wilkyb Posted April 10, 2021 Share Posted April 10, 2021 (edited) Any ideas what is happening / what can be done? It’s 75/25 sand-garden soil substrate, seeds sprouted after about 10 days, then I topped it with 1/4” sand. 20gal tank with a sub pump filter but no air injection. It’s been running for about 3 weeks now & it begins to melt; 4 days ago I had furry see-through and very thin cotton-like stuff gathering on the grass, and now they are going brown from the tips & dying.
