What's the best to remove the combination of nitrates and ammonia in freshwater tank? Algae filter screen, planted refugium, zeolyte crystals or Denitrator? Any other good ones and which works the best?
Austin;3470120; said:a fully cycled tank will do a bad ass job of removing ammonia and water changes will work wonders on nitrates. it's insane.
Why would metals build up in a normal system without water changes? unless your constantly topping off the water level I guessNoto;3473535; said:Yes, once established the algal scrubber will remove all nitrogenous wastes. You won't have to do water changes nearly as frequently, though there are still some things in the water (pheremones, metals, etc.) that can build up without water changes and other things (various minerals and trace elements) that your plants or algae need that they can only get from water changes. So, you will be exchanging frequent water changes for infrequent water changes + weekly maintenance of scrubber.
