Yeah I caught on what you were trying to sayOops! I edited my last past because at first I mistakenly said it takes a long time for PykanI to cycle. I intended to say cure instead of cycle.
Yeah leaning towards cycling it in a bin. Partly because if I do get a bloom it's easier to clean out. How did you clean your diatom bloom off the rock?With a quick look, I couldn't find a good answer on curing Caribsea's South Sea Base Rock either. All we can be sure of is that it is indeed natural rock, so could have dead organics, unlike manmade rock, which is really the only option to be sure that the rocks are free of organics. So, I might just check by soaking a few pieces in a bucket or RODI for several days, then run a phosphate test. If you really want to be 100% sure the rocks will leach zero phosphates in the tank, you're only option would be to cure in another container. That said, I went with natural rock too, but chose a less porous type, (Fiji), and knowing there was less space for organics, took a chance that the rocks would cure in the tank while it cycled, with lights off. We had zero phosphates when the tank was cycled, and never had an algae explosion during or after the cycle. This is not to say that we never saw a diatom bloom, where rocks and sand turn an ugly brown, (but clean up easily.) This is normal in new tanks, even with cured or manmade rocks. It's known as the uglies and it should pass fairly quickly.
I think I was just asking because there are so many more crannies in the rock vs a freshwater tank were it's a lot more flat surfaces.I already love your scape. Seriously, the one above has it all... high spots & low spots, swim-throughs and nooks and crannies, as well as something I overlooked with my own. That is, space in the sand to create little islands for gardens of zoas, acans or rock flower anemones. I can already see some nice euphyllia waving around on that scape, maybe about halfway down your slope.
Diatoms are child's play compared to other baddies like dinos, cyano, or tough deep-rooted nuisance algae. It's almost like brown dust with how easy it comes off. So, a toothbrush for a light scrub, a turkey baster to blast rocks, and a decent gravel vac would have the tank looking new again in no time. During the diatom peak, they'd reappear a day or two later, but we'd leave it alone until the next water change. It wasn't hurting anything but our eyes, and we're always glad to save on salt. If I'm not mistaken, the diatoms had exhausted themselves and quit reappearing before month 4.
I'm nervous because I'm really happy after only one night of playing with it.
