Same thing happened when I added my Aragamax. Others have suggested tricks like putting plastic bags over the sand and then pour the water in, but eventually the sand will kick up when you move things around when you add the LR
The walls were extremely dusty for me and the water was even worse! Like others have said, the water will clear up when the bacteria starts to spread. I got impatient and used an old aqua clear hob
filter with just the carbon and the water cleared up quickly. I don't know if this was harmful or not , but it worked great. Any ideas on this, guys and gals?
