help please?

just wondering if anyone knows if its possible to use "cuttings" of macro algae or do i have to take whatever it is that they are already attached to????

What its connected too.. And up your day light hours 16 or 18 to get good growth , most southern species preferr shallow waters fast flow and good mixed spectrum lighting..

eg: a piece of weed i like is attached to "the shore" being a rock headland... im curious as to whether or not i can take it off said headland and "strike" it like u could a plant from your garden??? i have twin t8, currently using an actinic and a 6800k basic tube, i bought a powerglo 18000k tube today but the darn thing didnt work so i got to change that one over. as for water flow im running a 550lph canister and an 1800lph internal filter, i have approx 140 liters of water in my tank so i'm sure there is adequate flow... only weed in my tank at the moment is that green lettuce stuff and some brown weed that is attached to my live rock, i had other stuff in there but it began to foul the tank as im sure my tank isnt yet equipped for so much plant life. the guy at my lfs is going to give me some cuttings off his caulerpa in a couple of weeks which will be good hopefully. thanks again mate, you seem to be the only person of any help to me on here

oh whoops when i first read your reply i thought you said "what's it connected to" not "what its connected to"

Logically, growth occurs at the base of the blades (meristem) in the case of kelps, and the holdfast serves only to anchor the algae. So, I'd say you could try taking just part of the meristem. Though it is usually best to have it attached if you're taking a significant amount since otherwise it is likely to float around in your tank and cause some disruptions.

Algae reproduce via planktonic spores and gametes so taking waters samples could be another a way to cultivate algae as most of them grow pretty fast.

nice! cheers mate ive bumped my light hours up like snapperhead suggested and some of the tiny stumps of algae appear to be growing... we'll see though as the tank is still cycling and im nervously awaiting some form of hideous bloom to take hold
