Ok just dirted my tank and i was wondering if it's ok for me to put my fish back in the water? I used dirt i had previously soaked and dried(repeat x5) from a couple months ago and just put the water rocks etc. back. I won't hurt my fish if i put them back will I? It was around 5 hours ago. Should i wait till the cloud settles? Will i have a chemical spike? Sorry if this is is in the wrong section.
