i think i need to get some co2 into my 300 liter tank, my plants keep dying. ive tried different fetilizers that only slows the decay.

id prefer to use cartridges as i can just order more online rather than get a tank refilled but the ones ive seen say up to 150l tanks. ive never used co2 before so buying an all in one setup would be better for me to start with.

so my question is are cartridges not enough for a bigger tank?

Haven't tried cartridges but my guess would be that you will run out very quickly with 300 liters of water. Not even sure I would use it on 150 liters.

I've tried the 88g disposable cartridge. It lasted about 2 weeks on a 75 gallon (300 liter) tank.
One 88 gram cartridge costs more than CO2 refill on 24 oz (680 grams) paintball cylinder. Sure, you need a paintball cylinder (around $50 where I live) but the CO2 lasts 2-3 months.
If you buy the kit, you might want to keep the regulator and the diffuser for later use (on a paintball cylinder). The bubble counter that comes with a kit it's usually garbage and the cartridges- a rip-off.
