Great little filter
Great little filter. Cleared the water really well and probably saved my fish whilst I get their new, bigger tank set up

Not suitable for goldfish fry as advertised
I lost goldfish fry into to the filter so it’s not suitable

Works surprisingly well
Used this to cycle my shrimp jar and was surprised how well it works; within 24hrs it had cleared all the brown water from the jar (tannins from the driftwood). Nice and quiet. Only downside it that I wasn’t able to reduce the amount of bubbles with the tool provided; it’s all or nothing
