Common questions about launching aquarium co2 canister refills subscriptions on Shopify with Beez.
We typically offer 12oz, 24oz, and 60oz CO2 canisters to cater to various aquarium sizes and plant densities. Check our product page for current availability.
The ideal frequency depends on your tank size, plant density, and CO2 injection rate. Most customers choose monthly or bi-monthly, but you can adjust your frequency anytime in your customer portal.
Absolutely! You can easily pause or skip an upcoming delivery directly from your customer portal. Just make sure to do so before your next billing date.
We ensure all canisters are thoroughly inspected before shipping. If you receive a damaged or faulty canister, please contact our support team within 7 days for a free replacement.
While our subscription focuses on refills, we do offer starter CO2 systems as a one-time purchase, suitable for various tank sizes. These can be bundled with your first refill.
