Refugium Roids

[OnePuffMan]

I saw the Refugium Roids on the @CopepodsForSale website and would like to hear of anyone's experience. My phosphates are always around 0.1 and never seem to move, but I can never get chaeto to grow in my tank. They don't really die; they just don't get any larger. I have plenty of flow, a GLO light (tried anywhere from 8 to 12 hours), so I am wondering if something like this will help.

I will say that my tank is happy and everything seems happy, so it might not be worth it, but I might be interested to try.

What all do you currently do for it?

Dose iron

Dose iron

I agree.

I just have a wad of chaeto in a soap dish in DT (((no sump))) but it's been alive for 5+ years across a couple of tanks.
I definitely have to pull and chuck hunks more often when I'm dosing iron. (I just use cheap Fergon knock-off from Amazon based on one of Randy's DIY recipes).
*that's just from observation but I'm pretty convinced (for my tank anyway)

There's obviously more possibilities than that but simple/cheap to try.
ICP test would be nice but, in lieu of that...
