Anacharis vs algae


Will a low light tank with long hours ....

Can Anacharis prevent algae outgrowth, since it is a weed and will absorb nutrients?

Default Anacharis vs algae

Try a floating plant such as dwarf water lettuce, they absorb nutrients like crazy!!

Hello Cur...

Brazilian water weed (Anacharis) is a good floater and uses dissolved nutrients in the tank water much more effeciently than a single-celled plant like algae. Long hours of low to moderate light aren't the main cause of algae growth, it's high phosphates in the water from feeding too much.

Fish need very little food. They're small and have a stomach the size of one of their eyes. You really need to feed much less and feed better quality food. I feed a variety of frozen just a couple of times a week and sometimes a bit of freeze dried food. The fish spend the rest of the time looking for leftovers and keep the tank cleaner. There's no extra food to dissolve in the tank water and feed the algae.

Just one reporter's opinion, though.

Not all algae are single-celled and they're also not all plants, as some are part of the Kingdom Protista. Some, like Blue Green Algae, aren't even algae but cyanobacteria.

It's also not overfeeding that's likely causing an algae issue. Head over to our Algae section for a really helpful sticky post and for basic information on how to combat algae.

An imbalance between lighting, CO2 and nutrients is the root of your algae issue. If you've got a photoperiod that's too long, that's likely your culprit. Using floating plants will cut your lighting levels down and will come in handy.

What are the dimensions of your tank and what specific lighting do you have? How long will your photoperiod be?

I agree with this.

The idea of excess nutrients causing algae is an old school myth IMO. It's not excess phosphates or nitrates that cause algae. I think this stems from the idea when we over feed we see high phosphates and nitrates so they must be the culprit, they're not. The organic foods we feed decay producing ammonia. Ammonia is the cause in regards to excess "nutrients" being blamed for algae, not phosphate and/or nitrate. People have been dosing nutrients in excess for years without issue. Those nutrients do not include ammonia. Adding plants that out compete algae for the ammonia(um) as nutrients quickly will help with algae issues.
