    Hello again dear friends. I think you know the deal by now, I will post a question and will give karma to all who play. All senior reefers will give karma to the first person who not only answers the question but is most complete. Each week’s question is posted with years of experience to play. Tonight's question is of medium difficulty so I will increase the years of experience to 3 – if you have 3 years experience or less you are eligible to answer the question.

    I am glad to say, I leave for vacation early tomorrow morning but I will be logged online tomorrow afternoon to see how the thread develops and respond. Once again, this is posted in General since its all in the name of fun as well as education. Enjoy....

    Please see the picture below (credit’s to be given tomorrow). Please tell us what is on this heater and what caused it. The heater has been in use in a reef tank and working well all the while, about 12 months or so.

    Film algae. Too low of flow, exposure to lights in the 5000k to 6000k lights, and not properly controlling your nitrates. Boom!

    this could be multiple things.

    im gonna go with diatoms. the user probobaly just added a new filter or power head. will subside when all silicates are used up.

    i think you were frying chicken in a skillet and accidentally tossed your heater in. Therefore my answer is grease.

    It's burned calcium and magnesium carbonate built up on the heater while dripping kalk.

    Kinda looks like it's baked on due to the heat. Maybe hardened film algae or diatoms?

    OK, 4am Saturday morning and heading to the airport....but first I'll post a quick answer and others can elaborate for me since I need to move my butt.

    Keep in mind that a heater in use will not grow algae.

    Calcium Carbonate. Precipitation of calcium carbonate.

    Being the educated forum that we are – we all know that our systems are generally supersaturated with calcium carbonate which normally precipitates very slowly mostly due to magnesium ions keeping it in check. From time to time we will read a post along the lines “It’s snowing in my tank” more than likely this is the calcium coming out of saturation because the supersaturation became to high and the pressure too great for the magnesium ions to handle. Various reasons being the culprit, elevated calcium, alkalinity, PH and elevated temperature.

    Randy Holmes has explained that a tank with a PH of 8.5 has twice the supersaturation of a tank with alkalinity of 8.2 and the same from 8.2 to 7.9.

    As water is heated the equilibrium between bicarbonate and carbonate swings towards carbonate. Thus, heaters (and pumps btw) raise the temperature and the calcium carbonate to come out of saturation and settles directly onto the heater – it also helps that the heater is lacking algae and provides a generally clean surface for the build up of carbonate.

    I used Randy Holmes picture from his article on Calcium, no time to research links at the moment....wife is calling me to heft luggage from upstairs. Thanks for playing !!

    Oh yeah...I forgot the extra credit question for all you eager beavers....what comes next:
    1 11 21 1211 111221 no internet searches....you know it or you don't so no cheating !

    Don't know the name of the sequence but you essentially write or "talk" out the order of the previous group of like numbers next to each other - with numbers.

    So for the last order of numbers you provided (111221) it would be: "Three Ones's two two's one one" or 312211 - Rinse and repeat.

    So I posted my previous response before a bbq and began thinking more about it while there. Specifically, exactly how large the numerical sequence might grow once you reach higher steps into the pattern. The most I've written by hand might have been 10 or so steps when I first learned about the pattern in college, so now that I'm back from the bbq and a few deep, as usual, my curiosity got the best of me.

    I wrote a quick .NET console app whose purpose is to output each step of the pattern from 1 to n into a text file. Up to 20 steps into the pattern generates quickly. 30 and above and you see a significant performance hit in generating the resultant string. I went to 50 steps and it took up to 8 minutes to generate. Granted, the app wasn't written to be super efficient and I'm sure I could optimize it quite a bit. It's less than 100 lines of code currently and could easily be brought down to less than 40, I'm sure.

    To give a quick example of the growth, here's the output of the following steps after that of my first response generated from my program:

    10 : 13211311123113112211

    11 : 11131221133112132113212221

    12 : 3113112221232112111312211312113211

    ........

    16 : 132113213221133112132113311211131221121321131211132221123113112221131112311332111213211322211312113211

    17 : 11131221131211132221232112111312212321123113112221121113122113111231133221121321132132211331121321231231121113122113322113111221131221

    18 : 31131122211311123113321112131221123113112211121312211213211321322112311311222113311213212322211211131221131211132221232112111312111213111213211231131122212322211331222113112211

    etc..etc...

    Step 50 has almost 900,000 individual numerals in the string, clocking in at 894,810 exactly. It takes up over 250 Microsoft Word pages alone at 11 pt font.

    I've attached the resultant text file of the pattern if anyone's interested to see how it grows from 1-50. Pretty interesting stuff.

    edit: No I haven't as the file extremely exceeds the max limit for attachments on the forum.

    Anyway, just some extra extra credit for you Crimson. Cool trivia question btw. It took a second for it to all come back to me. I also have the application for anyone who's interested in seeing how high they're willing to take the pattern. 50 steps was the most I was willing to wait.

    Oh and I finally just learned the actual name of the pattern from wikipedia is called the "Pea Pattern". ;)

    Cheer's - Happy and safe 4'th of July everyone@!

    Oh well, I was really hoping to entice our more experienced reefers into a discussion on the relationship of cal, ma, alk, ph, salinity and temp.

    Anyone with a question idea for me for next week please send it to me.

    The Pea Pattern is always fun – since this is always a fun forum I thought I’d tack that on...

    I'm gunna justy make a guess. If it was on other things in the tank i'd suggest diatoms or algae.
    If only on the heater i'd think due to the heater being better conditions that the surrounding system. So, with tthat scenario I'd guess it may not be algae. I don't know, but I want to know the answer now. :)

    Without cheating. I learned this in MCSE class.
    There is 3 ones 2 twos and 1 one. so the next number is 312211
    next would be 13112221 followed by 1113213211 then 31131211131221 etc.

    WOW this post is old!

    I seen that before, that's my guess also, baked on calcium, I scraped that stuff many times off my heater.

    What is karma?
    Well Wrassman said it best -

    "Karma is just a fun way of expressing yourself on the board. If you like someone's post, or if it has been helpful to you (or others) in some way, then you should give positive karma. (By clicking on the karma button on their post profile - )

    On the other hand, if someone is rude and nasty to you or someone else, you can take away their karma (that won't happen here :) )"

    It's as simple as that. Have fun with it !!

    Giving karma is a member's only feature.

    No flame wars over karma please! Remember it's just for fun.
