newbie question: Why doesn't the CO2 given off my the fish provide enough for the plants?

 

[black udder]

I believe the problem is when there are more plants than the CO2 provided by the fish can handle.

other parts..
CO2 tank.. buy or lease localy.. welding shop.. yellow pages can help here..
CO2 regulator to thread the parts in.. home brewery or whatever is cheapest.. the needle valve modification will make a standard one work.. they are about $40 on e-bay..

Total cost $60 + tank..

I was looking around on tropica's site and came across This

It shows the relation between Co2 and light, and their effect on plants in the aquarium. Some great information with some great understanding on why plants do the things that they do.

it was recently asked:

Is the carbo-plus CO2 system any good?

In short, no.

Here's some more detailed info.

Low Cost High Quality Regulator:

Low Cost High Quality Needle Valves:
http://www.stcvalve.com/DIMENSION-FV.htm Which sell for $7.37 for an in-line needle valve.

http://www.stcvalve.com/DIMENSION-CV.htm which is $6.17 for a needle vavle with an NPT fitting. This will screw directly into the solenoid.

The second link has a chart, showing the flow rate versus number of turns. Look at the smooth/flat flow curve on the 1/8 npt valve. I have one of these on my main tank and it really gives me some fine control.
