Can you do this? I've always added the substrate before the fish but right now I have bare bottom on my 225 and would like to put some sand in it soon. I used to wash all my sand outside but the outside water is completely frozen so I can only really do it indoors and it's kind of time consuming.
Has anyone just put the sand in and let the filters clear the water? is this dangerous whilst fish are in the tank? I assume it probably would be quite harmful to them. If it is I could just wait until spring to put some sand in the tank. Was just looking for some answers
Thanks
