I don't know about the article. But I read a few posts here saying NOT to rinse it or you lose like 50% of the volume. Didn't rinse the flourite at all
, just placed 2" of it into my 10 gallon. Filled the water slowly up using a plate. Yes there was initial cloudiness. Yes I was worried. But that cleared up within a day. The following pictures are from my tank.
Placed flourite, planted plants, and slowly filled up tank. Cloudy
~24 hours later. Cloudiness almost all gone. Didn't even use a filter as you can see. Just had the bubble curtain going in the back to promote circulation
Week later. Added new plants which disturbed substrate, however, no more cloudiness. Never
ran a filter. Only did daily 10% water changes while trying to siphon out the brown dust as mentioned in the OP's link.
I'm pretty darn happy with flourite for the amount I paid, $15/15lbs. Cheapest "good" substrate IMO.
