wasp Posted October 31, 2006 Report Share Posted October 31, 2006 A while back someone posted part of a study showing that sps growth rate is increased at increasing pH levels. Who was it I'd like to see that again? There was another about the relationship between alkalinity & growth, but it is the one about pH and growth I would like to see. Anybody can help?

dogmatix Posted October 31, 2006 Report Share Posted October 31, 2006 was it a GARF article ? Just had a look it wasnt that but something similar. Quote Link to comment Share on other sites More sharing options...

wasp Posted October 31, 2006 Author Report Share Posted October 31, 2006 Layton you pretty upset about that, huh? Really it was just a joke, and the 20% of the time you are NOT thinking about zeovit, I wouldn't have a clue what you are thinking about. There is no trick. But hey, I CAN tell when a guy can't spell :- Quote "put you're mind reading...." Was it you posted it by any chance I know you did the alkalinity one? And thanks for the help Dogmatrix it may have been Garf although it looked a bit more high tech than most of their stuff. Oh well, not a major if i can't find it I know the main thrust of it.

cookie extreme Posted October 31, 2006 Report Share Posted October 31, 2006 but it is the one about pH and growth I would like to see. what do you hope to find? that a higher PH increases growth? if thats the case i better lower mine to 7.8 from 8.1 maximum.

wasp Posted October 31, 2006 Author Report Share Posted October 31, 2006 There was a quote from an article saying growth increased by 25% for each 0.1 pH increase starting at 7.8. Unfortunately I did not read it properly at the time i was hoping to find it again. Quote Link to comment Share on other sites More sharing options...
wasp Posted November 1, 2006 Author Report Share Posted November 1, 2006 Well Cookie pm'ed it to me, how he found it i don't know? I used to think Layton was the king of search! :lol: Anyhow it's a good read for people wanting to set up good conditions for growth, so here it is. For some reason the last little bit doesn't work right so it has to be copied & pasted to your browser. http://www.agu.org/cgi-bin/SFgate/SFgat ... hits=200&="OS21N-03" Quote Link to comment Share on other sites More sharing options...
puttputt Posted November 1, 2006 Report Share Posted November 1, 2006 I'm with cookie, my ph barely gets above 8 - ever - and my growth is crazy. Don't really want another 25-50% growth rate!!!! Quote Link to comment Share on other sites More sharing options...
lduncan Posted November 1, 2006 Report Share Posted November 1, 2006 I used to think Layton was the king of search! :lol: It's hard to find stuff if you don't look ;-) (3rd hit on google with "coral ph calcification 25%" ) Just keep in mind, that's it's one abstract, of one study. Some parts of the abstract are a little ambiguous. Although at face value it makes sense. Less protons to pump in calcification when the pH is higher I guess? I have another independent paper (full text, not just abstract) which shows a linear relationship between bicarbonate additions and calcification rates, which also shows the same relationship between pH and growth (25% for an increase for each 0.1pH unit increase) Quote Link to comment Share on other sites More sharing options...
wasp Posted November 1, 2006 Author Report Share Posted November 1, 2006 Well wish I was like you guys I'd like a bit more growth, although I did have to throw some pink monti bits in the garden last week after failing to give them away. Some of the ones I wish would grow faster are only pretty slow though. Quote Link to comment Share on other sites More sharing options...

In fact I've broken the zeovit rules over the last few weeks and bumped alkalinty up, first to 10, and then to 12, just for a try. It was immediately obvious there was more new growth at the tips. However i got some strong advice from the zeo gurus that i'm asking for TN to do this in a zeo tank, so have returned alkalinty to 8.0 Had a nice burst of coraline too.

reef Posted November 1, 2006 Report Share Posted November 1, 2006 Well wish I was like you guys I'd like a bit more growth Remove more acros. Too many coral will slows your growth. The guys with great growth have hardly any corals. more space means better chance of faster growth, but you will sacrifice some colour as corals cant do both very well as it take too much energy Dieter Brockmann wrote a book Fishes and Corals and found that at a ph 7.7-7.8 lead to immense growth rate in hermtypic corals. My ph is between 7.7-8 and found that i great growth if i keep calcium and kh levels at a consistent rate. like cal at 400ppm and kh 9-10 Quote Link to comment Share on other sites More sharing options...

puttputt Posted November 1, 2006 Report Share Posted November 1, 2006 Pretty happy with my colours altough not as intense as say Craigs. Do have excellent growth with good large colonies. Welcome to come and have a look Reef, before its pulled down for the shift. Tanks looking stunning at present - typical. Quote Link to comment Share on other sites More sharing options...

Like every rule in this hobby though, there is always someone who is breaking it & getting great results. Puttputt, I would like to try & squeeze in a visit to check out your tank before the opportunity is lost. Could you pm me your address & phone number? And Layton, I'll hand it to you THIS TIME ONLY, your post was funny! :lol: Quote Link to comment Share on other sites More sharing options...
