chaeto not growing
ITS BEEN TWO MONTHS WITH NO GROWTH in my refug. What gives. nitrates and phosphates at about 0. seems odd to strive for low levels of these two nu-truants if they are needed for growth. i have a compact fluorescent and a led light over my refug. on in the evening

zero nutrients isn't doing your chaeto any favours. both macro algae and coral need at least trace nutrients to thrive.

im thinking a new bulb. heres what i got in the lamp. there are traces of each. 10 MAYBE 20 on the Nitrates and very low phos, Dont remember the last test results. so should i raise the nitrate levels? i strives so hard to get them low according to the advice from this group. was that a mistake? cycle the tank cycle the tank thats all i heard for weeks. nitrates need to be low. they said. its a sign of a cyled tank they said,

Well, if your phosphates are 0, and the chaeto isn't removing that, then that's probably why. Are you running Carbon? Also, I would take the chaeto out of the the bag and let it float around , maybe it isn't getting enough light, I run my red leds for about 12 hours a day on mine. Also, flow might be too low? I've heard some flow helps.

The goal of chaeto is to reduce N and P, not to grow chaeto.

I have noticed issues with my chaeto growth due to how your sump is designed. Yours looks a lot like mine in that the water does not have to flow through the chaeto are. I have noticed with the new style sumps, water works from one end of sump to the other. All water passing through the chaeto. Giving this a little flow as well. Water in your fuge area looks like it may not be moving out of that chamber so no new nutrient rich water is helping with growth.

I'd guess that the alga is limited by light or by the nutrient levels, possibly both. If you want the Chaetomorpha to grow much, then I'd start by increasing the light. I agree that getting rid of the bag might help growth, although some of the Chaetomorpha might get into the display. 13W isn't a lot of light. If that doesn't help, some fertilizer of some sort would help. I'm not sure that it's worth the trouble or cost of adding lights and alga food, though.
