I have had on going problems with my frogspawn for the past week or so. I started a thread here then about my frogspawn releasing tips. It was stable until I scraped some coralling algae into the water column. Could this coralline dust melted my frogspawn heads? In a matter of 48 hours it went from a beautiful 9 head piece with 12 new growths on the bottom of it to 9 heads of brown sludge. Any one have any ideas?
