coraline algae

Purple Up works for me my coraline starting growing on rocks after month one if dosing it took the month go see benifits but after that it grew like crazy and my tank was only 8 weeks old so if it worked for me I should work for anyone I think people say it don't work cause they don't give it fair time to prove itself if u can wait 2-4 and dose everyday those days you'll see purple or pink spots starting on your rocks at least I did just had to rose it faithfully for a month not to say its the best way but it most definitely worked for me but kalk is a cheaper method I'm sure and will work also but at marinedepot.com u can get a 16oz bottle of purple up for $12.99 at least that's what I got it for 6 months ago but you do have to seed the coraline by putting a live rock or something with coraline on it already as it doesn't seed it but it accelerates growth I'm sure there's others that hate it and everything but it worked for me like I said its worth trying my opinion just gotta be patient for a few weeks but what I did was use up the 16oz bottle then switched to kalk drip when it ran out to maintain and continue growth but a person could continue dosing it alone as it has many of your main trace elements so it saves having to buy a bunch a different bottles of the other stuff also anyway just my 2 cents worth on my experience with it

There have been numerous threads discussing purple up and why it really will not work in an aquarium due to the composition of it in relation to the pH of the tank water. These statements are not mine but from professional chemists who volunteer their time on RC to help us better understand water chemistry.

A water change using a good salt mix will provide trace elements as well.

That's very good info, KafudaFish! Please provide the link. I would like to take a look and learn more about the PurpleUp.
I've never used PurpleUp and I don't think it would be necessary, but it's good to know that not all the products out there are doing what it claims to do.

I've noticed that when I do my water changes the coralline algae tends to get more vivid and grows a bit more during that week. It could be that ionic balance from the salt addition (Ca/alk). I never thought about the trace elements though. That's new to me. It kinda makes sense.

I would love to read more about trace elements and coralline algae as well. If you have any articles I'll appreciate very much.
Thanks,

Grandis.

Some people do claim that Purple Up increases coralline. It might be real, but not because it is supplying calcium or alkalinity. As mentioned, the fine aragonite cannot dissolve in seawater at normal tank pH, despite claims otherwise. It might be a placebo effect (i.e., not real), it might be due to other ingredients, or it might be somehow due to the particles of aragonite acting as locations for coralline to start growing. I don't know which it is.

In general, normal alkalinity and calcium, highish magnesium, and low phosphate and organics are likely to promote coralline.

From this thread:

Purpleup has come up here in the Chemistry Forum many times in the past as perhaps you are aware. This is a quote from one of Randy's past posts:

"I do not recommend it for most people.

It is not a useful calcium and alkalinity supplement. The main ingredient, the fine aragonite, cannot dissolve in seawater and is wasted, as I showed here:

Calcium Carbonate as a Supplement
http://www.advancedaquarist.com/issu...y2002/chem.htm

Other ingredients may or may not be useful.

It disappoints me that so many companies continue to push products with the main or only ingredient being fine aragonite (sand). Either they are ignorant of seawater chemistry, or they don't care that the product doesn't work as described.

I would back off such assertions if any company selling any of these sorts of products could show a single thriving and growing SPS type of tank that could be maintained long term using any dose of Purple Up as the only source of calcium and alkalinity. I do not believe that any well known RC member has ever claimed to have done that either.

The particles of calcium carbonate in Purple up and other products may be so small that they can stay suspended in solution. If they do, they will dissolve during the very low pH part of an alkalinity test, and give a falsely high alkalinity. Calcium kits might also be fooled.

In any case, they will not dissolve in seawater. Some portion of them may dissolve as they get into low pH areas, like deep in a sand bed, just as calcium carbonate sand itself will.
But the water column of a reef aquarium is supersaturated with calcium carbonate, precluding dissolution.

FWIW, I have debated these issues with company reps (like Kent) online here, without ever having them provide any evidence that their product (in that case, Liquid Reactor) is any different than adding fine sand.

Think about it. ;)

Purple-up contains finely ground aragonite (reef rock), which does not dissolve unless the pH is lower than 7.8. When you add this stuff to your tank water, it is skimmed out very quickly. Even at a pH of 7 to 7.8 the rate it dissolves is very slowly, certainly not enough time before it is skimmed out. What possible benefit can it have? :)

This one does not go into specifics but it does show the opinion of Randy:

There are others that I have read over the years too. There is one other recent one that may give a better explaination and I will see if I can find it.

You may want to look through the chemistry archives and see if anything catches your eye.

I sure appreciate your help!!
Thanks a bunch, KafudaFish!

I have noticed i put a piece of fiji rock i acquired with a little coraline algae on it and sure as **** it has spread all around the zooanthids which has caused my zooids to start moving and reproducing something fierce....

Perhaps that's not coralline algae.
Pic?

This is my purple lava. :)

I do not use KALK, I have recently started dosing 2 part as ALK and Calc consumption is substantial in my reef. Every single rock is encrusted with coralline which uses up a lot in addition to my corals.

I notice my zoas dont spread above coraline, it this normal?

when my zoas approach coraline, the coraline goes white, and then the zoa grows over that white area, and then again, and then again. Did you mean yours are doing this, or are they not growing at all onto coraline?
