When people start planning a custom aquarium, one of the first questions they ask us is:
“Should I choose Starphire or regular float glass?”
If you’ve heard the terms “low-iron,” “ultra-clear,” or “Starphire,” but aren’t sure if you actually need it, this guide will help you make the right choice.
Below, we break down the real differences, clarity levels, cost, and when float glass is the smarter option.
What Is Float Glass?
Float glass is the standard glass used in most aquariums. It offers:
- Clean viewing (as you go thicker it has a green tint)
- Strong durability
- Reliable scratch resistance
- Excellent value
- Works well for both freshwater and saltwater systems
Float glass is the industry standard for custom tanks for a reason:
It’s strong, clear, affordable, and perfect for most setups.
What Is Starphire (Low-Iron) Glass?
Starphire is a type of ultra-clear, low-iron glass designed to reduce the green tint found in thicker float glass.
People choose Starphire when they want:
- Maximum clarity
- Brighter whites and blues
- True coral coloration for reef tanks
- Premium aesthetics for showpiece aquariums
It does look incredible but it comes at a slightly higher cost.
Side-by-Side Comparison
Feature | Float Glass | Starphire (Low-Iron) Glass |
|---|---|---|
Clarity | clear | Ultra-clear, minimal tint |
Strength | Strong + durable | Strong, but slightly softer |
Scratch Resistance | Higher | Slightly softer surface |
Price | Most affordable | approx. 15-30% higher cost |
Best For | Freshwater, planted tanks, nanos, most reefs | High-end show tanks, coral displays |
Is Starphire Worth It?
Sometimes but not always.
You benefit from Starphire if:
- Your tank is thick glass (75g+)
- You want a premium luxury display
- You run an SPS-dominant reef where color accuracy matters
- You’re placing the tank in a bright, open living space
You don’t need Starphire if:
- You’re building a nano or mid-size tank (under 75g)
- You want the best value
Which Glass Should You Choose?
Here’s the simple answer:
>If your tank is under 75 gallons float glass is almost always the smarter choice.
>If you want a large, display tank Starphire may be worth it.
What do we use?
For our custom aquariums, we primarily use premium Belgian low-iron glass a superior alternative to standard float glass and comparable to Starphire® in clarity.

Starphire® is a branded low-iron glass while Belgian low-iron glass is the same material category, sourced from European manufacturers rather than North American branding.
