Tiny Cories

Dennis, it isn't just 'rainfall' we're simulating but also an increase with dissolved oxygen and extended wet/dry activities that cools without a chiller. That said, yeah, the Gex will serve it's purpose, although personally, I would have used a 4-5w powerhead since higher wattage equates heat that's transmitted back into the water column.

FYI, I'm fiddling with about 60 hastatus fry...

WWWoooaaahhh..!~ I'm duly impressed. I have no luck yet. Might just pop the Gex internal into my C. Hastatus tank and see if that helps.

On another note, the Gex internal filter I am currently using is an e-Roka PF-201, which is rated for (not sure what it means) 4.6/3.3W which is relatively low and below your recommended.

Dennis, the 4.6/3.3W discrepancy is due to 'electrical cycle' difference between 50/60Hz. Our mains are 50Hz but I'll let more knowledgeable members elaborate on that.

The tiny pinhead of a fry are doing well and 60 is a very conservative number since I spotted fry in other tanks as well. If all goes as planned, I *may* decide to rig up a 4ft low with a 800-strong shoal of hastatus... something I've always wanted to do... *must remember to take my itch meds...*
