No, I would not recommend this.

Does not come with Soleniod

Not made for Reef Tanks. MarineDepot was more than helpful on the return.

A Must Buy

I replaced two CO2 regulators with these and all I can say is, these are excellent. They come with a proper sealing ring, no wrenches, hand tight and the control is unprecedented. Definitely, great quality and I would highly recommend using them.

CO2 regulator

The regulator is doing great so far. Just had it running for one week. It adjust easy so the you can get the exact amount of CO2 that you want. the needle value seems sturdy enough to last for years. Beat CO2 regulator that I have ever owned.

Great Reg.

The things you look for in a regulator are solid construction, reliable and readable gauges, and precise gas control. This regulator has all those attributes. It is a solid unit well worth the investment for any experience level. Sometimes simplicity in design is the best antidote to failures and this product hits that mark and resonates. It simply works and beautifully. Tunze GmbH product complete with German quality control; it shows! Highly recommended.
