no, trace elements are not necessary if you do frequent water changes, in which case new source water is added which will contain trace elements. trace elements are another of those chemical "quick fixes" that companies want to sell you as a replacement for regular tank maintenance. they go along with those liquids that claim to kill algae, clear up cloudy water, and remove ammonia or nitrite.race22 said:Is it important to get Fresh Trace? i have 20g freshwater aquarium
