• Question about the penalty

Hello everyone, I would like to ask knowledgeable people about the Reef Octopus DNW-110-6520 skimmer with the OTP1000S pump. Maximum aquarium volume: 350 liters, dimensions 280x140x600 mm, external, 18 W. This is an old model, completely black; now they come in red. I'm interested if anyone has experience with this and can share how this device works, whether it is noisy or not, how well it produces foam, and if there are any nuances in its operation. Also, in the photo, I circled in red what this fitting is for.

You have posted not an old and a new model, but two completely different foamers with different operating principles. The first one is an external foamer with a foaming pump. A Schutzer is needed to supply water to the flask. The second one is a regular immersion foamer with a venturi. The foamers belong to the "quality China" segment; I haven't heard how they work.

I use one like this, it stands next to the sump, not in the water, water is supplied to the flask through this fitting using a pump.
