serious green water "needs fix"

[Aquarium_Medics]

Get a UV sterilizer. It will remove the suspended algae.

If you have a sump and room in it try building an algae scrubber easy to do and the results are fantastic.I have one running now for 2 weeks and i can,t beleive the effect it has had on my tank green hair disappearing and some red slime is now all gone.There is a thread started in the reef section have a look at it.
Cheers Larry.

unfortunately uv isnt and option right now. and that scrubber basically does what my chaeto does if im correct? from what i have read tho, both great options. my cheato hasnt been getting as much flow to my system for the last couple weeks. could that maybe be the cause of the suspended algae bloom all of a sudden? will the chaeto out compete the bloom? i pulled the chaeto from my tank because i was gonna black it out. should i forget the black out, put the chaeto directly in my dt, and continue with water changes? my kids are complaining they cant see the fish anymore, last thing i wanna do is cover it up so we cant see anything at all.

It very well could be, you're very right the Chaeto in very simple terms is a fast growing plant that out competes the algae for nutrients meaning that the algae has nothing to "feed" or grow off of.

You could always increase the flow, i'm assuming the chaeto is in the fuge? More flow means more water movement but this would be a SUPER slow process.

The kids are complaining I would suggest you do the WC/BO/WC and you wouldn't be able to see the tank for 2-4 days BUT you can't see the tank right now anways

yes the chaeto was in my sump/fuge (for about 8 months with no issues) untill i moved it to a slower flowing fuge a couple weeks back (then did my long overdue w/c last week). then BAM green water (and i mean GREEN, i cant see the fish till they r at the glass). the only fish bothered seems to b my little scooter blenny. i read about low oxygen during the algae bloom. is blasting air through a power head bad for the fish at all? should i just have an air stone, or is just the skimmer sufficient? i guess ill just prep for wc/bo/wc and put the chaeto back in a higher flow area when im done. other than a uv sterilizer i dont see any other fix. pretty sure its not gonna fix itself anytime soon... thanx

Instead of blasting air through your Powerhead you could always point through the surface for some agitation which would give you some extra O2 action!!

The low oxygen wouldn't be direct cause from the algae. I'm no biologist but it makes sense!

I sounds like your problems started when you moved the chaeto and did a WC. So why not try to go back to the old ways and If that doesn't work...........(which i'm quite certain it will) I give up!

You can also PM me if you need.

The low oxygen would be direct cause from the algae using it for photosynthesis. I'm no biologist but it makes sense!

it started when i did the water change. puting the chaeto back could work eventually, but ill go for the black out and see if the problem returns. assuming the black out clears the water (which im sure it will).

Its sounds like the skimmer is insufficient if you're having this problem. It might be time for an upgrade. What is your current skimmer and how large is your system? Blasting air bubbles into the tank shouldn't hurt the fish but trapped air bubbles around the tissue of coral could kill them if you have any.

Photosynthesis in plants and algae produces oxygen. Respiration in animals and fish uses it up and produces carbon dioxide.

reading my post now, that is what I was trying to get out I guess I posted the direct opposite of what was supposed to be implied, but with that being said..

- If the algae doesn't produce enough oxygen in the water during the day it is possible for your oxygen content to deplete during the night. The dying organic matter and algae do use up oxygen at night along with fish. If I remember that correctly, its more relevent for a pond and algae blooms but I would assume there is some relevence to aquarium life. I guess that's where your Skimmer would come in to remove the dead oragnic matter.

from what i got, during the day it makes oxygen and at night it robs the oxygen. with a blackout it will b "night" for 2-4 days (anybody know how long exactly?) this is when i worry about the lack of oxygen. as for the corrals, a couple leathers and some acans i moved to a new home a couple days ago (they didnt look happy (havnt for sometime now) and didnt want them in the blackout?). originally i thought it was one of the leathers dying and mirking up the water.
