dosing purpleup
 

Do other coral benefit when dosing with purple up Ca? or is it really only meant for coraline algae?

Its good
 

Purple up is ok. i used it exclusively for the first two years, but i found i still needed more supplements. coraline Requires pretty much the same stuff, and by regular doses of ca And kh It will do the same if not better than PU. you cant adjust PU To your absorption rate And thats where you may find yourself alternate dosing With what ever element is low.

It contains Iodine which corals like, but wouldn't confuse that with an added supplement. Also likely contains small amounts of strontium and magnesium. Basically it is calcium thou.

Ah
 

Explains why it is hard to keep kh High enough. i had to start dosing Builder every second day, then went to calcium advantage to replace the PU Altogether.

Honestly, save your money. Maintain a stable level of alkalinity and calcium and the coraline will take care of itself. I have never dosed it and I have ample, in fact it is a problem! Any anyway, if you can see the liverock that just means you have room for more corals :mrgreen:

I went and bought some Tropic Marin Bio-Calcium. I think it's made by the same company who makes Zeo products? It costs a bit more per gallon in the long run but if it helps my tank so be it.
If anyone uses this can you share what you think of it?

Use this product to raise your calcium to 425+/-. As it appears you do not have a calcium reactor, use a daily 2-part additive (such as B-Ionic or a comarable product) to maintain your calcium and alkalinity. Your coraline algae with come with time. Cheers.
