hi just woundering if you can keep sea grass in a tank or anything else like kelp and stuff like that.

if so what sort of light do they require , newtrents ect.... i got a 1000 ltr tank set up as a fiish only tank (cold marine)

with a couple of sweep, 2 goat fish, 1 spotty, 1 common triplefin, and a fish that looks kinda like a trev but its sumthing else just cant rember the name

any help would be cool

You might be able to keep sea grass with metal halides but most sea weeds need too much light to be practically kept.

sea grass needs to be fully submerged variety, only 2 places in nz it grows fully submerged, i have some growing collected from pools at lowtide that still contained water all year round

this is growing in a 9,500 litre outside pool though

sponges etc and plants from deeper water should be all right as lower light requirements

cool might have to come have a look and bring some goodies with me then thanks for that

Why does the sea grass have to be submerged all the time just woundering

it is better if you can expose it daily then you can just use local grass ie a tidal tank

but in a tank or sump situation mo matter how good the lighting it slowly dies off unless it is a type that is used to full immersion

at the polytech last year we actually did a base-line survey on the submerged sea grass bed at slipper island, looking at exactly what is in the grass (found htat it may be critical for kingfish in the area) and also what detrimental affects anchoring is having.

i think that if you go get some rocks that have a seaweed alrready growin on it it wi;ll make it eaisier to trans in, and you can remove it easier if it starts to degrade

cool

there is a pic of some seaweed in this other thread.

I never did really get a good ID, but have since spotted it growing on rocks at my beach nearby. It did not become a nuisance & is still growing well, and I only have a basic set up... no special lighting. Also, I had weighted down a piece of kelp; the kind that has wide blades, and quite ruffled. It just had one blade and some small roots. It doesn't need weighing down because the roots attached themselves and it has grown!
