    low PH and Ca?

    Your Ca and Alk appear to be out of balance. For a Ca of 310 you Alk should be more around 2.5 meq/L or so. I would suggest getting your Ca up relative to your alk. You need to target about 420 ppm Ca or so. The problem here is that using either Kalk or your reactor (I'm not very familiar...

    Baking Soda in the Aquarium

    Helpful posts. Sorry I couldn't get to this earlier. I think the homeade 2 part is a very good option. Otherwise just use baking soda or washing soda. The same thing will happen in either case. Same with heating it. These things will affect the intitial change in pH. However, if adding...

    Caulerpa Toxicity in perspective

    Yea, ha ha..!! I'm glad you brought that up. I let him go on that one :-). I can't believe Mike is using urchin studies to back up his arguments. That's a good one...LOL. I'll get to your posts, Nikki and Mike, later today. I largely agree with what you are saying. That is what I meant by...

    Caulerpa Toxicity in perspective

    Ok, here we go! I do not feel that I am making assertions. I feel that I am stating a null hypothesis regarding the use of C. prolifica in a reef tank This is true. All toxicalogical studies have been done with C. taxifolia extracts and have been performed on benthic organisms found in the...

    Caulerpa Toxicity in perspective

    I will read and respond to your posts Mike. First I have to read your references though. And...thanks, that is what I was asking for. I will happily eat my words if I think it appropriate. I like threads like this also. However, I am not really requiring scentific evidence. I don't think I...

    Caulerpa Toxicity in perspective

    Ok, thanks. For who? I'm not sure of your point here? To stop thinking about things and soliciting ideas from others? What do you mean too high? Do you feel I am wasting your time and the time of others? Good, I am glad. The world would be boring if that was the case. However, I think...

    Caulerpa Toxicity in perspective

    I'm not exactly sure what to say to this. It seems that your point is that studies can't help us learn about aquariums. If this is what you are saying I'll disagree wholeheartedly. I would agree that there are not nearly enough applicable studies done. Ok, then to the point. What do you...

    Caulerpa Toxicity in perspective

    I enjoy it. No pain at all...thanks. As for soft corals causing problems for SPS's, that is actually fairly well documented and there have been some studies on it. I have no problem with that. Softies and LPS naturally compete with SPS, so it stands to reason that they will have...

    Caulerpa Toxicity in perspective

    Well, this is the danger. I deal with this all the time in my industry. Ideas are mis-interpreted, based on a specific case, and then expanded to other cases that are not truly relevant. Alternatively, they may be taken out of context and fiction tends to then become reality over time. I...

    Caulerpa Toxicity in perspective

    Why so? Can you point to a single study that validates this statement? I'm not talking about some anecotal evidence, but a quantitative study that supports this? I would be interested to see it. I couldn't find any such. Reason being is that I did find may individual reports of people...

    P.S. All that being said, as was pointed out by several. There are likely better algeas to use....Collin

    Caulerpa Toxicity in perspective

    I have been taking an effort to better understand Caulerpa toxicity. It seems that Caulerpa was widely used and considered AOK to the aquarium industry until some point where at a Boston Reef Meeting, somebody announced the finding that Caulerpa was toxic. Since then there seems to have been a...

    Strontium is too high..

    Ed, here is a strontium link: http://www.advancedaquarist.com/issues/nov2003/chem.htm If your strontium is indeed 40, then this is about the point at which a few animals start to exhibit toxicity. I would suggest validating this number with another test kit. If it is indeed that high, then...

    DIY Refugiums, any help?

    I read the article you posed. I think the following quote sums it up best. "This lack of understanding may be leading aquarists to fear things that are not a problem, and to miss things that are." The whole article basically defines the DOM's, POM's etc. and then goes on to say they are...

    What about Mg?

    High Mg won't hurt (well unless it isn't like 5000 ppm or somesuch). You should try to target natural levels but a range above or slightly below isn't a big deal. Water changes will help here if you use a salt that has the correct levels. I wouldn't worry about it too much. It will...

    DIY Refugiums, any help?

    I think this is accurate. I have softies, and lps in my tank. The only sps (and this is sometimes debated) is a horn coral (hydnophora). All are doing very well. Regarding the Culerpa though, I have never really looked into it from a technical perspective. However, if it is putting out...

    DIY Refugiums, any help?

    aquariumdebacle, I am not trying to justify anything. Culerpa may very well not be the best algea. It may even be the worst. I only know I have not had problems with it. Another thing I know is that I have a friend who has an aquarium maintenance business. He has over 50 setups in the...

    DIY Refugiums, any help?

    Ok well, to be honest. The bowl idea was one I had after I set mine up. I just have mud in the bottom of my fuge with algea in it. However, there is absolutely no reason the bowls won't work. When I next rotate out my mud, I will put it into bowls. If you do it, you will be the first to try...

    Ca/Alk imbalance vs. pH....

    No, I'm sorry. I did not mean to give that impression. I'm not sure why you think I meant that, but I must have mis-spoke myself somehow. pH is definitely affected by ambient CO2 levels. It is strictly a thermodynamic fact. If respiration is such that CO2 levels rise substantially, then pH...

    Ca/Alk imbalance vs. pH....

    Cougra, it is a little different in a saltwater tank because of the large amounts of carbonate and bicarbonate which depends upon the CO2 in the air via carbonic acid. If you add too much of either carbonate or bi-carbonate into the tank, CO2 will either be drawn in or released to establish...
