What you should know about algae in a pool
If you’re choosing between a fiberglass or gunite (concrete) pool in Maryland, understanding how each handles algae is key. At Ardent Outdoor Living, we specialize in fiberglass pool installations because they offer a cleaner, more manageable solution, especially in our humid, algae-prone climate.
The Algae Problem with Gunite Pools
Gunite pools are porous, which means algae can easily root into the surface. Even with regular brushing and chemicals, algae can persist, leading to:
-
Discoloration:
- Algae in pools can often be black or mustard in color
-
Higher chlorine costs
-
Time-consuming maintenance:
- Due to the concrete, places for algae to seep into the cracks of the pool and begin to grow are a problem that requires lots of maintenance
This is especially true in Maryland and Virginia, where warm summers and fluctuating humidity create ideal conditions for algae growth.
How Fiberglass Pools Solve the Problem

Fiberglass pools are engineered with a smooth, gel-coated surface that resists algae attachment. Here’s why Maryland families are making the switch:
-
Algae-Resistant Finish: No tiny pores for algae to take hold (this is unavoidable in gunite)
-
Lower Chemical Usage: Requires less chlorine to stay clean
- Easier Cleaning: No need for acid washes or frequent scrubbing
Built-In Circulation Enhancements
Top fiberglass brands like Aqua Technics and Okeanos include smart features like built-in ledges and benches with integrated water flow—reducing dead zones where algae can grow.
A Smart Investment for Maryland Homeowners
Fiberglass pools are faster to install, cost less to maintain, and avoid long-term resurfacing costs that are common with gunite. From Silver Spring to Annapolis, homeowners appreciate the time and money they save year after year.
