just want to know if you guys clean your substrate before you put in your tank? i got flourite substrate by seachem and it was recommended per instruction not necessary to pre clean them before put the tank. just add water slowly. that what i did and when i plant the plants or move thing around it get murky.. I'm so tempted to pull it all out and wash it. and it gonna be suck to pull out my DHC because i just planted week ago. but hate the fact it dirty.
