my tank is going into its 4th week, and i think i made a mistake of adding TMG at the second week... my tank is a 50 gallon with 4 wpg, i recently did a filter change on the canister filter and then the tank became cloudy, the hygro sunsets are doing good, but the rest seems dying. The stargrass are burning out and the leafs are falling, and the others are just not growing! the Ph now is around 6.8... should i just wait for the balance to settle down and not do anything for now? wa should i do right now while i'm waiting for my test kits to arrive? please help
