Active Aqua Pre-Drilled 55 Gallon Drum with Locking Lid

The pre-drilled holes are located on the locking lid, making it easy to install grommets and run tubing into your reservoir. This design allows for clean, professional-looking connections while maintaining a secure seal.

The pre-drilled holes are designed to accommodate standard hydroponic grommets and fittings. You can customize the ports for various ebb & flow grow systems or multi-bucket setups like the Active Aqua Root Spa 4 Bucket Deep Water Culture System.

Yes, the drum is constructed from food-grade HDPE, which is safe for storing water and hydroponic nutrient solutions. To maintain high dissolved oxygen levels, we recommend using an Active Aqua 20W Commercial Air Pump.

While the HDPE material is durable, prolonged exposure to sunlight can promote algae growth. If using outdoors, we recommend placing the drum in a shaded area or using an Active Aqua 1/2 HP Chiller to prevent nutrient solution overheating.

Clean the drum between growing cycles using a mild bleach solution (1 part bleach to 10 parts water) or hydrogen peroxide. Rinse thoroughly after cleaning. The smooth HDPE interior makes cleaning easy and prevents buildup of residue or biofilm.

The drum's 23-inch top diameter will fit through most standard doorways. However, measure your specific doorways and hallways before purchasing, especially if you need to navigate tight corners or narrow passages.

We do not recommend stacking drums when they are full, as the weight could damage the lower drum and create a safety hazard. When empty, drums can be nested together for storage to save space.

The locking lid creates a secure seal to prevent spills and contamination, but it is not completely airtight. This allows for proper gas exchange, which is important for maintaining healthy nutrient solutions. The pre-drilled holes will also affect the seal once fittings are installed.
