fluval pressurized co2 systems.???

Has anybody tried one of these? The bigger kit for up to 40 gal is on back order everywhere.

Would the smaller 20 gram kit be enough? I am willing to bet the regulator would fit the larger 88 gram cylinder if it’s just a problem with volume. Both kits come with a regulator but the 20 gram has a intake bubble counter ladder diffuser as one. The 88 has a small diffuser and external bubble counter.

Even with the above I get beard algae I have otto cats and Siamese algae eaters and they are not enough to keep it at bay. I have fazed back my lights to 8 hours a day and I still have it.


The tank is a 20 gallon long with low tech plants (crypt, java moss, java ferns, anubus and Amazon swords) and just enough light. I dose with flourish, iron and excel but doing the excel each day is a pain. Substrate is flora grow. I had good plant luck with the diy organic co2 but the PH fluctuations were less then positive for my fish keeping skills. It did keep my algae in check and seemed to encourage plant growth.

Hey man, I use the small 20g kit from fluval (for 30 bucks i couldn't resist) for my 10g long, and it works fine for me! The only thing is, it's a pain in the ass to check up on your tank twice a day and turn the nob (i'm a complete lazyass). Since you're doing a low-tech setup C02 isnt entirely necessary, but will definitely promote growth. I run a semi-high tech setup:
-Riccia Carpet
-Baby Tears
-Bacopa Australis (low)
-some other plant that looks like big glossostigma.

They are flourishing... a bit too much I think. The Bacopa Australis grew so much that it blocked out all the light at the bottom and reached the top of the tank. I had to cut it cuz the light wasnt reaching and the stems were rotting. I have absolutely no algae problems, and i dose with Flourish Excel every day. (and this is only with one 15w bulb nutrigrow light from coralife)

Soooo that's my story. have fun if you decide to get it!

OH! and if you do decide to get it, http://www.amazon.com/16-Gram-Threa...US7C/ref=sr_1_1?ie=UTF8&qid=1297833174&sr=8-1 is a good refill from what i've heard. 16 for 13 bucks is cheap! I don't give my plants a full dosage so i've been running on the first canister it came with for a month now. cheers!
