I am pretty sure the calcium level has to be raised, unfortunately I do not have an alkalinity test yet, on the list for this week....my question is will this kill the fish? the calcium level?

Another question, as mentioned I traded my tomato clown for 2 baby (tiny tank bred perc clowns, they are way smaller than the tomato clown, and he wasn't that big), at the moment the 2 clowns are constantly sticking together.
I have read that when they are this young they are all males, and chances are if you have a pair, one will change to female? is this true??
I know the tank is only 20 G, but I plan to have the 65 G I just put a down payment on, up and running in the next couple of months (in which I will have more questions about transferring fish and live rock)

Please let me know, Thanks

Calcium is sort of a "leading indicator" of what is going to happen. This is why it is such a valuable test. It allows you to take action before the problem occurs, preventing all sorts of complications. Calcium itself is not a toxin to the fish, so the actual calcium level of 400ppm will not "kill" the fish. But it does tell you things about your water that could eventually cause problems.

We know that calcium ions are being utilized by the buffer system, in the form of calcium carbonate. Calcium levels above 360 ppm are considered normal. We generally aim for 400ppm - 460ppm as an ideal point. At 400ppm, you have just hit the low end of the spectrum, so adding a Calcium supplement would be correct.

thanks me too !!! Very excited, don't worry I will ask you many, many questions!!! and post pics, But I do want to transfer some of the live rock from my 20 gallon to the new tank once I have it, is there a minimum amount of live rock i should leave in the 20 gallon as a QT?? right now I have about 32-33 Lbs of cured liverock, I plan on have about 70-75 lbs in the 65 gallon.....once again CAN'T WAIT!!!!, I should have the aquarium in about 2 weeks, maybe sooner......

You won't want live rock in the Q tank, because you need to be able to medicate. Believe it or not, you will run that Q tank very similar to a freshwater system, using a biological filter. The reason is simple. You will be changing large amounts of water on a frequent basis in the Q and long term buildup of nitrates is not possible. Also, short term accumulation of organic wastes will be minimal due to the extremely low fish load. Most people even run their Q tanks bare-bottom, so that medication is not absorbed by the calcium based substrate.

well, that's good news for me....not as much liverock to buy as I thought, I already have a freshwater filter, came with the tank when I bought it...
now just shopping around for a protein skimmer, as mentioned I am thinking about giong with the berlin, but have also read some pretty good reviews about the octopus skimmer , and alot less money, have you heard of it? it's a HOB model

You don't want the Octopus Skimmer for a 65 gallon tank. In my opinion, it would be really pushing the limits of this hang on skimmer. I would be very comfortable on a 38 gallon tank, but not a 65. I use a very similar skimmer on my 38 and have used it on a 55 gallon in the past without the quality results I would be looking for.

Remember, the skimmer is the most important purchase! Overbuy!!!!
