Our affiliate programme rewards you for introducing APT to other aquarists, so commission is paid on referral sales - not on purchases you make for your own tank. Orders placed through your own affiliate link won't generate a commission payout.
This keeps the programme fair and sustainable for everyone. Commissions are funded on the basis that they bring new hobbyists to APT, so directing them to genuine referrals is what lets us keep the rate as generous as it is. It's not a discount mechanism on your own purchases - it's a thank-you for the ones you send our way.
The best (and easiest) way to earn is simply to keep sharing your link where fellow hobbyists will see it: your build threads, videos, group posts and recommendations. Every real sale it drives is yours.
