I have a number of sarrs that I've recently sprouted from seeds. As this is my first attempt, inexperience has resulted in an issue that I'd like input on.
Initially the two 6x12 trays were in a 55 gal tank. One tray has a basic sand/peat mix topped w/ chopped LFS, the other just the sand/ peat mix. I've run into an issue where the LFS is looking, well, nasty and a mold has started on the sand/peat tray. I've since removed the trays from the tank and have them open w/ one 4' 4-bulb light fixture about 10-12" up.
Can I combat this mold, and if so, how without adversely affecting the seedlings. Also, suggestions on how to minimize this the next time would also be greatly appreciated.
