I made a big mistake and choose white sand for cap layer. and as u can see its getting dirty and so visible :(

any tips? since i shouldn't do water changes so often.

sorry for bad English

my Echinodorus' leaves turning yellow. it had some yellow leaves when i set up the tank ( 8 days ago) but now it's just keep getting worse. what should i do? i am using 1 inch of 70% top soil + 30% peat moss and caped it with 2 inches of sands.
