Good morning Shane. Newbie to SPS here. I just found this thread.
Curious on the RODI thing. To be honest a lot of times I see my TDS meter reading 1-2ppm and just roll with it. Sometimes immediately after changing filters it's 1-2ppm. That said, many times it does read 0 ppm.
My acros are growing just fine, save a few pieces (I have like 20 dif acros at this point). However, I've only been in the game 4 months or so. I'm doing monthly ICPs and haven't seen anything concerning.
Curious if there's anything untestable to worry about in RODI? Or do you think ICPs should cover it. One other thing - I think my polyp extension kind of sucks. Even for acros that are growing / puddling nicely, I feel like vendor pics show much better polyp extension.
Love your acros and collection, I actually have an SBB prom queen and it's one of my favorites!
Thanks!
