How can I remove red algae and a sulphur odor from water?


Answer by  sleepyjey (248)

Have you tried chlorination? It removes most odors including sulfur and iron odors from water. Don't overdo it as chlorine itself has a smell that may not be pleasant if it's too much. Use 2. 0 mg / liter chlorine for every 1. 0 mg / liter hydrogen sulfide

Some out of the box ideas for the algae - use hermit crabs if possible, adjust the lighting, use a salt-sea mix. Check the nitrate levels in your tank too.

Activated carbon removes most tastes and odors from water and is easy to use. Works only for trace quantities. Depending on how bad the sulfur smell is you can use chlorination, aeration, a Manganese Greensand Filter or even an iron filter.

Regularly rinse and clean the tank including the filtering system. use an adequate light source. I must add that however careful you care algae will grow and regrow and it can be frustrating!

For the algae my only advice would be to never use chemicals - these inhibit the useful bacteria and plants in an aquarium and in the long run cause more harm than good!  add a comment

A 25% water change every 2-3 weeks helps in clearing up algae and their nutrients. Ensure that there is constant flow of water as this prevents the spores from settling and starting their germination/growth.  add a comment

Go to an outdoor type store, that sells pond equipment. They will be able to test your water and give you chemicals to fix the situation.

Sulphur odors in water can be caused by algae or bacteria. If you already know that you have a red algae problem as well, it can be easy to treat in one shot. To remove the algae, you should first skim out as much of the algae as possible then adjust your nutrient levels to prevent it from returning.

You should cut back on feeding the fish, clean the filter, and change the water frequently, at least twice per week. Hermit crabs or live rock can reduce the amount of red algae.

Purchasing and installing a water softener may help your problems. Get one that is designed to filter the water and remove unwanted impurities. If your water is colored your problem may be in the pipes leading into your home, in this case a professional would be needed to clean out your plumbing system.

This usually results in a pool of water. I recommend using bleach as it will remove the algae and bad sulphur smell.
