Using Vibrant for 8 weeks now and bubble algae is almost gone but phosphate has gone up to .10, it was between .04-.06. My chaeto has not died but do you think it has slowed down because of Vibrant use? The N03 has also risen from 15 to 25. Im thinking bubble algae was taking up N03/P04 but now dead nutrients are rising. Plus cheato is slowing down do to Vibrant use. Does this sound reasonable? Im also getting cyno on some of my sand bed now. Thoughts anyone. Thanks for any input to what actions I should do next. I hope this all makes sense.
