[mic_1011]

tank is a 125 with 40 sump been running healthy for about 6 months. plenty of green algae but no coraline. calcium is at 420. do i have to introduce some? what do i need to do? running 4 65w power compacts 10000k and actinics 5050

dude the coraline is just around the corner , dont forget the magnesium to help stabalise the calcium , i use kent calcium and coraline is everywhere big time

 

[mic_1011]

what do you mean? what corner? lol
i haven't even added any calc. lfs tested my water and told me 420

Doesn't the coraline start out as green on the rocks (like you said) and then start turning purple? Or is that 2 types of algae?

Tank needs to be seeded with some rock that alreay has coraline.

Sent from my SPH-M910 using Reefs

That's what I thought. Have to get my hands on some

Coraline feeds off of mag . And if you dont have a rock in your tank that has coraline on it you will never get it

i got my coraline after dosing with mag and cal and two med pieces of rock from manhattan aquariums!! but if you need coraline to grow from a rock then how does coraline begin in the first place???? ( i mention the rock cause other than dosing, it was the only other thing i had added)

and the corner is just a time frame , it took me 6 months to get rid of hair algae and slime before i noticed the growth begining

It is faster to 'seed' a tank with coralline scrapings from a rock that has the color coralline you want (it does come in a number of colors), than to just wait for it to develop naturally.
..and your parameters should be spot on to help it grow quicker - Ca, Alk & Mg.
Higher flow is also said to help increase coralline growth.

Do not use a product like Purple Up - as that will throw your parameters out of whack as it is not balanced.


...think of it this way - you earn coralline by keeping your water parameters in great shape

High mag steady steady alk and cal and tons of flow I hav Lotta coraline more in my sump under pc crap lights than my 2 x 250 watt halides. It takes an established tank to have coraline just my opion and what-if noticed
