How long... coralline algae

[Rmckoy]

We all can’t wait for coralline to start
But when it does and it has to be scraped from the glass with a razor it’s not that desirable .

give it time .

The water will never boil as long as you’re watching it .
Rome wasn’t built on 5 months .
neither were reefs .

Mine took about 6 months before I noticed my first little spot. I never purposely added it, and I'm far from knowing what I'm doing, but It seems to be spreading on this wall quite nicely now. I clean my glass but I'm letting it go on the divider wall. Tank has been running now about a year and a half.

So, I discovered the reason I have no coralline. I bought some new frags, and on it came some coralline. Soon after my swarm of amphipods attacked the frag plugs and cleaned it of all the coralline.

I bought a wrasse to deal with the problem. So hopefully I'll see some improvement soon!

Seed your tank with scrapings from a established tank

when it takes off , you will have tons to spare

Never if your dosing Vibrant.

My tank barely had coraline for 3 years even with alk around 8 and ca at 450+. Issue was pH. It used to be 7.7.

After I fixed ph to 8.3, my coraline exploded and covered the tank rocks on 4 months.

I also elevated alk to around 9.5 since I started keeping SPS.

I'm curious how did you adjust your pH?

High co2 concentration was main reason so I installed a co2 scrubber. However this only helped partially - brought it too around 8, 8.1 - bc the DT surface air and overflow is still exchanging the "higher CO2 concentration" air from the living room.

So then substituted my alk dosing from the Redsea B (main ingredient is basically bicarbonate) to using DIY soda ash, which is basically sodium carbonate. Bicarbs is ph neutral but carbonates raise PH. This pushed it to 8.3 during the day.

At night it still falls to 8.1 to 8.2 but I'm OK with that. When I bring my fuge back on line it will help even it out a bit.

About 2 months and I had dots all over the place. I dosed Kent corralline fertilizer. Not sure if it was doing the job but I had an explosion of growth at one point and my back wall is thick with it. Growing GSP over.
