Chaeto Woes

[Trial by Fire]

I cannot get chaeto to grow in my Refugium anymore despite nitrates around 40 and phosphate at 0.1-0.3.

It used to grow like wildfire. I have a Neptune grow light that runs opposite of my display lights. I’ve changed nothing regarding the set up from good growth to no growth.

The only thing that’s changed is my ph runs consistently higher than it was. It now runs from 8.2 to 8.5 daily. My suspicion is the lower co2 is impacting my chaeto growth. This came from talking to a LFS that uses co2 diffusers in his freshwater plant tanks to get them to grow . Am I correct in thinking if I add co2 directly to my tank to drop ph it may allow my chaeto to grow better ?

Trace element depletion. Iron / Manganese most likely.

Even with a tonne of new mixed water being added to the system?

I was going to say this. Try something like ChaetoGro and see if that helps.

No. Flow is the same. And the lights run from 10pm to 10am

When I started with chaeto. Mine died also, but then somehow some of it end up in my tanks overflow and there where it survived, from there i moved a patch to sump/refugium and it's being healthy ever since

Perhaps take advice on trace elements from above comants
