Plants need co2 for good growth.
Fishcove Aquatics offer a co2 refill service, Firstly drop us a message so we can confirm the size of the bottle.
Fishcove Aquatics will then let you know on a price and when to bring the bottle in. Normally Monday to Friday there is a 24 hour turn around but some can take 48 hours. You will always get your bottle back and it’s not replaced for an out of date bottle that could be dangerous.
