Why no corraline algae

[ReefkeeperZ]

Ultimately, stability is more important than actual levels, but you must be within acceptable levels for your tank conditions for that to be true.

well said, I completely agree with this.

even if I'm on a different line of thought than other long time reefers, I have been doing lps/sps for a long time, I couldn't agree more that stability in a tank is by far the most important factor as long as you are in the acceptable range.

I do want to point out that his question was about coralline growth. and the original question said nothing about SPS. I simply replied on my thoughts on how to increase growth rate for coralline.

and there are definitely higher light species of coralline algae, but like I said generally a lot of coralline species are medium to low light, there are species that adapt or do well in higher light and lots of high light tanks have had those introduced and it flourishes.

Yes. You are quite right. Sorry, I didn't realize that there was no mention of the op not being able to keep sps until after your post about raising alk. I, of course, read the whole thread and responded.

Kent strontium and molybdenum accelerates coraline algea in my tank. I use 5ml a week on a 40 breeder. However, like others say, it may not do much for your sps.

are you testing for strontium and molybdenum?

I am not.

With a lottery of 1000s of species ending up in your tank, I don't think there is a single answer or that one persons experience can predict anothers... but as everyone has said, a stable tank that can grow coral will grow coraline.

And yeah, the standard advice is always do not every add anything you do not test for. In most cases "I added X nutrient" and something occurring without testing is simply coincidence.

are you carbon dosing? ie, nopox?

i experienced severe sps tip burn (then tips covered by algae) and lost quite a lot of sps frags and colonies. I was maintaining my alk at around 9-10 dkh using DIY kalk dripper together with manual dosing to top up my levels.

after reading up on forums, i set a lower target of around 8 dkh, and swapped to 2 part with a doser that spreads the dose out 24 times in a day.

currently tank is holding steady at 8.5 dkh, 440 ca, and 1300-1350 mg. SPS are finally not dying, and some looks like they are gearing up for some insane growth.
