Do you have it running through a environmental controller? Co2 controller? You really should have one if you don't. Co2 needs to be released constantly to be effective, except for lights off. I have mine on a c.a.p. fuzzy logic Co2 controller running at 800 ppm for 12 hours in a 2x2x6 tent and I get 2 weeks. Also I keep my bottle out of my tent so I always tape up connection to try to limit leaks. Prefer to keep the tank in the tent. Hope that helps. And their is no need to ever run at 1500 ppm. A plant can only use as much Co2 as the intensity of the light allows. So save your money and trips to refill. 600-800 ppm is plenty for most grow rooms. Unless you are putting a tremendous amount of light down then adjust accordingly.

One full tank seems to run approximately 32 hours set on 'medium' output. I don't use the 'low' output but it definitely would run longer hours on this latter setting. Hope this helped

The tank is only for buffering.I think the flow should be OK to do at least one 40 G tank the day.Good unit ,Water is great

The water will not circulate through the filter it there is no power. It stuts down every 12 hours for approximately 1 min to purge any air. This is automatic. However if the canister is set lower then the water in the tank it will fill with siphon once it starts. It is by far the best filter pump combo I have ever had and would highly recommend. I love it just plug it in and forget it.

The flow is pretty fast for me, much quicker than my last Brita one. There could be something defect with yours.

It is connected to a set of 30 pound propane tanks and it is workingd good. It is using only one tank at a time. A 20 pound tank I have never tryied.

I've used it twice a day for about 6 months, hadn't noticed any reduction in performance. But don't forget to fill the water tank before turning on the unit. For some reason this caused the pump to fail.

For very short bursts it will work... to have it work continuously you will need a 10 to 20 Gal tank, but if you are doing very small projects and have some patience it will work.... Good luck.

I have a 100 gal. tank and it worked great,It took a couple of days but my tank never had issues again and it kept working for over a year.

It will run for a while after using it, as it is in fact refilling the holding tank. It should stop after a while though. Depends on how much water you used, but it does seem to take a while to refill.

My 20 lb tank lasted about 8 hours, so looks like the smaller one would last a couple hours.

I am very sorry I don't know much about this, but so far it is very good. I have 15 gal. tank only. Thanks

Not to be insulting,but there is another way to tell it's on,your water will clear up. Depending on the size of the tank,(mine is in a 20gal.tall),it took 3 days to clear it up.

Depending on how high you turn the dial. Mine usually goes for 3 days or so on 1 tank.

Hi George,I would first check the pressure in the holding tank to make sure it is correct.Have seen where water will come out fast but trickle off quickly and this is sometimes the problem.

I started with 6 weeks long time period in my 60 gal tank, per bottle.Well, in 8 months time, my aquatic jungle has been harvested 3 times. My tank is 24 inches tall, and I had lillies growing ouy of the top. More plants....more CO2 I got another for a smaller tank and uses 6 times more due to a miniscule leak. :(. And they are expensive. I am a ruralite and am dragging my feet to get into town for a better setup. It may be a good "Starter" setup. BTW, the "leaker" valve on a 10 gallon moss shrimp tank, goes thru 6 times faster than my "jungle" 60 gal.....IMHO, the "20" is a piece of junk as well....Fluval needs to start over and do it right.......
