How can I accelerate purple coralline algae in my saltwater fish tank without useing caribsea purple up????

Answer 1

first, purple up sucks.

second, as long as you're maintaining proper calcium, alkalinity, and magnesium it'll catch up in time.. the first few months are slow as h**l but once you hit the six month or so mark it'll take off like a rocket..

if it's an older tank i'd take a look at you tank readings, and get rid of anything like sea urchins that'll eat coralline

Answer 2

Good lighting, good water conditions and good water flow.  When I bought all my live rock, it was mostly bare, but I bought a piece with good coverage, turned off the filter and power heads, I took a plastic knife and I scraped the algae off the rock all thru my tank and let it settle for a few hours, before turning everything back on, it seeds the tank if you will, now I have so much I am cleaning it off the glass every few days.
