i cant get rid of algae.

Is the alk 3.6 meq or dKH. If dKH you need to get it between 8 and 12, if meq you are in the range for dKH. Buy granulated ferric oxide and run it in your sump or some compartment that you can force the flow through the GFO. Lights out for 6 to 7 days and cover the tank so no ambient light gets in.

 

wow! yeah gfo, and no lights for a while.. wow!

 

Definately looks like Dino's to me. I had them in my Pico. The bubbles will pull up the strings like flying a balloon. I did 2 partial water changes a week, knocked them off with a brush, and harvested them out of the water with a net. I also stirred up the sand in small sections to release nitrogen bubbles. They grow Extremely fast. I just kept doing this, and within a few weeks it ran it's course. Good Luck. BTW this happened after I boiled my rocks, so I dont think that is a fix.

 

it changes from 71 at night to 75 when the lights are on.
so bring up alk. and check phosphate levels?
and no i havent added anything. could it be my filtration? i forgot that the 180gph pump broke so i put the stock one back in, im not sure the gph on the stock pump.

 

i feed my fish once a day its called bio blend.come to think of it, this is the only tank out of 4 that im feeding bioblend....hhmm?
tested just a few min ago.
KH=240
N02=0
N03=80
ph=8.3
Ca=450
no more alk tests gotta buy more

 

if i do run with no lights for days what do i do with the coral?

 

I wouldnt worry about corals if no lights for a few days.. I would manually remove that algae, 25%+ water change (high nitrates), run phosphate remover & carbon, add powerhead, feed every other day. and look into putting some macro algae into DT down the road.. will help sucks up nitrates.

 

A macro algae of one sort is always beneficial in a DT. If it starts growing rampant, it's a good thing- it means it's absorbing the phosphates and nitrates that would otherwise be feeding those nuissance algaes. Only difference is that macro algaes can be cropped and maintained much easier.
I personally of some halimeda macro in my tank Which doesn't look to bad and I remove 1/3 of it every water change and keeps the cyano/hair algae problem that I used to have in check.

 

Maybe a helpful link to solve your problem: Reefs.org: Where Reefkeeping Begins on the Internet - Dinoflagellates, or was that "Boogers with Bubbles"?
Definitely turn the lights off...
Best of luck to you!!

 

pretty high nitrates! I put put some chaeto in my 12g nano in the back corner
