What am I missing here?
I'm just trying to understand how readily people see SPS growth increases when the pH rises, all other things being equal.
So the increase in growth is more likely due to tje increase in ph? Better colors from adjusting alk?
Color is very complicated and I personally don't know that alkalinity directly matters that much for color unless the alkalinity is too low. Other factors may predominate color issues in many tanks.
For some corals, it is known that higher pH accelerates growth and that low pH slows it, which is one of the reasons why people are worried about coral reefs and acidification from global CO2.
I've consistently noticed better color with lower (7-8) alk and consistently noticeably better growth with higher ph. The trick is having both at the same time I've managed both with a co2 scrubber the media only runs me around $15 a month and it seems to be worth it for the amount of growth I get.
I see. My pieces have really took since some tweaks in parameters.
I believe colors have improved since I lowered alk. I was keeping alk at around 10 with low nutrients. Seems corals were getting burned. Now that I'm at 8-8.5 colors are looking much better...and still improving
Would be interesting if folks who do not have low nutrients see the same thing with respect to color and alkalinity.
