I know this has been answered a few times as I did a search 1st before posting hah. I had a few questions to try to make sense of the information I gleaned from my search. I appreciate the patience! I have a 75g tank and added new PFS. I did rinse it beforehand, albeit while on a conference call with work clients, so my attention wasn't as focused as maybe it needed to be. I thought the water was running fairly clear from rinsing, it has been roughly 14 hrs now and it is still cloudy. It definitely is clearing up as I can now see through the tank, but it still is pretty cloudy. From my search it seems that while some people don't experience cloudiness that it is normal for about 1-3 days? I want to take care of it now before any filters or fish go into it. From my search it seems 1 option is to just change out most of the water and then add some chemicals I can obtain from the local petstore and that should clear it up. Is that the best way or is there another way where I don't have to dig out all the sand and rinse it again? Haha. Thanks guys
