Did you try and stop dosing Prodibio ? I had faced algae issues with that, after stopping no algae now at all.

For calcium i use purple up few drops of it thats it...

What were u dosing in prodibio ? And u stopped ??

Biodigest and reefbooster. As of now dosing only calcium ( Seachem).

Ohhhkie can stop reefbooster but biodigest and prodibio is both hand in hand product .... If need be i have to stop both the products....

Everything looks nice, how about a FTS

Purple up is Calcium/Aragonite in situ. Here is 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.

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. "

The link is not opening bro.... And thank you for the detailed explaination....

Thanks this was informative

I am not a chemistry guy
But to cut the thing short and from what i understood it says

I can dose calcium or purpleup in my freshwater container and then dose it via manual topup that i do everyday.....

So does that means dosing seachem part 1 and 2 also in this way is benifocial ??

Thank you once again

I would say to not use Purple up at all.
You can dose the alkalinity part and calcium part directly into the tank water. Make sure you add the alk part in a high flow area though so that it doesn't cause a localized ph fluctuation. I use Randy's 2 part in a similar way, around 100ml of Alk and Calcium everyday. Works fine.
