I had phosphate leaching for about 6 months. But honestly, a 4 lb container of GFO more than makes up for the savings in rock and the lack of hitch hiker crabs haha.
I went with marco rock so it wasn't as bad as some. From what I've seen with others, Pukani is your biggest offender. I think it's worth the risk though since Pukani is possibly the sexiest rock in the industry.
Unfortunately … BRS couldn't ship it across the border … and there was nowhere to buy it when I set the tank up two years ago. I really wish I would have known about Eli selling pukani back then.
Oh well, next tank I guess
