Volcanic rock???
I'm not a geologist and don't remember much about what I was taught at
school on the topic but my hubby tells me that over in the far back corner of our farm is an area that a geologist told him had been a volcano. There is rock there that looks very much like some live rock, very porous and open but dark coloured. I need way more rock in my tank but am happy to add dead rock and wait. How can I find out if I could use this stuff? I know there have never been chemicals of any sort used over there and the only possibility of anything like that contaminating it would have been if cattle were dipped for ticks in the yards about a kilometre away and went straight there, which they don't, still dripping (not really possible in our dry climate).

Does the Ca get released into the tank?
I'm the one with the Ca reading of 600 while using NO additives. Not that I imagine that will last once I get more corals.

Hi Miskairal: We have on part of town here in Ks that the city water comes
from a lake that must have a high calcium concentration. People there never add Calcium to there tanks it comes with water changes. maybe that is why your calcium is so high. lucky you.

The real issue here, although I'm not that concerned, is the leaching of heavy metals

The calcium does disolve some, mainly from things digging
in it. Criters can't dig in lava rock. There are some creatrus that take sulfur from the water and produce sulfuric acid, and slowly etch into the calcium rock. Some createrus chew their way into the rock. This is natural, and good. Lava rock does not offer this. Denitrification seems to take place better in calcium base rock and sand, than silica based rock and sand. I can't say for sure what the difference is, but it just seems to be be better, maybe it's the buffering ability. Maybe it's available minerals. I don't know, it just seems better to me.

Afraid that's not the case. I use RO water and the Ca is 0 in that. It
reaches 600 as soon as I add the coralife salt, before it goes in the tank. I've tried other brands of salt but they have phosphates present and the coralife doesn't.

That's what I've always heard also, heavy metals in

Well I might have thought so if the RO water wasn't testing 0 and a
petshop didn't get the same result. One day I will get round to testing the tap water (straight from the creek). By the time I test all my tanks (FW as well) I get sick of testing. My nearest marine pet shops are all 2 1/2 hour's drive away in 3 different directions :( I've tested and tested. There is meant to be a colour change from pink to blue. Mine only changes to dark purple at 600 really. I can get to higher if I try to go for the exact shade of blue and that is in front of a window with good light. At 580 the sample is still bright pink. One thing though. I have some sort of algae or seaweed thing gowing well. Not overtaking but it's looking quite good. It's bright green and sort of cactus shaped, like a zygocactus but it is hard. I'm wondering if it would need Ca to thrive and maybe that is why it is thriving. The tang doesn't touch it as far as I can tell. Visitors love it and think it is planned - I don't enlighten them :) Boomer wrote: Is it possible it is a test error or test kit issue ? |

Under ideal conditions, it can grow quite fast, but it's
very easy to remove in the aquarium. In the ocean, it actually can contribute quite a bit to the sand/substrate.

Exactly Wayne. Don't worry fishnut, the thought has crossed my mind but
it would have to be something extra special to attract customers from the coast where the bulk of the population is.
