ISTA turbo CO2 Reactor Diffuser 12/16mm External for aquarium plants Atomizer ph

Very efficient!! extremely pleased with this product. reactors are far superior to diffusers or atomizers

Not very impressed. I was expecting something a lot sturdy that actually stays on the tank. This tilted constantly after fixing all the time. Fin ally I gave up. Noisy and didn't fill. Was expecting it to fill up with water but no such luck. I'll stick with my ceramic for now.

Have it for years, works brilliant.Works well with high pressure co2 bottles as well as the 2 component co2 generators. I find that I am not having to adjust the pressure/bubble count as often as I had to with those atomizers. I also find that is more forgiving connection security wise as the atomizer is fed with low pressure co2 unlike atomizers that are fed fairly high pressure and therefore perfectly tight connections are a must on them.The only complaint I have is the Co2 nozzle feels very weak therefore care must be taken when installing or removing the pipe from it, and yes it os noisy but my kids are more noisy.

I have a Hydor Prime 10 External Filter and I added this co2 reactor to the outlet pipe. The " patented impeller" hardly moves! Also the water flow is greatly reduced.I am sending this back
