View Full Version : Brownish red build up on SPS in high flow

My SPS which are lined up directly with the power head are getting a brownish/red growth on the side facing the flow. It builds up everyday and I end up spraying it off with a baster. It keeps coming back. Algae or bacteria growth? Any remedies?

I would say probably some algae caused by nitrate and phosphates.
I had some grow on my birdsnest and my nitrates and phosphates had gone up.
What's are your parameters

It's bacteria. Cyanobacteria or dinoflagellates.

I would say cyano.

I get this red cyano I'm The cornes where there is low flow. I syphon it out when I find it. It's re occurring. Maybe it's this red cyano. Should I do a black period? Kill it off?

Would something like this slow build up on the sps be serious enough to do a black out without light to kill it off? Maybe I'll do a water change and if it doesn't get better then a black out

Cyano. How long has your tank been up? Might still be cycling. Sounds like the powerhead is blowing it around the tankard it's landing on the SPS.

Change some water and figure out how to get your nitrates down.

Do you have have sand? What kind, and how much, live rock do you have? How old is your tank? If you do have sand, used real live rock and have enough of it (not a minimalistic scape), then after about a year, your tank should be able to handle nitrates all on it's own unless something is up.

I do have about 25 pounds of sand in a newly migrated to 7 gallon. The live rock is going on a yr and a few months but the sand is new

So I guess that's the downside of missing an established aquarium to a new tank, the sand will always got cyano?

I'm not sure you can fully avoid a cycle by doing that. I did one 75 to 125 and it still cycled. Not as bad, but still had a short period of cyano.

It's your unbalanced nutrients imho. Get those nitrates lower and you should be fine. They will smother the coral though. I find dosing g of good bacteria to be very beneficial to getting rid of cyanobacteria.

What good bacteria do you dose?

I have dosed many and continue to dose different types of bacteria. Right now I'm dosing bio digest. I have had a great response from my tank while using it. I have also had good experience with Dr Tim's waste away, microbacter7, fritz and others.

Odd place to get cyano or any type of build up- at the point of maximum flow..
But it does fit with your current situation..
What happens if you redirect the power head so that it's not hitting the corals?
A pic would help but it certainly sounds like everyone is on the right/same track..

A pic would help but it certainly sounds like everyone is on the right/same track..Anything that is not in direct flow is just fine. So the problem got worse. Anything in the flow with some build up is starting to fade and die off, tuning white... including my large Monte colony Wich I'm upset about.

I did a 20% water change. I'll give the during bacteria a try. Sounds like it would make sense.

Corals getting browned out could mean alot of things. Could be
New tank syndrone
Stability
Lightning
Phosphste/nitrate high
Flow

Sent from my GT-I9192 using TapatalkIt's not actually Browning of the coral overall. It's a brown algae film build up on the side facing the flow.

This set-up is not new, only the sand. The current live rock, coral, etc is pushing almost a year and a few months old. These are my water parameters today.


Aug 18th:
Alkalinity 8.0
Phosphates .04
Mg 1360
CA 375
Salinity 1.026
NO2 0
NO3 undetectable

Sent from my Pixel using TapatalkYour nutrients need to be in a good ratio N03 to p04 as well as bacterial supplementation.

Ai hydra 2600 and two hydra primes. The hydra 2600 and one of the prime are positioned on the right side of the tank with the sps. The lps live on the left side with a single prime. Lights are about 9 inches above the water. They come on at 9:45am, slow ramp up. The lights don't hit full power until around 12pm. Then a very slow ramp down after 1:30pm. The lights get pretty weak around 6pm and shut off at 8:30pm.
At full power:
-All blue and UV spectrums on 100%
-White 44%
-green and red hit Max on 5% mid day otherwise they are off

They're good lights. I use SB reef about 15" off the water. I run my blues st 100% for 10 and whites at 25% for 4. I'm thinking the hydra would be stronger than my lights. Is it possible they're getting too much light? Or maybe too much white light.

I was afraid of that and looking at other people settings mine may be a little bit too strong
