Fallen Posted June 21, 2003 Report Share Posted June 21, 2003 Does anyone know what lighting level i need to keep marine plants alive, like the types that you find in rock pool's around the country, i have tried and tried. they must need a crap load cause at one stage i had 4, 3 foot power glo's on my 3 foot tank and that fail and yes i did work up from 2,3 then finally 4 light's, so i am figuring that i wasn't cooking them with too much light and i still haven't got the right lighting level yet :-?, so have given up for the time being and live with fake plants :evil: I have in my tank, heaps rocks, a couple of bivalue type shellfish, a lot of different starfish, chiton's, univalve shellfish, crabs, 2 types of shrimp, barnacles, about 6 different types of sea anemones (which are awesome when they all open up) and i finally managed to get a kina and 2 wandering anemone, on my last hunting trip for shrimp. whooo hooo but nothing is as good as having living seaweed/plants. I could use deeper level plants but i want my tank to look like a rock pool. Quote Link to comment Share on other sites More sharing options...
Caryl Posted June 21, 2003 Report Share Posted June 21, 2003 Our rock pools only have seaweed and sea lettuce. We kept a rockpool tank going for a couple of years but had to give up as it got too hot over the summer months (not that you would have so much trouble in Wgtn ) We only had a single light on it so we could see the fish.

peety Posted June 22, 2003 Report Share Posted June 22, 2003 I have same prob. Still workin on findin a suitable seaweed for home. 250 watt metal halide still isn't hot enough. I'm getting a 400 watter in soon so will have to retry all plants once I get it hooked up. All the critters are fine, but the plants rot out.... If you figure it out let me know.... If you can get hold of caulerpa, that grows at lower levels (hence the fact it is illegal, it grows like a weed in any conditions) peety Quote Link to comment Share on other sites More sharing options...
Pies Posted June 26, 2003 Report Share Posted June 26, 2003 OK first thing to remember is that they are not plants, but algae. There are very few true marine plants (seagrass may well be the only one, can't remeber but have read this). Peety, not sure all that power is nessessary dude! I have microalgae growing under fluros in a shallow tank, and at depth (600mm) under 250watt Metal halide. Green and red, but Red seems to require only a little, and shaded light. Be careful with marine algae, it can SUCK a lot of calcium out of a tank real fast, it can also go 'sexual' or asexual and dieoff too, which can force the tank into instability.
