Innovative Marine 20g lagoon - part

[awong]

Hello all,
any IM 20g lagoon tank owner, would you be able to provide me info size of 90 degree elbows for the return pump? I just pick up free IM 20g but it doesn't have any plumping part such as elbows and return nozzles. any suggestion greatly appreciated.

But if you measure the hole I'll bet you can find a loc-line fitting or even a nylon thing at the hardware store.

It looks like they just shove a 1/2" loc-line onto that.
