Discussion Title: Biocube upgrades
We’re answering your aquarium questions right inside the Big Fish Forum, and this post comes from one of the threads that kicked things off: a request for a clear Biocube 30 upgrade breakdown. When reef keepers ask for help, we give straightforward, step-by-step guidance — no fluff, no confusion. This guide reflects exactly how we respond in the forum, and we’d love to hear from you too. If you’ve got your own Biocube tips, tricks, or upgrade recommendations, drop them in the comments below — and feel free to ask your own questions in the forum anytime.
