What is going on with my plants? I dose 2 times a week with Flourish Comprehensive and have Seachem root tabs under all three swords. I have had 4 fish die and I dont know what is up. Amm. 0 Nitrite 0 Nitrate 10. PH 8.0 Tank has been going for over a month now. I am getting Diatoms and I think that is normal for a tank less then 3 months old. I dont know what the problem is. I am running a wet-dry filter about 20 gallons. I am doing my 50% water change every week and also about a 10% everyday day because of my fish dying. I am using Prime every water change. Now all my plants are starting to die. Tank is about 1 1/2 month old... Can some body figure it out? Tank was cycled by pure Ammonia and fishless. Tank used to be a salt water tank but I cleaned it out very well. It is drilled...
