Merkia 7.5" Floating Chlorine Dispenser | Best Pool Floater

Quick summary

The Merkia 7.5" Large Floating Chlorine Dispenser is a simple, inexpensive way to keep your above-ground pool sanitized without constant fuss. Built to hold standard 1"–3" chlorine tablets, the Merkia floater offers an adjustable release, a stable wide base to resist tipping, and an easy top-loading cap — ideal for homeowners who want reliable, low-maintenance chlorination and a low-cost affiliate pick to recommend.

Why pool owners like it:

• Large 7.5" diameter gives good buoyancy and stability in wind or mild waves.

• Adjustable vent/flow control (multiple settings) to tune chlorine release.

• Top-loading design — pop open, drop tablets in, close — no tools.

• Fits common tablet sizes (1", 2", and 3") so it works with most pool chemicals.

• Light, durable plastic is rust-proof and easy to rinse/clean.

• Affordable and perfect for routine weekly chlorination of above-ground pools.

Key features (what to expect):

• Size: 7.5 inches diameter — large float for steadier operation.

• Tablet compatibility: Holds 1"–3" chlorine tablets (trichloro or dichloro).

• Flow control: Rotating vent or adjustable dial lets you set slow/medium/fast dissolution.

• Build: UV-resistant plastic with weighted or wide base to reduce tipping.

• Use case: Best for regular sanitizing of above-ground pools, spas, and small inground pools.

How to use (3 easy steps)

1. Open the top cap and load 1–3 chlorine tablets into the chamber (follow tablet manufacturer guidance).

2. Set the vent/dial to the desired flow (start at low/medium and monitor free chlorine).

3. Place the floater in the pool away from skimmer outflows; check and refill weekly and test water regularly.

Tip: Start with a conservative setting and test free chlorine (1.0–3.0 ppm free chlorine is typical for home pools) after 24 hours — then adjust.

Best practices & safety:

• Never mix different chlorine products (e.g., shock + tablets) in the floater — keep incompatible chemicals stored apart.

• Always use gloves/eye protection when handling concentrated chemicals.

• Keep the floater away from pool ladders or suction lines that could trap it.

• Remove the floater when adding shock or when children are in the pool for direct supervision.

• Test water 2–3× per week in warm weather; adjust floater setting accordingly.

Pros & cons:

Pros

• Inexpensive, low-maintenance continuous chlorination.

• Wide, stable base reduces tipping and slows tablet loss.

• Adjustable flow for better chemical control.

• Works with standard tablet sizes (1” – 3”) — easy to refill.

  
  

Cons

• Passive dosing — not precise like automatic feeders or inline chlorinators.

• Tablets can dissolve faster in high circulation areas; placement matters.

• Plastic parts can wear over many seasons — replace if cracked or warped.

Who is this best for?

The Merkia 7.5" floater is a great pick for budget-conscious above-ground pool owners who want a “set-and-forget” sanitizer between weekly maintenance sessions. It pairs well with a good test kit and a weekly shock schedule for reliable, safe water.
