smicko Posted October 28, 2015 Report Share Posted October 28, 2015 Howdy plant peeps, I'm using a bba treatment in my tank and I can't waterchange for at least two weeks which got me thinking. Are waterchanges really necessary in a planted tank? The main reasons for waterchanges is to remove nitrates and replace minerals that have been depleted, so if the plants consume nitrates and minerals are dosed would that negate the need for them? I don't think the water would go stagnant as there is flow and by injecting c02 the plants release oxygen back into the system, would that be a correct assumption? What are peoples thoughts on this subject? Cheers mick Link to comment Share on other sites More sharing options...
bluebelle Posted October 29, 2015 Report Share Posted October 29, 2015 Theoretically it should work. I did not do WC for as much as 4 weeks, but by than something was not right. The whole tank seemed somehow to go downhill. So now it's back to WC every fortnight. Link to comment Share on other sites More sharing options...

smicko Posted October 29, 2015 Author Report Share Posted October 29, 2015 Thanks [MENTION=960]col[/MENTION], that's a good read and it seems different strokes for different folks. It might be because I'm so used to waterchanges but it feels wrong to leave the tank for 2-3 weeks without one. Cheers mick Link to comment Share on other sites More sharing options...
