Anyone tried and/or knows what happens when you add a CO² source for the plants to a brackish tank?

Using CO² in brackish tank

I am curious to know about this too. I was thinkgin of toying with it myself but if anyone else has already done it I would like to know what kind of results were had.
i think it would be the same as in freshwater... any fish you have in a tank will make CO2, among other things. so i imagine that its just like having a heavily stocked tank without the amonia/nitrite/nitrate. so the plants grow, without water quality issues.
or you could try just heavily stocking your tank, but keep up on water changes... what is your SG by the way?
if you do try the CO2, do you have the gear to do it. ive been told a great way to make a CO2 system on a budget...
1- get a 2-3 ltr plastic bottle.
2- drill a hole in the lid and insert air tubing into it. the lenth of the tubing will vary depending on your tank hight. as long as he other end is in the water i think its ok. but the deeper it is, the longer the CO2 has contact time with the water, and the more effective it will be.
3- glue the tubing into the lid so its air tight, and throw an air stone on the other end in the tank
4- get some dried yeast from the baking section of the supermarket and place it in the bottle with some warm water to get it started.
as the yeast grows it makes CO2 like in a baking loaf of bread. depending on the yeast/water mix it can last up to 2 weeks im told.

Thanks for that, I'll give it try on a low dose first.
The SG of my tank varies between 1.003-1.006, I swap hi/lo SG at water changes to reflect the slight change one would find in the wild.
The tank is under stocked at the moment (2x F8s 6x BBGs), but I might add a pair of Orange Chromides or Celebes Rainbowfish.
CO² kit isn't a problem...

I've tried the 2-liter bottle thing several times over the past three years, it tends to run out of gas after 48 hours. Some say you can recharge it by emptying it out except for a little at the bottom, then filling it back up with water and sugar, but it's hit and miss.
I just keep my tanks heavily aerated, and there's enough ambient CO2 for good plant growth.
My roommates play paintball, I don't know what's wrong with me that I can't just buy a cartridge off of them and hook it up with a teeny ball valve to the tank...

how big is the tank? puffers are a really messy fish. they produce loads of waste products.
if you have the kit i say give it a shot. if it starts to effect the tank in a negative fashion you can always just take it out... so its worth a go...
Righty-ho... I'll fire it up and let you all know how well or bad it goes.

PS. Man this going to be one tricked out AquaOne tank... FBF, Skimmer, CO²...

I'm using CO2 injection in a FW tank for plants in a 75g tank. Its an 18kg bottle, been running the tank for over 2 years with ample gas remaining. I'm planning to setup a 150g rift cichlid tank with plants, but have been thinking about the effect CO2 has on my water params, particularly PH.
In my FW tank the PH drops to around 6.5 with CO2 (from the tap its neutral 7.0), which concerns me as I want to keep the PH above 7.5 for rift cichlids. Guess I'm gonna have to ensure the tank has adequate PH buffering
Don't care for the yeast reactor CO2 as they can pollute the tank water if incorrectly managed. If you're keen to get high-growth then a gas-bottle based CO2 system is a good investment. If you're only interested in just getting plants to grow then focus on their environment first - lighting, fertilisers, plus fish that don't eat / damage the plants .
