for future consideration-----while your alk is falling
what is your pH----did you or are you dosing with a buffer---alot contain boron which can raise your alk levels very high.

Nice thread.
Need some help from expert advise tank size 120 gal I'm currently dosing Randy's receipe 1 for my SPS tank Kh 50ml - 2 hrs once start from 12am (eg. 12am, 2am, 4am ...) Ca 90ml - 2 hrs once start from 1am (Eg. 1am, 3am, 5am....) each dosing amount will last 55mins and 5 mins rest before the next one started (about 7drops or so every 20sec estimated) Total dosing amount at night Kh 350ml ca700ml Mg 300ml every 3 days once at 7pm Every night measure at 9.00pm Ca 400-420, kh 8.0-8.4 Mg 1280-1320 i struggled for almost 2 weeks before i manage to get this result due to ionic imbalance Recently, PH drop significantly after switching all the dosing after lights off. Now (8.0-8.3) before was (8.2-8.5). I'm contemplating to slowly adjust back to 8.1-8.4 by delaying the dosing starting from 4am instead of 12am. I'm very keen to know 1) Is there any way to measure the highly concentrated dosing solution using our test kit. 2) I don't know why but i need to dose a lot more ca solution than kh - i'm worry. Is it because CA precipitate causing more solution required when dosing? 3) what is the safe dosing amount/qty quantity within an hour ? Hope someone can share his experience. Thanks |

Joyt,
To Reef Central Why are you dosing so frequently? It appears you are dosing every two hours? It sure sounds like you are dosing more than is necessary for a 120g tank, but when I was dosing, it was with B-Ionic. |

For measuring the concentration of the solutions you could do a 50 or 100 fold dilution (or whatever dilution you'd like to) and measure the concentrations. Make sure you're as accurate as possible in diluting, otherwise your calculated values will be off.
A possible and perhaps likely reason that the you need to use more of the calcium solution is that the actual calcium concentration is lower than calculated value due to hydration of the calcium chloride. Calcium chloride picks up water very, very easily (used as a dehydrant in some applications because it sucks up water so easily). This means that you may have mixed up a more dilute solution than you intended because much of the mass/volume of the salt was actually just water. That does seem like a lot of dosing, so I'd be suspicious that a lot of what you're adding is precipitating abiotically. How exactly are you adding these solutions? cj

Potentially, I have made a mistake when mixing the solution. Anyway, will try your 100 fold dilution method since the suppose solution should be Ca - 47000ppm. many thanks |

Make sure you measure first---it should be at 1300. I use Kent Tech-m

its really important to know your calcium, magnesium , alk and pH levels---can you post these?

Joyt,
why are you dosing so much so fast? 90ml every 2 hrs? thats too much. I run my dosers 24/7 I dose 11 ml per hour of each. 11ml x 24 hrs = 264 ml per day Its better to dose slowly all day long then large amount quickly. I arrived at that value easily. I did a search on RC to find what most people were dosing for my tank size. I started with that figure (9ml per hr I think it was) and fine tuned it from there. I recently went to dosing Kalk using a reactor to lower my 2 part usage and to raise my pH. Its working beautifully. Between running a hose to the outside for the skimmer and running Kalk my pH has gone from 77 to 8.1 Last edited by Zedar; 10/29/2007 at 08:25 AM. |

Discover that my Ca solution was too diluted after using cj measuring method. dreaming while mixing the solution . Now, everything is back to normal. |

Re: Let's talk about Alkalinity, Calcium and Magnesium in an SPS Tank
May I know what is the difference you observed from SPS when magnesium level is at 1450-1500 ppm compared with that of 1300 ppm?

I felt I had less problems keeping alk and ca stable. Also I personally felt I had slightly better coloration, YMMV on that part.
