Zeovit & coralline algae

[Skipper]

Do you feel there is a correlation between using the Zeovit method and a lack of coralline algae? It seems that many of the tank photos I've seen of Zeovit users are somewhat lacking in coralline. Is this correct? Any speculation why, if this is true?

Skipper, coralline isn't the only algae that doesn't grow in a ZEOvit tank It's due to the lower KH used[6-8], NSW levels of the elements, & lower nutrients availability. Bob

Bob, any negative effects of running an elevated KH of about 9 so dat coralline will still be abundant? I dunt think the corals will be affected by the higher KH too rite?

oddly enough I keep my Alk. at around 7-8 and have noticed an increase in my Coralline algae which is good for me as I would like better coverage on my rocks. This seems to go against the status quo of what most people are finding but hey it's good for me at least.

I love colline coverage on Rocks but I hate on glass. :-)

Farish, higher elements in the nutrient-poor environement may bring consequences for our corals. With higher KH levels with ZEOvit, it might be advised to run a slightly lower salinity[1.023] with a slightly higher Ca level for elemental balance. Bob

Once I had Mg stable, and I started to dose Sr, coralline growth is taking off big time in my tank...

I have read from other reefers on RC, that Sr may be a big factor in coralline growth, and I personally have found this to be true... For years it was thought that intense halide lighting discouraged coralline (which may be a factor), but it's looking more and more like Sr may be even a bigger factor...

BTW, I have been dosing with Kent's Strontium and Molybdenum in very low doses...

Todd, with my old tank when I started dosing Strontium I noticed a major increase aswell.. I was thinking of starting to dose Strontium again myself..

I have zero coralline in my tank, it all turned white and flaked off.

[Aged Salt]

Zeoheads, be careful with prolonged, excess accumulation of Sr. One with Molybdenum which has been implacated with algae growth &the other with coral skeleton brittleness & thinnes of the radial coralites. Bob

I noticed something last night.. I switched over to xm20k bulbs and since the switch my coralline has started to grow again.. What temp are you guys running for bulbs? I was runnign CV 14 and 20K beofre.. These bulbs were really white compared to the XM20k.. The xm20 seems to be an awesome bulb when run off 400 because it looks great and has good par aswell... The corals are coloring up much better also...

bob,
do u add sr. at all?
