Thanks Guys. I will try get rid of the snails. Will keep you posted.

I have Java Fern planted in my 30 gallon tank.
See the photos, the leaf looks to have holes as if something is eating them.
I have 3 rose barb and some snails.

Is this normal and expected ? or something going wrong with my fertilization / CO2 / Light....etc..

One of the topics http://www.gwapa.org/forum/viewtopic.php?f=34&t=5172 I see lot of people buying Glutaraldehyde.
So my question is, Once I buy a pressurized CO2 system then, is it recommended to suppliment with Glutaraldehyde or flourish ?

The below dual stage is this a better one compared to Milwaukee?

or any other recommendations?

Can you recommend me some good regulators?

For the 1st time, I am setting up CO2 for my 30G tank. I am getting rid of DYI CO2 and planning to buy the below. 1. 5 LB CO2 Cylinder, Aluminum -- $55.87 2. Milwaukee Instruments Solenoid Valve, CO2 Regulator with Bubble Counter -- $89.99 3. Air Line Jumper 5' w/screw clamps - KegWorks -- $5.49 4. ...

Thanks guys. I will plan for the saturday meeting.

Reading different blogs and article, now I have decided to do some shopping. I already have 1. "Eco - complete substrate" 2. T5 HO ( 650 nm X 6000k ) (2 * 24 W) 3. Flourish Excel (As carbon source) + DIY CO2 4. Flourish Tab (as root fertilizers) For the Fertilizers -> what exactly to buy ?...
