Purple Up - How long until it makes a noticable difference?

[jasno999]

How long doe it take before purple up really starts showign a dramatic difference in coraline alage?

PurpleUp is mostly just a ca additive which can be achieved with other ca additives just as well for less. Since you are adding ca make sure you have a ca test kit and alk test kit to keep it close to 400 ppm and 8-10 dKH.

See ”Understanding Calcium and Alkalinity”

Your lr has to have some coralline algae present now for it to spread.

Growth is going to depend on how much coralline algae you have now, water quality, and lighting. Could be as short as a couple of weeks to a couple of months.

Thanks.

I have coraline already.

HAve the CA test need the ALK test kit.

Will get what is needed and the rest will hopefully take care of it self. I am hoping for some noticable growth in a month or 2. I want it to start growing on the glass and what not.

Don’t worry, once it starts it’s pretty steady. Soon you more then likely will be hating it due to it overtaking everything.

You`ve got that right. I used to not have much and now I wish I could get rid of most of it. Looks good on the rock but that GLASS.

You will eat those words

Ok maybe not then

I have green coraline growing on my back glass. I also have spots of purple and pink. I keep the front 3 sides cleaned up.

Hoping not to hijack, but what causes the differnt colors?

[Brenden]

IME Green is usually the predecessor to the purple/pink.

Dumbutt or no, I bought a bottle of P/U a week ago. I swear, I can already see some new spots of purple on the rocks. The product seems good although I realize I may have to test for whatever it's adding.
