Will algae always outgrow coral growth?

[snowlynx]

I have a jack o lantern and it's spread beyond the radius of the frag plug.

The rock it's on has green algae all over it. Will the coral grow over the algae
or growth stunted?

I don think it can grow over algae.

Depends on the kind of algae and how quickly it's growing, which in turn depends on lighting and nutrient availability. If you have fast growing hair algae, you will need to mow it regularly until you fix the nutrient problem that enables its growth.

I removed all fish few days ago so corals only now. Hoping this cyano or diamtom bloom and green algae will go away.

I am using RODI, 0-5 TDS

White LED's on 4 hrs/day

Nitrate 0-5
Phosphate 0-5

Maybe blackout the tank for a few days?

Well the coral definitely wont grow over algae...but the algae can grow over the coral. You have quite a bit of algae...do you do water changes? Skimmer? Amount of fish/tank size?
Additional details can help others give you better advice.

If your getting 0-5tds with fresh made rodi that could be contributing as well. When was the last time you changed the filters? It looks like it's time to do so.

Yes, blackout for few days, not really by choice. Darn ebay wifi reef black box,
wifi keeps cutting out, app cannot find device. The crappy part is when it loses
wifi, the white lights kick in light like 80%!

I was awoken to bright lights at 3AM. Replaced the wifi controller they sent me already.

I am running a skimmer from start. The rock piece shown in photo is Tonga shelf rock
from BRS. I did not cure it so not sure if it is leaching phosphates. Tests show low to 0
nitrate/phosphate.

RODI 0-5ppm TDS should be normal. At least what other posts here, that range is
fine. 20% water change last weekend, did read 0 TDS.

I think the FE threw everything off as well. Still running carbon and chemi pure blue

 

[snowlynx]

will wait it out few weeks, see how things go. I have been using the Redsea nitrate/phosphate stuff, not sure if that would cause diatom bloom again.

 

[snowlynx]

one quick question, skim mate is now translucent white color. Is that heading to danger zone of corals not getting enough nutrients?

no more fish, so no more fish food or fish waste...

 

[crawlerman]

Corals need nutrients, but it looks like you have plenty. What are your nitrate and phosphate levels?

 

[Sk8r]

Getting a gfo reactor and running it with monthly media changes will solve your algae problem and let your coral grow. GFO removes phosphate from your water, and corals don't like phosphate, while algae need it.

 

[snowlynx]

I am using the API tests

Nitrate 0-5
Phosphate 0-5

Can't say for sure it's 0, so I say 0-5

It is definitely not high levels

I'm looking into the BRS GFO.

 

[sde1500]

0-5 phosphate isn't even worth testing. That's a terrible range. 5 would be like catastrophic levels in a tank, but 0 isn't great either. You need a better test.

 

[LeJeune981]

Api Phos test does not have that kind of range...

0. And 5. Are wayyyyyy differant colors..

I'll post a pic

Zero is yellow.... 5.0 is blue
Huge differance

Ok, but the interesting range is all between the 0 and 0.25.

Agreed... I'm ordering a sailfert test kit in the coming weeks

You are correct. I should not have said 0-5.

So mine is light golden yellow, lol, I don't know what decimal range that falls in.
0-.25ppm?
