Good but instructions are vague

The tank itself works fine, but the included manual lacked detail on assembling the dual-core setup for beginners. Had to watch online videos to figure it out. Once set up, it performs well.

Essential for my darkroom workflow

As someone who shoots mostly 120 film, the optimized washing tool is a game changer. It uses less water and time. The build quality feels sturdy and durable.

Perfect alternative to expensive brands

I was hesitant to try a compatible tank, but this works flawlessly with my existing reels. The dual-core design is great for batch processing 35mm rolls. No light leaks detected after five development sessions.

Best purchase for film photography

I love that I can develop two rolls at once without buying a massive tank. The plastic feels high quality and easy to clean. No staining from developer chemicals so far.

Great value, minor fit issue

Overall excellent product for the price. The washing feature really does speed up the process. I found the lid slightly tighter than my old Paterson tank, requiring a bit more force to seal, but it holds well.

Leak-proof and reliable

Used this for C-41 color processing which requires precise temperature control. The tank maintained temperature well and showed zero leaks during inversion agitation. Highly recommended.

5 FAQ

Q: Does this tank come with the spiral reels included?

A: No, this listing is for the tank body and lid only. Reels are sold separately to allow you to choose between center-loading or end-loading styles based on your preference.

Q: Does the dual-core system work if I only want to develop one roll?

A: Yes, absolutely. You can install just one reel in the dual-core tank. Just ensure the empty side is balanced or follow the manual's guidance for single-roll agitation to prevent uneven development.

Q: Can I use this for developing sheet film?

A: This specific model is designed for roll films (135 and 120 formats). For sheet film, you would need a dedicated sheet film holder or a different tank configuration.

Q: Is the plastic resistant to bleach-based cleaners?

A: While the tank is chemical-resistant to standard developers, fixers, and stop baths, we recommend avoiding harsh bleach-based cleaners as they may degrade the plastic over time. Mild soap and water are best.

Q: What is the minimum volume of chemistry required for one 35mm roll?

A: For a single 35mm roll in this tank, you typically need around 300ml of solution to ensure the film is fully submerged and agitated properly.
