Domolite lime and other lost arts...

[powerreef]

Hey steve I not tring to say that the use af a Dolomite bed will cause all life as you know it in your tank to die, I'm just saying is that thier are a lot of untested results of such a substraight, and if we concider the larger ammount of money we pay for corals, gadjets and so on why cheap out here. I'll try to answer some of your questions.

my tank was up and running for about 3 years using this stlye and o combination using dolomite. This said we did not any real corals to talk of back then it was basically white sand coral skelitons and the nastest sea cr\itter we could get.

Can you post some of the links to thease studies please, I haven't been able to find anything on this yet and I would liek to read it.

I will have to search them out , but i will get them to you tommorrow.heres one

ihad discussed the effect mag has on cal in the tank, and you made a general statement that it was good, and indeed it is but at normal levels, what would it be if the mag was increased to to 10 times its natural level.magnesium has a big impact on the rate of precipitation of calcium carbonate. so would that concintration all most reduce calcium precipition to nil or just slightly, would this give us calcium super saturated SW, would this be ok? I dont know do u.

I stated mag ions attach through pairing with other minerals. oopps i meant other ions from other elements.

thier were a couple of things i had stated that you had not retorted on, as in the adverse effects on aquaria inhabitants, that should be something for you to concider. Here is a section out of an article by Craig Bingman, a pretty well known author on aquaria . it reads as follows

Dangers of excessively high or low magnesium

Some aquarists are apparently adding magnesium supplements to their aquariums without performing any testing for magnesium levels. This is a potentially dangerous practice. I can point to no evidence that higher than natural seawater magnesium concentration has a beneficial effect on marine organisms. However, there is evidence that higher than natural seawater concentrations of magnesium can harm marine organisms.
Magnesium salts have been used as a “chemical shucking aid” on oysters and other shellfish for many years (Whyte and Carswell 1983). Magnesium chloride is also used as a relaxant or anaesthetic in pearl oyster culture (Norton et al. 1996). Namba et al. (1995) report persistent relaxation of the adductor muscles of the oyster, Crassostrea gigas, when exposed to solutions of magnesium chloride. The degree of relaxation was dose and time dependent. Higher concentrations of magnesium chloride and longer periods of exposure increased the number of individuals showing persistent relaxation. Significant relaxation was observed in groups of animals exposed to concentrations of magnesium only six times higher than seawater for periods as brief as 30 minutes.

Culloty and Mulcahy (1990) indicate that magnesium salts make an inexpensive anaesthetic agent for Ostrea edulis. In studies of anaesthetic agents for the scallop, Pecten fumatus, Heasman et al. (1995) found that magnesium chloride at 0.31 molar was a good anaesthetic. However, magnesium sulfate at the same dose caused excessive post-anaethesia mortality, a finding that may be interesting and relevant to individuals who use magnesium sulfate heptahydrate (Epsom salts) as a magnesium additive.


anyway it just doesnt seem worth it buddy
