Blue Thumb Small DIY Pond Kit [PB1212]

Blue Thumb Small DIY Pond Kit

Serenity Series • Small DIY Pond System • PB1212

The Blue Thumb Small DIY Pond Kit combines the primary equipment for a water garden up to 8' × 11' × 2' deep: liner and underlayment, a skimmer, a biological waterfall filter, a 1,800 GPH pump, plumbing, installation supplies and a maintenance kit. It is an entry-level system for homeowners and installers who want compatible core components in one package.

The DIY Pond Skimmer 90, DIY Pond Waterfall 1200 and Clear Water 1800 pump create a coordinated circulation and filtration path without requiring you to size the principal wet components separately.

The skimmer collects floating debris and protects the pump. The waterfall box, filter mat and Bacti-Twist media support filtration before the water returns to the pond.

The fish-friendly EPDM liner can follow pond curves and planting shelves, while the waterfall adds movement and sound. You choose the separately sourced rockwork and planting plan that fit the site.

The 8' × 11' measurement is the maximum pond size, not the complete work-zone footprint. The skimmer extends beyond one pond edge and measures 16.25" D × 13.25" W × 14.75" H. The waterfall box sits at the opposite edge or at the head of a short stream and measures 19" × 15.5" × 14.5" H.

Pond contours, shelves, liner overlap, rockwork and the operating water level affect the finished water surface and volume. Review the Pond Planning Guide and lay out the pond, skimmer, waterfall and surrounding stone before excavation.

The primary pond equipment, plumbing and startup supplies are included. The linked component pages help you review individual specifications; where a linked page has options, use the exact model or size named below.

This is a built-in landscape project that requires excavation, level and compacted equipment locations, rockwork, plumbing and access to water and a protected electrical supply. Use this sequence for planning and follow the official guides for complete instructions.

Confirm the pond shape, shelves, finished water level and the extra space required for the skimmer, waterfall box and surrounding rockwork.

Position the waterfall opposite the skimmer. Prepare compacted locations, set the skimmer level and give the waterfall box the slight forward pitch stated in its guide.

Excavate the planned contours, remove sharp objects and install the protective underliner before placing the 45-mil rubber liner.

Attach the liner to the skimmer, position the waterfall box and connect the included 1.5" flexible PVC plumbing and check-valve hardware exactly as shown in the Serenity guide.

Install the pump, filter mat and Bacti-Twist media. Add the required separately sourced rocks and gravel without pulling the liner tight at the waterfall transition.

Fill the pond, start the circulation system and check flow, water level and every connection before completing the surrounding landscape.

Inspect the skimmer net and mat regularly; the Serenity guide notes that cleaning is often needed every 10–14 days, depending on debris and fish load.

Keep the operating water level approximately 3/4"–1" below the skimmer opening.

Clean waterfall media when needed; the guide recommends a thorough cleaning about once a year when water is coldest or below 50°F.

Use pond water for media rinsing when possible so chlorinated tap water does not harm beneficial bacteria.

Connect the pump to a GFCI-protected outlet in a dry location protected from flooding.

Keep the pump submerged while operating and never run it dry.

Disconnect power before handling, cleaning or troubleshooting the pump.

Never lift the pump or remove the plug by pulling on the power cord.

If prolonged freezing or ice could affect the pump or plumbing, remove the pump and store it where it cannot freeze. Review both the Serenity installation guide and the Clear Water pump manual before winterizing, and follow the seasonal pond-care guide for leaves, fish, plants, filtration and gas exchange.
