Mistake: The Reef Tank Killer You’re Probably Building With ⚠️
If you are planning a custom reef tank build or buying a manufactured stand, do NOT make this mistake.
Marine plywood on the outside looks great, but using standard MDF (Medium-Density Fibreboard) for your cabinet interior is a ticking time bomb. 💣
In a saltwater system, humidity, salt creep, and minor splashes are inevitable. The moment that saltwater hits standard MDF, it acts like a sponge. Within 8 months, my original cabinet was already swelling, splitting, and delaminating—compromising the structural integrity holding up hundreds of kilos of water.
If you’re building or buying, ensure your stand is constructed from fully waterproof materials like solid PVC, powder-coated aluminum, or high-grade marine plywood treated with a heavy-duty water-resistant sealant.
