This is a great CO2 generator
Fzone has fantastic customer support (thank you Cheryl). I was missing the white piece on my filter and they sent me a new filter. I have used an fzone regulator on a paintball tank previously, but I had a stroke, and it's no longer possible for me to go get CO2. Therefore, I looked for a CO2 generator and was happy to find that fzone had this oneBecause of my previous familiarity with using CO2, despite the horrible instructions, it was quite easy to get set up and get started.This unit came with a solenoid which works perfectly. I have it on a timer to turn on in the morning and shut off at night. I replaced the diffuser with one from clscea (stainless steel, widen hook 25cm) which works much better, especially for rimmed tanks. The supplied funnel's base is too narrow to be of real use (fzone please replace this).This unit no leaks, it's looks great, runs quietly, gives me great value for money, and I have to trim my stem plants more often now and my plants look fantasticFzone makes great products and I will buy from them again.

Excellent Product, but.....
The media could not be loaded. Just received the product this afternoon and got it up and running. At last look it is charged with about 410 psi CO2 and 60 PSI in the can, which is good. I am very happy over all with the product, but I do want to point out some serious issues with the written directions included with the system. I think they are really bad because it does not even address how to hook up the Solenoid. I figured out by intuition. The really big mistake in the instructions is the wrong material weights and water volume to mix together in the tank. That mistake cost me $16 in citric acid and sodium bicarbonate material. I had to depressurize the cylinder and empty the contents and start over. That was really bad. I have included pics of the instruction sheet and the label on top of the cylinder in yellow, which does not match steps 1 and 2 in the instructions. Also, I did end up breaking the curved glass CO2 hose connector that hangs over the rim of the tank trying to assemble it. The adjustable valve that releases C02 into the bubble counter is very very very touchy and hard to dial in because it is tight to turn and the slightest adjustment once it is open and gas is flowing will exponentially alter the bubble rate. Not a fan of the adjustable valve because it is so difficult to dial in. I tried to time 1 bbl per sec but could not exactly dial it in. Close enough I guess. Over all, for the price and what it achieves it is a good product and I do recommend it. I plan to keep it for at least 90 days to see how it performs. If I end up being dissatisfied with the system, which I do not anticipate at this point in time, I will purchase a 10LB CO2 tank from Airgas nearby and get CO2 refills going forward for about $30. I also purchased the Milwaukee 122 PH controller at Amazon to mitigate any harmful PH changes in the aquarium. It will shut off the solenoid power on the CO2 tank if the PH drops below my desired limit. Pretty cool setup over all for a relative low cost CO2 system and I'm pretty excited about it. Hope this info helps. 60 day update: refilling the cylinder because it was close to being in the Red on the C02 gauge. However, there is an issue with the PSI tank gauge. It is stuck at 50PSI but, the regulator is not even connected to the tank. I disassembled it to add the new ingredients. I tried tapping on the glass PSI gauge to get it unstuck to no avail. And of course its past the 30 day return period. See added picture.

It's a good tank.
No seal problems, all parts there, instructions are mostly good. If you dont have a scale, you'll need to do a little math. I added 13.8 Tablespoons Baking Soda, and 8.3 Tablespoons Citric Acid with my 300ML water and it seems to be working out... but again do your own math and make sure do NOT take my word for it. It's been a few weeks and my plants seem happy and my fish are alive so those measurements haven't killed my 29G just yet...Anyways, the setup seems ideal and is decent price as far as I can tell. It does the job well, and hasn't failed me yet. Seems like it's decently made so I'm happy with my purchace. Would buy from this seller again.On a final note... buy a CO2 drop checker. I did some math and figured 1 bubble per 2 seconds was good.... now I'm using 4 bubbles per 1 second. It will help you figure out how much to be adding to your tank and save you mental stress trying to guess. Just take it SLOW and figure out what rate gets your checker green fastest and keeps it green without going into the yellow (danger) zone.

Wonderful while it lasted.
I really liked this product for my tank. Despite the lack of instructions it was simple to set up and forget. The solenoid is still going strong, the whole system is very quiet, but I consider the diffuser to be subpar and replaced it. It lasted about 5 weeks for me on each charge. Unfortunately, almost a year to the day it failed me. A fresh charge only lasted 10 days. The next charge only lasted 5 days. I unscrewed and cleaned and checked each gasket and connection and did another charge this morning. I can already see the pressure has gone down significantly.Overall I think it's a great system as long as it works, but I'm not interested in having to buy a new system every single year.EDIT: I actually wanted to come back and bump the review up to 3 stars as I've managed to get almost a full month on a charge with a THOROUGH checking of the nuts, gaskets etc during each recharge. Too bad the solenoid failed yesterday. The wires snapped clean off the housing. It wasn't too surprising seeing as even the heat shrink tubing wasn't on properly.I don't know if I just happened to get one of the bad batches or if the company has a quality control issue, but it has soured me on buying any of the other products I was thinking of buying from them.
