No, the wavelength doesn't shift, I don't think. They do lose their brightness over time, but it's usually something like down to 1/2 after 100,000 hours. Shouldn't do any damage, those will be using UV just barely outside of the visible spectrum...Maybe if you blasted it straight into their eyes, but the same goes for visible light.

Might be better going for a UV CCFL than a bunch of LEDs, more light and better spread.

Damn, I just really like the oystershell look. I do remember a thread about the phosphate thing and I think someone ran a test, ill see if I can find it - if rc isnt overloaded - man they are useless!

Its a free service! If you are frustrated by the performance donate some money, become a RC sponsor and all of those problems will dissapear.

If it didnt use advertising I would consider it free. Using the site gains them money from the ads - the site probably wouldnt be there otherwise.

I think that they'd be rolling in money, any site that constantly has around 1500+ people online must be doing well -especially given the money they spend.

Definately enough to pay for a search that functions properly.

Cheers layton, I knew you could search with google, but I didn't know how.

I paid them my fee, then got banned not long afterwards & they kept the change. Not hugely impressed.

So then I used the crippled search was a bit of a hassle, but lately its been working every time.

BTW Layton when I was there I found this guy http://reefcentral.com/forums/member.ph ... did=697472

Friend of yours? :D

Oh and Layton thanks for that google search thing, I didn't know about that either. :hail:

Does that include internal things like closed loops? I was thinking just return, but I spose internal would count aswell.

I just had a rough geuss at mine and it looks to be about 20x due to the return, depends on how high my return pipe has to be.

Is it the more flow the merrier?

So wasp, how did you get banned!!!

Tell me and we'll both know.

I discussed zeovit, but in much more polite terms than has happened on this board. They purged heaps of zeovit users and my number must have come up.

I asked others to search my last few posts and see what my crime was, but noone could find anything.

But who cares. Just set up a new user name. No worries :lol: :lol:

BTW I've got 80 x flow :D

interesting topic.

but to get back on track, i have been experimenting with foam cement.

process.

get some foam rubber, or sponge, and "wash" it in a cement water mix,

shape it to your desired form. when set, take it to the beach for a while.

this will cure the cement, and rot out the sponge/foam, leaving a very porous rock structure.

good luck.

Ohh ok so turnover is what I was thinking about. 20x turnover for mine nearly. Would this make the surface visably rough? I rekon that looks cool.

Hey neople, I have found a good thread on RC with the oystercrete and it is very porous apparently. Water will go through it, if you make a cup out of it and fill it,- the water will drain.

Also if you have foam rubber, you can make a mould of a coral skeleton, and then fill it with mix and make corals into the rock. Looks real cool.

2 1/2 months ago I bought 3 x 40 kg bags of portland cement from Stevensons, they were $13.11 + GST per bag.

That would be normal portland cement which is cheap. The white stuff is expensive.

Interesting idea on that site regarding adding noodles etc. I take it they mean pasta noodles. These would create cavites and during the water curing process they would disolve creating the small cavities. Will try it and see.

So has anyone started making any rocks yet? I still have yet to start. How much would 80L of sand be? (for the mould). I need some sort of container to make it all in.

I'm definately gonna cure my homemade rocks in the sea with my base rock, hopefully will make the curing process go real fast. It'll be there for a few months while I go back home.

Also found out I might be able to keep more than one octopus, and that possibly I can get them from someone working at Seahorse World in Picton.

Hopefully they'll get on ok, otherwise the winner will kill the loser and eat it. :o They try to get their arms into each others mantle and grab onto the gill structure inside the opponents head to suffocate them. Pretty savage!

I have keep octopuses before you shouldn't keep multiple octopuses together because two senarios will occur either:

They will both be males or females, and they will fight and die which is not very hummane to pervoke this death although it occurs in the wild.

Or secondly be male and female and they will mate and both will die eventually. So to sum it up just keep one.

Also you should be worried about the water quality as octo need pristine and well oxygenated water for respiration due to thier biology moreso than other marine fish.

Octopuses aren't easy animals to keep check out www.tonmo.com or read up on them otherwise you might end up disappointed. Would be very skeptical about the effect of homemade rock on WQ unless it was fully cured.
