Apulo Posted April 11, 2022 Share Posted April 11, 2022 My goal since setting up my two tanks is to do virtually zero water changes. I have live plants in both and dose liquid ferts three times a week and root tabs once a week. If Ii show an acceptable (20-40ppm) nitrate and everything else is good, do I need to do water changes?

lefty o Posted April 11, 2022 Share Posted April 11, 2022 if water conditions are good, and everything in the tank looks happy and healthy, no you dont have to do water changes. i let the tank dictate when and if it needs a water change. i dont subscribe to the every week water change ( good thing for beginners who havent got a handle on things yet, so there is a place for it). you really have to have a perfectly balanced tank to never do water changes, but a well balanced tank can go for very long times without.

Apulo Posted April 11, 2022 Author Share Posted April 11, 2022 I am testing every other day currently just to make sure nothing is going wrong and so far, things have been doing great. I'll probably reduce my testing to once or twice a week once I have confidence things are going to stay great lol. 1 Link to comment Share on other sites More sharing options...
modified lung Posted April 11, 2022 Share Posted April 11, 2022 Having a conductivity or TDS meter makes eliminating or reducing your water changes a lot easier. They let you monitor the buildup of non-specific ions that usually aren't tested for just by shoving a probe in your tank. Link to comment Share on other sites More sharing options...
