Marlineland 75g CornerFlo Loc-Line nozzle size?

[KGNickl]

Does anyone know what size loc-line fittings a Marineland 75g CornerFlo aquarium comes with? I'm not sure if its 1/2", 3/4", or a mix of both. I'm mainly wondering what size the two nozzles are? I posted the question on Marlineland are they responded with an answer of 1" which I'm guessing is the PVC that the loc-line connects to. Then I called support they said they did not know and none of the documentation says. Hoping someone knows.

If I remember correctly on my 75 it was 3/4. It does not work with loc-line though its smaller. The pieces will not snap onto loc-line. I replaced mine with a 3/4 Y and 2, 3/4 nozzles.
