Hey all, Im thinking more and more ill need bite the bullet and take an aggresive stance against this issue. Ill post pictures later to make sure im actually dealing with byropsis and not something else. My water values have been where they should be but it doesnt seem to make the smallest dent on this stuff.... So my plan is to raise mg to about 1700? Its at a constant 1400 at the moment. My concerns are my snails, if i place them in a 5 l. Tank the time i treat do you folks think they will be alright? I also have an urchin, one of those that "burrow" into rocks (going to be hard to get my hands on him) as well as a small hermit. So my questions are these; A) how long does this kind of treatment take? B) should i risk leaving my inverts in? C) if instead of the mag therapy i used "dino x" or whatever its called my macro should be safe in the 5 l tank right? ( instead of the inverts) D) do i have any other option? Thank you!
