Troubleshooting Cloudy Water in Your biOrb Aquarium

Troubleshooting Cloudy Water in Your biOrb Aquarium

Cloudy water is one of the most common issues faced by both beginner and experienced fishkeepers—especially in compact systems like the biOrb aquarium. While biOrb tanks are designed for ease of use, water clarity problems can still arise due to feeding habits, filtration issues, or biological imbalances.

This guide will walk you through the most common causes of cloudy water in biOrb aquariums, how to fix them, and how to prevent them from returning—keeping your tank clean, healthy, and crystal clear.

 

Types of Cloudy Water and What They Mean

Understanding the type of cloudiness you’re dealing with can help pinpoint the cause quickly.

1. Milky White or Hazy Water

Usually caused by:

  • New tank syndrome (bacterial bloom during cycling)

  • Disturbed substrate or ceramic media

  • Overfeeding or uneaten food breaking down

 

2. Green Water

This indicates:

  • Algae bloom caused by excessive light or nutrient imbalance

3. Brown or Yellowish Tint

Often due to:

  • Organic waste buildup

  • Dirty filter cartridge

  • Natural tannins from driftwood or certain décor

 

Common Causes of Cloudy biOrb Water

 

1. Infrequent Filter Changes

biOrb filter cartridges should be replaced every 4–6 weeks. A clogged or old filter can:

  • Reduce circulation

  • Release trapped waste

  • Create a nutrient-rich environment for bacteria or algae

 

2. Overfeeding

Leftover food is a major source of ammonia, bacteria, and cloudiness. Only feed what your fish can consume in 1–2 minutes.

 

3. Inadequate Water Changes

A lack of regular water changes leads to buildup of dissolved organics. Aim for 20–30% partial changes every 2–3 weeks.

 

4. Too Much Light

Leaving your lights on too long can trigger algae growth, especially in smaller tanks.

 

5. Disturbed Substrate

Ceramic media in the base can release fine particles when stirred. Always add water gently and avoid strong disturbance during cleaning.

How to Fix Cloudy Water in Your biOrb Aquarium

 

Step 1: Replace Your Filter Cartridge

  • Use a new biOrb Service Kit

  • Includes filter, water optimiser, and cleaning pad

  • Never rinse and reuse the old cartridge

 

Step 2: Perform a Partial Water Change

  • Remove 20–30% of the water using a siphon

  • Replace with dechlorinated, temperature-matched water

 

Step 3: Add Water Treatment

  • Use biOrb Water Optimiser to bind harmful substances and promote beneficial bacteria

  • Optionally use a bacteria booster to stabilize your ecosystem

 

Step 4: Reduce Lighting Duration

  • Limit light to 8–10 hours per day

  • Use a timer to maintain consistency

Step 5: Check Your Feeding Routine

  • Feed small amounts once daily

  • Remove any uneaten food after 2–3 minutes

 

Ongoing Prevention Tips

  • Replace filter regularly (every 4–6 weeks)

  • Test water quality monthly using test strips or kits

  • Avoid overstocking your tank

  • Rinse decorations monthly in tank-safe water

  • Avoid over-cleaning—preserve beneficial bacteria on ceramic media

🧼 Tip: Cloudy water right after a water change is normal and should clear within 24–48 hours.

 

When to Seek Help

If cloudiness persists for more than a week after addressing the above, test for:

  • Ammonia or nitrite spikes

  • Improper pH levels

  • Equipment malfunction (e.g. air pump failure)

Persistent issues could indicate overstocking, cycling problems, or a need to reset your tank’s biological balance.

 

Conclusion

Cloudy water in a biOrb aquarium can be frustrating—but it’s also easily fixed with a systematic approach. Whether the issue is bacteria, algae, or old filter media, a few simple steps can restore your aquarium’s clarity in no time.
