Your message is in the right inbox. Replies go out within one business day — sizing questions usually land same-day. Check spam if nothing arrives; we write back plainly, which filters sometimes mistake for suspicious behavior.
Three answers in advance
The questions that arrive most, answered so your actual question gets a faster reply.
Do you sell fish or coral?+
No — Maren Marine is equipment only. Lighting, flow, pumps, filtration, dosing, controllers, and the rest. We'll happily help you spec the system your livestock will live in, but the livestock itself comes from your local fish store or a dedicated coral vendor.
Can you help me size a system before I buy?+
That's our favorite kind of email. Send your tank volume and dimensions, what you plan to keep, and how long it's been running, and we'll come back with a gear list that fits — not the biggest one we can sell you. It's free, and there's no obligation to buy from us.
Do you ship internationally?+
US only for now. Voltage and plug standards differ by region, and we'd rather not sell you a pump that won't run safely where you live.
