Hmm, starting to see a pattern. anyone else want to corroborate??

Update: As of today, I can see quite a bit more PE than previously. Wayne (rice reef) was just by with his macro lens and we can see PE on almost every piece.
Today my alk was 6dkh, so this follows along with my thinking high alk affects PE. However, I've also reduced my zeo dosing and have been adding a bit of potassium, so I can't be sure the exact reason, although my prime suspect is the alk...

Interesting conclusion. It make sense after reading all that thread. I never wonder why I had such good polyp extention. It was there and I thought it was the norm.

I have a red planet frag in direct current and there is bearely any polyp extention although it's growing and incrusting at the base. I think a strong direct current is not helping either.

Also sometimes I had my alkalinity go higher and it did not affect the extention. Once it was at 12 for a white until I calibrated my dosing pump properly. Now I keep it between 6.5 and 8.
