FIRST .... i have a SIX gallon heavily planted tank. ...

can i set it for 1 bpTWOseconds?

if i buy a paintball tank (from some unknown source) where do i get it filled (some other unknown source?) . I'm in central western NJ

up aqua has a inexpensive regulator as is http://www.plantedtank.net/forums/showthread.php?t=200869&highlight=

thoughts?

what if i go disposable?

i am trying diy but it's WAY to much for my 6 gallon i can't get it below 2 bps. so i have to keep taking it out.

With the right needle valve, yes, you can easily achieve 1 bubble per two seconds.

Do note that your bubble rate does not correlate with the amount of CO2 that is actually dissolved into the water column.

I would check out paintball stores for the purchase of cylinders/refills. Alternatively, some fire extinguisher places or home beer making stores will also refill cylinders.

You could also consider getting a larger (5, 10 or 20 pound) CO2 cylinder as well.

I would just go with a normal CGA320 regulator; that way, if you decide to upgrade to a normal (5 pound or up) CO2 cylinder, then you do not need to purchase a new regulator, etc.

Regulators with a CGA320 nipple can be easily adapted to paintball cylinders.

This is an expensive alternative. The cartridges tend to run out quickly.

remember we are talking about a SIX gallon tank... so think SMALL!

a 5 lb tank is bigger then my tank :icon_eek:

all i know is at 1 bps i'm gassing my shrimp... so i know it needs to be WAY slower then that... thus the disposable, as i'm not using much

I ran a 10 pound cylinder on an ADA Mini-S (3.5 gallons).

thanks!

okay JUST put in a drop checker (well 2 in different tanks)

one is a glass one, added dkh4 and 4 drops ph JUST put in tank it is blue
one is upaqua, added dkh4 and upaqua drops JUST put in other tank it's green

um... why is one blue and one green.. is it normal for them to start a certain color

how long for them to 'register'

I am not sure what is in the Up Aqua drops (whether it is just a bromothymol blue solution or if it is a mix of 4 dkH solution and bromothymol blue)...

I would trust the 4 dkH reference water and the bromothymol blue (your fist one) more than the second unless you know the composition of the Up Aqua drops.

When you add bromothymol blue to a 4 dkH reference solution, it should be blue.

It will take anywhere from 1 - 3 hours for the drop checker to register the CO2 levels inside the aquarium after it has been placed.

re did the up-aqua one ...

so it takes 1-3 hours for the co2 to register -- so theoretically i could gas my shrimp...

the one in the tank turned green.. bright healthy green... turned off the lights and droped a airstone in there... is that right? as the co2 is still going or can i /should i disconnect the co2 at the drop counter?

co2 going into the house is fine - right? a splitter where i can close the tank and open to air would be great .. hmm...

Yes, but just slowly increase your CO2 on a daily basis and watch your shrimp for any signs of stress.

Why would you turn off the lights and drop in an airstone? When the drop checker is green, your CO2 are at optimal levels (about 30 ppm, if you are using a 4 dkH reference solution).

I am also not sure what you when you say that you want to disconnect the CO2 at the "drop counter". Are you talking about the drop checker? Or perhaps the bubble counter? In any case, why do you want to disconnect the CO2?

co2 going into the house is fine - right? a splitter where i can close the tank and open to air would be great .. hmm...
Depends on the flow rate; a major leak of CO2 would not be good. A micro leak would not make a big difference. But again, why would you want to do this...?

You can also consider controlling your CO2 via a solenoid (this will allow you to control the CO2 on a timer).

um remember this is a DIY... so i don't have control... it just bubbles away and at 1200 feet above sea level it bubbles A LOT!

I would try using less yeast next time, then. This will slow down the amount of CO2 produced.

Alternatively, you can try using a less efficient method of CO2 diffusion.
