it cant be bumped out of place. |

Thanks Gunagulla. I was going to go bigger but there isn't much space at the bottom of the aquarium to take a wider flange; the hole is very close to the bottom. This setup will sit at my deck and no kids will be allowed near it. :-) |

I've had a similar problem before. I cut off the offending portion of the flange with a hacksaw. Sent from my Nexus 6P using Tapatalk |

Yep that works well, I cut a flat on one side of a 50mm flange for the water inlet at the top of my tank, as the tank wall becomes irregular on the inside and it wouldn't seal properly when it was round. |

Thanks guys. Thought about cutting it but I think I will use a little bit of silicon to seal things up to cut the maintenance when I fill and populate it later. |
