Linda4fish Posted January 28, 2022 Share Posted January 28, 2022 It seems every time I add as little as two root tabs to my 29 gallon planted tank my plants benefit …..and algae starts to grow and nitrates go up requiring water changes…. Thus decreasing nutrients idk what to do! Link to comment Share on other sites More sharing options...
colo3000 Posted January 28, 2022 Share Posted January 28, 2022 How high are your nitrates? How deep is your substrate and how deep are you inserting the root tabs? What kind of substrate do you have? If your substrate is coarse and/or shallow, the root tabs will be more exposed to the water column and leach more fertilizer (nitrates) into the water column. 1 Link to comment Share on other sites More sharing options...
Mmiller2001 Posted January 28, 2022 Share Posted January 28, 2022 Stop using them and dose the water column appropriately. Link to comment Share on other sites More sharing options...
