    Good experience using with citric acid DIY
  

*by D***G on Reviewed in the United States 🇺🇸 on October 28, 2016*

Bought 2 as add on items, paid $3 bucks for the first and $6 for the second. This was a upgrade from using tree branches, which works extremely well. Search YouTube( worlds best and cheapest cO2 diffuser) if you are curious. The first is working awesome. Never seen my bubble counter go so slow and my drop checher nice and green or yellow. My diy solutions going to last forever.The 2nd. Well I tried that rubber black one from Amazon, Fluval Im pretty sure. It does work with citric acid but I was flying through my solution. But now that I,ve switch to this one and my bubble counter is still cruising I think I probably got an issue somewhere else in my 2nd DIY setup. Check valve holding up the pressure or leaking or a leak in the bubble counter or something.No experience with the yeast method. If that's what you use. Check out the citric acid/ baking soda method. There's a kit on amazon or check out DIY King on YouTube. Happy fish and plant keeping and whatever other creatures and organisms you might have.

    You Got Into High Tech Tanks And Thought You'd Get By With Cheap Parts? Muahahahaha!
  

*by J***. on Reviewed in the United States 🇺🇸 on August 9, 2017*

So you're new to C02 injection and don't wanna pay 25 bucks for a high quality diffuser? Same here. In a nutshell, this is an OK diffuser. You'll definitely have wasted 50% or more of C02 in the form of bigger bubbles but there also is a steady stream of micro bubbles. I need to run 4-5 bubbles per second just to keep my 20 Long at proper C02 levels.  C02 is cheap so I don't really care. The only real issue here is the noise of the diffuser making the larger bubbles, coming thru as a "fizzing" sound. Not normally an issue but it's in my bedroom so it can be quite annoying when working.My honest recommendation? If you're actually strapped for cash  I guess this would suffice. If you have the cash but are a cheap-skate, just buy the nice one and stop whining about the expense of the hobby. I thought I could get away cheap too, and now I'm writing this review....

*by R***N on Reviewed in the United States 🇺🇸 on May 27, 2019*

It's made of glass,  unsurprisingly if you accidentally pull the suction cup off the glass to forcefully and hit the side of the tank...it can break.Otherwise it's beautiful and worked well for a short period of time.  I think it might possibly have stood up to punishment better so dropped a star...  but its still good value as long as you remember its FRAGILE.
