📐 Pool Sizing Guide

Sizing Principle: The filter’s flow rate should turn over the entire pool volume within 6-8 hours for optimal water clarity and hygiene.

Formula:

Required Flow Rate (m³/hr) = Pool Volume (m³) ÷ Turnover Time (hours)

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏊 Medium above-ground	30,000 – 50,000 L	Excellent – provides generous capacity
🏊 Large above-ground	50,000 – 70,000 L	Very Good – optimal turnover rates
🏠 Small in-ground	Up to 60,000 L	Excellent – ideal match
🏠 Medium in-ground	60,000 – 85,000 L	Very Good – recommended range
🏠 Large in-ground	85,000 – 112,000 L	Good – suitable with 8-hour turnover

This Filter:

📍 Flow Rate: 14 m³/hr

📍 Recommended Pool Size: Up to 84,000 litres (6-hour turnover)

📍 Maximum Pool Size: Up to 112,000 litres (8-hour turnover)

🔄 Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	Procedure
Check pressure gauge	Weekly	Note baseline pressure when filter is clean
Backwash filter	When pressure rises 0.5-0.7 bar above baseline	Run until sight glass shows clear water
Rinse after backwash	After every backwash	Run for 30-60 seconds to settle media
Inspect O-rings and seals	Seasonally	Replace if cracked, worn or flattened
Check media level	Annually	Top up sand if level has dropped
Full media replacement	Every 5-7 years (sand)	Replace entire sand charge

Pressure Gauge Guide:

📊 Clean filter baseline: 0.5 – 0.8 bar (note your specific reading)

📊 Backwash required: When pressure rises 0.5 – 0.7 bar above baseline

📊 Maximum safe operating pressure: 2.5 bar

⚠️ If pressure exceeds 2.5 bar, stop the pump immediately and investigate the cause.

Winterisation (UK Climate):

• Drain the filter tank completely via the drain port
• Remove and safely store the drain plug to prevent water accumulation
• Set multiport valve to “Winterise” position if available, or between settings
• Cover the filter or relocate to a frost-free location if possible
• Never leave water in the filter during freezing conditions as ice expansion can crack the tank

🪨 Filter Media Information

Compatible Media Types:

Media Type	Filtration Rating	Lifespan	Benefits
Silica Sand (Grade 16/30)	20-40 microns	5-7 years	Economical, proven performance, widely available
Glass Media	5-15 microns	10+ years	Finer filtration, requires less backwashing, eco-friendly
ZeoSand (Zeolite)	3-5 microns	5 years	Superior water clarity, removes ammonia and chloramines

Media Capacity: 140 kg

Recommended Sand Grade: 16/30 (0.5-1.0mm particle size)

Signs Your Media Needs Replacing:

• Persistent cloudy water despite correct chemical balance
• Short filter cycles between backwashes
• Sand or media particles returning to pool through jets
• Channelling visible through inspection lid
• Media more than 7 years old (sand) or 10+ years (glass)

🔬 Filtration Performance

Metric	Value
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass Media)	5-15 microns
Filter Area	0.28 m²
Flow Rate	14 m³/hr

Micron Rating Guide:

Rating	What It Captures
40+ microns	Visible debris, leaves, large particles
20-40 microns	Sand, dirt, visible sediment, hair
10-20 microns	Fine particles, some algae spores, pollen
5-10 microns	Very fine particles, most algae, bacteria clumps
Below 5 microns	Microscopic particles, requires glass media

💡 Tip: Upgrading to glass media can improve filtration from 20-40 microns to 5-15 microns without changing your filter.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The FVS24 is suitable for pools up to approximately 100,000 litres with a recommended 6-8 hour turnover time. With its 14m³/hr flow rate, it comfortably handles most medium to large residential pools.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads 0.5-0.7 bar above your clean filter baseline—typically every 1-2 weeks during swimming season, depending on pool usage and debris load.

Q: What filter media should I use?

A: The FVS24 is compatible with silica sand (Grade 16/30), glass media, or ZeoSand. The filter requires 140 kg of media. Glass media offers finer filtration and longer lifespan, whilst sand provides proven, economical performance.

Q: How long does filter media last?

A: Silica sand typically lasts 5-7 years with proper maintenance. Glass media can last 10+ years. ZeoSand should be replaced every 5 years.

Q: What pump do I need?

A: Match with a pump delivering 10-14 m³/hr flow rate. Do not exceed the filter’s maximum flow rate. Certikin Aquaspeed pumps are designed to pair optimally with Vision filters.

Q: What warranty is included?

A: The FVS24 comes with Certikin’s 10-year full tank warranty for residential installations, demonstrating confidence in the bobbin-wound fibreglass construction.

Q: Can I use glass media instead of sand?

A: Yes. Glass media is fully compatible and offers improved filtration (5-15 microns versus 20-40 microns for sand), requires less backwashing, and has a longer lifespan. Use the same 140 kg quantity.

Q: Is this filter suitable for saltwater pools?

A: Yes. The fibreglass construction and quality components are suitable for use with salt chlorinator systems.

Q: Why is my filter pressure higher than normal?

A: High pressure indicates the filter media is collecting debris and needs backwashing. If pressure remains high after backwashing, check for blockages or consider media replacement if the media is old.

Q: Can I install this filter myself?

A: Yes, experienced DIY enthusiasts can install the FVS24. However, we recommend professional installation to ensure correct plumbing, pump matching, and electrical connections for optimal performance and warranty compliance.
