help needed on green algae

[jowenteo]

guys. I needed help badly. in running biopellet and just started a diy algae scrubber. I see some green algae forming. I also have chaeto in my sump. but my display tank wall keep having layers of green algae. after I scrub , it come back 1 or 2 hours again. now my sump tank microbubbles wall also have the green algae. my ammonia 0.nitrate 0 . po4 0.5. is the third week after setting up the tank. I'm using maspect razor 120 w. what's wrong? is my config of photo period too long. mind to share some config? even my sand bed and live rock have sign of green algae .

Your biopellet outlet goes to skimmer or anything? It has to go to skimmer for the skimmer to remove.

[jowenteo]

thanks for replying it flow to my chaeto and flow back to the skimmer.

Try use rowa reduce the phosphate level. Your pellet output should go straight within skimmer intake area. Lighting period ? Is this a new tank with new biopellet?

[jowenteo]

yes its a new tank and new pellet. if my pellet flow to same compartment as skimmer. then the cheato compartment will not have any water flow .

try to use rowa to reduce the phosphate level.

How old is the set up?

[jowenteo]

3 weeks. but is 0.5 ppm for po4 consider high ?

[surreal1228]

0.5 is high for sps.

3 weeks is too short.

Dose bacteria will help

[jxlex]

Give it a bit of time, dose bacteria, allow for biopellet to set in, get some cleaning crews like snails, narcissus and turbo maybe some brittle stars, abalone, etc to feed of the algae...

Run a phosphate reactor over time should settle down if you also watch ur feeding

thanks guys for the advice. I have got myself phosban 150 and rowa phos. now my oh drop from 8.3 to 7.9. my po4 has drop to 0.04 . . how can I raise my ph?

[jxlex]

PH buffer?

[jowenteo]

manage to find out what causes the algae boom. my MP 10 flow was set to the lowest. after I set it to half bar, algae gone. I got the buffer but it was 8.3 then it drop to 8.0 to 8.1 again. try a few times still same

Interesting... Didnt know flow had such an impact on algae...

[dachkie]

does biopellet outlet not flowing to the skimmer have any effect on nuisance algae?

[jxlex]

IMO the impact shouldn't be great, agreed not as effecient as pointed to the skimmer but overtime he shld have limited impact

[dachkie]

just read that if output of reactor not pointed to skimmer , the effulent will feed algae breakout in the main display, could explain y i have 0 no3 and po4 but still getting gha outbreak, but my skimmer is gravity feed and the reactor cant fit into the overflow, so now try to plump the reactor output into the refugium and see what happens, feed the algae in the refugium 1st

[jowenteo]

that's my setup. my reactor outflow to the cheato compartment then it will flow to the inlet of the skimmer pump.

mine was from regugium back to main tank, anyways today i went to buy a skimmer feed pump and redo my setup, now the bp reactor outlet is next to the feed pump

Interesting must really go do some research as my reactor output directly point to return pump and so far no algae issues yet *touch wood* i must have done smthg right somewhere...

Think PO4 level is not affected by adjusting flow per see. Something in the tank is introducing PO4 into the bulk water. Most common source is food. Other source of PO4 is from contaminated rocks and sand.

Its still in the cycling phase, more algae, diatoms, cynobacteria, hair algaes will come, be patience dont add more live stocks, dose bacteria will help. Now its 3 weeks, give the tank 3 months to stabilize. Focus on siphoning at detritus on rocks or bottom of tank.
