Kalk cause Imbalance between NO3 and PO4
I am at a loss here. I have a 29 gallon aquarium with
2 small matron clowns 1 small pajama cardinal 1 small twin spot blenny I am dosing 1.5 tsp of kalk per gallon I am currently doing a 15% water change weekly I am using distilled water. I have tested for TDS and I am getting 0 including 0 nitrates. I feeding around a 1/4 cube of mysis 5 times a week. I just started dosing Nopox My nitrates are around 30 My phosphates are around .05 Could the kalkawaser be causing this imbalance? I have heard that it will break down the phosphates and increase nitrates. I know that we are all striving for the 16:1 ratio with nitrate to phosphate. I am way off. Pleas help me out |

There's a theory that Kalk can precipitate phosphate (as calcium phosphate), but it's never been shown to happen in a tank. Those nitrate and phosphate levels are consistently with a lot of other tanks, so I don't see any reason to assume that there's a problem.
I'm not sure where the 16:1 ratio originated, unless that's the Redfield Ratio, which doesn't much apply in our tanks. 30 ppm of nitrate is fine for a wide range of animals, so I'd likely just ignore it, but reducing the feeding might be appropriate if you'd like to lower the level. Other approaches might help, too. Are any animals having problems? If so, I'd try some water changes in the short term.

As I understand, you could try adding vinegar to the kalk and the bacteria that grows will consume you nitrates/phosphates at a 16-1 ratio

There's no guarantee that vinegar will consume the nutrients in that ratio. The actual ratio might be close, but the denitrification process can consume nitrate without any net phosphate consumption.

Thanks for all your help.
I am dosing Nopox at the moment. How much vinager per gallon? My frogspawn is not happy. It hasn’t come out in a couple of weeks. It still has color and it isn’t dead but it definitely not happy |

I think Mr. Bertoni had a chart showing the ramping ml per gallon?

NOPOx is a combination of ethanol and vinegar, basically, so you might want to increase the dose of that product. There's also a DIY recipe available. As far as vinegar goes, it'll work the same way as the NOPOx, although it might cause some side effects. Every tank seems to respond differently to carbon dosing.
This article covers vinegar dosing: http://reefkeeping.com/joomla/index....arine-aquarium The recommendations are very conservative, though.

Okay thanks for the article. I will read it.
What about a chaeto reactor? |

Sometimes Chaetomorpha helps with nutrient levels. It's reasonable to try adding one, but the lighting might get expensive over time. They will provide a lot of live food to the tank if you stock it with some small animals, e.g., amphipods, copepods, mysid shrimp, or appropriate isopods. If the tank has some good quality live rock, stocking might be optional.

What is a good starting point for vinager per gallon in my ATO with Kalk for a 29 gallon. Probably around 20 gallons of water after displacement fro sand and rocks |

Diluting the vinegar will cause it to decay before getting into the tank unless you add a preservative like Kalk to it. We'd need to know the evaporation rate to help much, and also the current NOPOx dose probably should be subtracted from the total.

Mix the kalk with the vinegar. Use approx. 3.75 times your nopox dose to start
Cheers!

I am taking it slow.
A lot of people suggest dosing half of what your supposed to. I am playing it a little more safe and I intend on increasing weekly |

Well if nopox is anything like vinegar, it will take some time to see results. I had to wait until the bacteria that ate the carbon got established and consumed nitrates/phosphates. And it seems that with the very little nopox you are dosing, you are not going to see a huge instant change. Patience.
Cheers! Mark

Yeah I figured.
Based on bertoni’s vinager dosing chart. I should only start with .8 ml a day for the first three days. Should I start here or should I do more since I have been dosing Nopox? |

I presume that you have a good skimmer and good circulation (especially at the surface)?

I have a tunze 9001 which works pretty well and an mp10 and a AC70 that puts out around 350 GPH on the surface
So I should put 15 ml of vinager to star out in a gallon of ATO since I use 1/3 a gallon a day Last edited by Indiana Reefin; 01/20/2018 at 02:13 PM. |
