danmhippo: Are you using any additives besides Calcium? Yes, I used Turbo Calcium and Super Buffer before switching to kalkwasser. I also add Strontium/Molybdenum, Magnesium and Iodine. Do you have test kits telling you if you under dose, or over dose the additives? Not yet (some tests are...

EmilyB: Oxegenation? Please elaborate. I never considered this. Would fish that hide, stay lower, or move less be more effected? Can this be measured or observed? Does it fluctuate enough? Is it an issue in a 120 with 600gph return, dual corner overflows, and EV90 skimmer? Does this...

davidmohr I don't really know if coral or fish stand up amonia/nitrite/nitrate poisoning better. However this is irrelevant, none of these substances are present in enough quantity to affect either coral or fish adversely.

naesco: Your fish are dying because you are not giving them a chance to live. This is not a flame it is a fact which unfortuneatley most new reefers experience so don't feel badly. Others can cover the water perameters and stuff I will help you with the livestock if you want me to. Here's the...

nhan: I realize the 37 fish in a 120 would be pushing it - if they all lived. I don't have that problem. The tank has been at best moderately stocked. And, as you said, agression would result in fights and injury, rather than healthy fish happy with there tankmates simply vanishing...

Any new advice or ideas would be much appreciated. Since starting a 120-gallon reef tank 4 months ago, I have had very bad 'luck' with fish. I have added 37 fish, of which only 18 still live. These are mostly small fish added slowly - the tank never could be called overstocked. Ironically...

Discuss the questionable items with the LFS. If they are trying to sell them to people with no idea what they are buying, I wouldn't even buy 'easy' animals from them - I'd run like hell. If the LFS has different opinions about the difficulty in keeping them (and is generally right about other...

Great articles! but my biggest question wasn't addressed. Our aquariums contain large quantities of Na+ and Cl- ions. Does the ratio between these ions matter? What happens if I have a lot more Cl- ions than seawater, and fewer Na+ ions? Do we not test for Cl- and Na+ becuase they aren't...

This comes up a lot, but I wanted to a thread dedicated to this, as I have never seen a good answer. A lot of people suggest the importance of adding Calcium Chloride and buffer in the correct ratios. If I add Calcium Chloride without Sodium Carbonate, the Caclium will get used as Calcium...

Not practical, danger asside - either you need a constantly replace the liquid nitrogen, or re-compress/chill it (much harder than using freon or other airconditioning fluids - as a chiller does). I really like the frozen milk jug idea! Much more cheap, efficient, quiet, and probabably more...

LOL <BLOCKQUOTE><font size="1" face="Verdana, Helvetica, sans-serif">quote Kalwassar is german for 'Chalk Water' and is Calcium Hydroxide (CaHO-). It was the first popular method to replace depleted calcium. It has to be dripped slowly, and must sit around after being mixed - so many think...

Well, I am not an 'expert', but I have heard of Mandarins and other small fish getting eaten by anemones, and anemones will sting corals they touch. Personally, I don't plan on ever keeping an anemone - they are a risk to tankmates, they are hard to keep, they move, and they don't look nearly...

There is a fine line between a foolish hobbiest buying something they don't know about and can't keep, and a researcher experimenting with a new method to further our hobby. There is also a fine line between an ignorant hobbiest buying something from an educated LFS, and an educated hobbiest...
