hair algae breakout in fuge and nitrites issue

[Simon68]

My tank is cycling for about 6 weeks now.
Ammonia 0
Nitrites .25
Nitrates 0

In my fuge, I have 15 lbs of live sand, 15 lbs of live rock and a chaeto ball. It's being lit 24/7. I am having a massive hair algae breaout all over the walls of the fuge, the chaeto ball is growing and is a dark green, which I know is good.
There is also what looks like red algae as well along the walls and on some of the rock in the fuge.

For the most part the DT is clear of this, there are some spots of hair algae in the DT, like on a powerhead and some isolated on a rock or two, but mostly it's all in the fuge.

Is this normal, should I shut the lights to the fuge or is it rather the fact that this is in the fuge is the reason it's not in the DT and therefore good?

Also, my nitrites seem stuck at .25 anything to do with that or just wait it out?

Not sure why you cycled a tank with chaeto in the fug.:confused:
But as long as it survived guess it's ok.
How did you cycle the tank...fish,dead shrimp,fish food?
What are you testing with?

Is there a reason not to cycle with Chaeto?
I am cycling with live rock, I have 150 lbs of live rock from Tampa Bay Saltwater. Pretty much cured so never had a big ammonia spike at all. Highest ammonia got was .50 and has been steady at 0 for awhile.
Testing with API.

Well,this is just my theory.
If you cycle a tank with chaeto then a lot of nutrients will be used by it.These same nutrients that become ammonia thus feeding bacteria and triggering/maintaining the cycle.You see,when hobbyist use say a dead shrimp,fish food or a live fish there's a sustained presence of nutrients introduced into the water.Also I'm not sure how chaeto would fare if your ammonia levels got extremely high.Again,this is JMO.:smokin:

Personally I think your tank is cycled and would try to add a few hardy snails and crabs.Maybe a turbo snail and a couple of Blue legged hermits.

Don't worry about the nitrite It may just be testing error, and even if it were 10 ppm, it is not appreciably toxic. I don't recommend even testing for it except for fun. It is never a concern in a reef tank.
