# Does the AGO work with a Paterson tank I already own?

Yes — every Paterson Super System 4 tank fits, but the funnel needs three holes drilled in its side.

**Yes. AGO works with the whole Paterson Super System 4 range, PTP114 through PTP118.**

One modification is required: the **funnel needs three holes drilled into its side** so chemistry can be introduced. Vintage Visual supplies a drilling template with every processor, and also sells a [pre-modified funnel and rear stand kit](https://shop.neoanaloglab.com/en/products/ago-modified-funnel-rear-stand-kit) if you would rather not drill. Each additional tank needs its own funnel.

Minimum chemistry volumes per tank, as published by the manufacturer:

| Tank | 110/135/120/220/127 | 4×5 / 9×12cm | 5×7 | Paper 5 (8×10) |
| --- | --- | --- | --- | --- |
| 1-reel PTP114 | 250ml | — | — | — |
| 2-reel PTP115 | 350ml | — | — | — |
| 3-reel PTP116 | 450ml | 350ml | — | — |
| 5-reel PTP117 | 650ml | 500ml | 350ml | 250ml |
| 8-reel PTP118 | 950ml | 750ml | 500ml | 400ml |

One to eight rolls per run, depending on the tank. Older Paterson tank systems and other makes such as Jobo or AP are not supported.

If you already own tanks, the [processor on its own](https://shop.neoanaloglab.com/en/products/ago-film-processor-without-tank) is the one to get; starting from scratch, the [complete set with tank](https://shop.neoanaloglab.com/en/products/ago-film-processor) includes the tank and reels.
