Is your septic system feeling sluggish? Are odors turning your backyard barbecues into solo events? It's time to introduce your septic tank to Fresh Flush Disks—the non-invasive, power-free solution that transforms your waste management from "eww" to "woo-hoo!" How To Install

Fresh Flush Disks for Conventional Systems or Holding Tanks.

TL;DR (Too Long; Didn’t Rinse)

ATUs = 2 Disks. Oxygen helps out. Find Them Here
Conventional Tanks = 4 Disks. Oxygen is lazy. Your tank needs backup.
Either way, your nose wins.

💩 Why You Need 4 Fresh Flush Disks in a Regular Septic Tank (and Not Just 2)

It’s not a scam. It’s science. And poop. Lots of poop.

Let’s Talk Dirty (Scientifically Speaking)

Your average Conventional Septic Tank or Holding Tank is like a lazy roommate: it just kind of sits there while all your waste piles up. No help. No motivation. No gym membership.

Meanwhile, Advanced Treatment Units (ATUs) are like that overachiever who’s doing burpees at 5 a.m. They come with blowers and aerators that pump oxygen into the tank. This oxygen is like a protein shake for good microbes — it powers them up to eat, digest, and break down all that… um… “material” more efficiently.

System Type	Oxygen Levels	Microbial Activity	How Hard Fresh Flush Has to Work	Disks Needed
ATU	High (thanks, aerators!)	Active, energized microbes	Just a little boost to balance the system	2 Disks
Conventional Tank	Low (no aeration)	Sluggish microbes in a funky soup	Fresh Flush must compensate for poor oxygen & high waste load	4 Disks

So Why 4 Disks in a Conventional Tank?

Because you're asking them to:

Deal with more waste (higher BOD/COD)
Work in a funkier, smellier, low-oxygen environment
Keep your tank in balance without help from fancy aerators

It’s not just about doing the job — it’s about doing it consistently over time. Four disks = full coverage, full flow, and full stink suppression.

In ATUs, oxygen is pumped in, so microbes can do their job. But in conventional tanks, it’s mostly anaerobic (low-oxygen) conditions. That means:

More smelly byproducts like methane and hydrogen sulfide
Slower breakdown of sludge
Greater buildup of solids and pathogens
Higher levels of BOD and COD — and more work for the microbes

This is where Fresh Flush shines: they don’t add oxygen, but they do improve the energetic environment so water and waste molecules:

Have higher entropy (freer molecular movement)
Allow nutrients and electrons to transfer more efficiently
Make it easier for microbes to digest waste even in low-oxygen conditions

Think of the disks like yoga instructors for your poop tank — helping stressed-out sludge find balance and flow. But in a conventional system? You need more instructors.

Why Your Septic System Will Thank You:

Nitrogen Reduction: Fresh Flush can decrease nitrogen levels in your septic tank by up to 60%, promoting a healthier environment and reducing the risk of groundwater contamination.
Accelerated Sludge Decomposition: Speed up sludge breakdown by a factor of 1.5, meaning fewer pump-outs and more efficient waste processing.
Odor and Greenhouse Gas Control: Say goodbye to unpleasant smells and hello to fresher air, as our disks help remediate greenhouse gas and ammonia emissions.
Pathogen Reduction: Reduce coliform and other pathogens, contributing to a safer and cleaner system.
Nutrient Concentration Reduction: Lower nutrient concentrations in wastewater runoff, leading to cleaner waterways and a healthier ecosystem.

Set It and Forget It:

With a service life exceeding 15 years, these disks require no electricity, chemicals, or consumables. Simply install them as directed, and let them work their magic.

Installation So Easy, Even Your Teenager Could Do It:

Installation is straightforward. Just ensure the disks are positioned horizontally—because even disks need to lie down on the job. Check out our installation page for more information.
