Stupid question on chaeto

There are no stupid questions when it comes to marine tanks.
Chaetomorpha is a beneficial macro algae that is used to balance a marine system.
Chaeto is also considered to be a safe algae as it's not invasive or can't go asexual like calupera (which can crash a tank if it does) IMO I wouldn't even consider having any marine tank without it. Chaeto consumes nutrients which will starve other unwanted algaes and is one of the very best algaes for nutrient export and plankton production in refugiums. Chaeto is a long, thin algae that grows in dense clumps and fairly easy to grow.

i recently got some cheato, but only like.. a handful.
about how long would it generally take to - say for example - double?
i have it in a sort of netted basket in my DT right now because i dont have a sump yet... so im just wondering what sort of growth speed i should be looking at (under PCs)
thanks :-D

Grows fairly fast, likes to have lots of water flowing thru it and decent, but not super bright light. 6500k is ideal for chaeto.
I started off with a small $10 clump that was the size of a baseball, now I harvest about 3-4 gallons each month.

I started with a softball size clump in my 100 gallon sump/refugium on my 180. I typically remove 20+ Lbs of it every couple of months....
Given proper lighting and strong flow it grows faster than a weed.
Fwiw, I have mine under a 250 HWI 10000k bulb.

Absolutely will grow without mh lighting. Just decent strong light is sufficient. Even a grow-lamp over the sump will work.
