What kinda algae?

[DTz]

Hi..can u guys pls help identify the type of algae? And how I can get rid of it?

Nitrate is around 10. Po4 undetectable according to hannah ulrs. Corals are doing find. I do run an algae turf scrubber.

Looks like the start of hair algae, kind of indicative of your undetectable phos

could it b dino ... some of the algae on top of rocks has bubbles on it

 

[ahiggins]

No, dinos are more long/stringy and not uniform. This looks hairy and dinos are slimey.
How old is the tank?

the tank is 1 year old .. i recently had a green slime outbreak and used chemiclean to clear it. and prior to the outbreak i was dosing no3po4x which i stopped. this brown algae type has been there for 1-2 mths. but since i got rid of the green slime and increased my lights intensity and hours, it is getting more serious. so far sand seems ok ... just some small dark brown powdery patch. since increasing my lighting intensity and hours. coral has been thriving and colouring up. my fishes all seems healthy besides a few ich spots recently which went away pretty quickly . no fish died or showed serious distress. hope the information helps. thx

Turbo snails will eat it, as will pincushion urchins, although I have trouble keeping the urchins alive for long.

do u have the name for this algae? n u sure its not dino?

I'd say green hair algae from what I can see.

Definitely gha, although no phosphates on a Hannah ULR is concerning and could lead to dinos.

For your algae I recommend first turning down the light intensity and duration until it gets more manageable. More light always means more algae. With phosphates undetectable reducing the photo period and intensity will help prevent dinos too.

While turbo snails and urchins will eat gha, there are other options that are longer lived, more hearty, and won't eat everything to the point of starving themselves. A little bit of left over algae is a good thing. I recommend trochus, cerith snails, and gold ring cowries. They have down well eating gha in my tank and live for years if properly looked after with a little algae left over in the tank.

Additionally I recommend dosing inorganic sources of phosphate like Seachem Flourish to help reduce the risk of a dino outbreak. Maintaining 0.10ppm is a good starting point and adjustments from them can be made for your tanks needs. Corals do like phosphates too.

po4 is at 0,03 the last 2 days i checked. no3 around 5-10. fingers crossed lets hope its not dino.

btw.. my tank is a 130 gallon. how much of seachem flourish shud i b dosing? thanx

Follow instructions on the bottle at first and retest the next day. If target is not reached, then increase dose by 50%.
