    Two part unbalanced issue

    hi everyone, I have notice recently when I added same amount of two parts (dosing pump checked), my alk is descreaing and cal is increasing. Any thought? Week 1 Alk 7.7 ( correct back to 8.5 by dosing 30ml of alk) Cal 460 Week 2 Alk 7.7 Cal 470

    High Alk?

    I just tested my Alk and it came up 12.2 dKH, I normally run it at 8.0 and it stayed there up until the middle of November. I did a water change with red sea salt and I turned my doser to 2ml every other day and that was about two weeks ago but now like I said before 12.2, before the water...

    Odd drop in Alkalinity

    Why am I seeing such a low measure of Alk? I measured it at 5.6 today. The Alk was struggling to stay over 7 the last 2-3 weeks. Last year, I had to watch things or the Alk would jump over 10! I'm running a calcium reactor AND a Kalk reactor so this really made me scratch my head. I've...

    ICP-Analysis Results

    Hello Everyone, What a great forum! I received my test results back from ICP- Analysis Friday. I would like some input from the Forum about the results. Especially look forward to feed back from Randy Holmes- Farley. In readying the Forums over the last few months. I find your input to very...

    Phosphate reagent expired

    I have the Milwaukee Mi412 for low phosphate testing. I have 50+ packets of phosphate reagent that expired on 6/2017. Should I toss it or can I get a few more months out of it? Thanks

    keeping levels stable?

    ok I feel like I'm not sure how to maintain my levels at a stable point. I did a water change on May 26 and checked my alk and it read at 9.5 dKH(Hanna) I checked it today and it showed 7.6 dKH(Hanna). I want to keep my levels between 7-8. how would I one keep them stable and how would I dose or...

    Nitrate or Phosphate?

    should I get a good nitrate test kit or a good phosphate test kit first? I would like to get both but I can only get one for right now.

    Enlighten me ... Randy Recipe (Alk) and Red Sea B

    @Randy Holmes-Farley if you may ... and I apologize in advanced if this has been raised in the past. By no means this is to compare between Randy's and Red Sea; I just want to understand. I was looking at your Alkalinity part (recipe #1 and recipe #2) Recipe #1 for pH below 8.3 (bake then...

    How to balance nitrate and phosphate

    Its about three months im dealing with balancing nitrate and phosphate in my reef tank and im steal dealing. This started when i saw my corals loosing their color and i asked in R2R and they say me that the po4 is too low for a tank that has LPS.So i tried to rise my no3 and po4 but i added too...

    Alk question

    I try to keep my tanks alk between 7-9 but when I use my red sea salt(not the pro) it brings my alk back up to 11. I was wondering if I had a bad batch of salt or something else.

    Raising my alk

    So my cal and alk was on the low end reading at cal-385 and alk -7.2 using regular instant ocean. I decided to switch salts and have been doing large water changes every other day however my alk is going up really slowly compared to my calcium. My calcium is currently at 420 and alk is now at...

    Mystery just showed up

    Any ideas? The shell was clean when I put it in a few days ago and I just noticed this today. I did have some feather dusters on live rock which I haven't seen for a while. This was taken through my microscope - the white part is the clean shell. Total size is 0.5 cm. Thanks.

    Let's talk about increasing phosphates.

    After my notices on my corals that every time my phosphates is at zero point,my corals first loose their colors little by little and they bleach at last. So i need a way to increase it to an acceptable range because it is 0 with hanna test kits. I tried feeding my corals and fishes more and more...

    start using kalkwasser

    Hi my friends.Ive started to use kalk for maintaining my parameteres and have watched related videos related to.The first question is that when i put the kalk in the water in a bottle and shake it,after 6 hours the water wasnt clear.Is it normal or not? The other question(not related to kalk)is...

    calcium level

    ok I tested my calcium on Monday and it was at 390. I tested it today and it was at 410 and I have not put anything in my tank to raise it. I was wondering what would cause it to do that?

    Help. Used wrong carbon

    I have brs catalytic activated carbon for rodi unit and rox carbon for my reactors. I mixed the two and just added the one meant for my rodi unit into my reactors on tank. Does it matter or can cause harm ?

    Refractometers And Salinity Measurement

    Salinity is one of the most important parameters measured in reef aquaria. It controls not only the salt balance between an organism and its surrounding environment, but also the levels of a host of ions in seawater that aquarists neither measure nor control independently. Consequently...

    pH And The Reef Aquarium

    For many aquarists, pH is not something that they have much experience with aside from their aquarium. For many, pH is almost a black box measurement: something to be considered, but whose physical meaning makes little sense to them. This article will describe pH in an intuitive way (as...

    What is Alkalinity?

    Most reefkeepers know they need to measure alkalinity, and most know it has something to do with carbonate. But what is alkalinity exactly? Why is it important? How is it measured? This article will answer those questions and give you all of the information that you need to fully understand one...

    Phosphate in the Reef Aquarium

    The phosphorus atom is one of living matter’s basic building blocks. It is present in every living creature and in the water of every reef aquarium. Unfortunately, it is often present in excess in reef aquaria and that excess has the potential to cause at least two substantial problems for...

    Nitrate in the Reef Aquarium

    Introduction Nitrate is an ion that has long dogged aquarists. It is typically formed in aquaria through the digestion of foods, and in many aquaria it builds up and can be difficult to keep at natural levels. In the past, many aquarists performed water changes with nitrate reduction as one of...

    My Triton Testing Results

    There are many different ions in seawater, and as reef aquarists we generally only test for a small number of these. Calcium, magnesium, “alkalinity”, nitrate, phosphate, and ammonia, for example, are relatively easy for hobbyists to test at home using kits. Other ions, however, are more...

    A DIY Alkalinity Test

    Alkalinity is one of the most important measurements that a reef aquarist can make. It can become rapidly depleted in many aquaria, requiring frequent measurement in order to maintain stable levels. While hobby test kits for alkalinity can be simple to use, some aquarists find them either...

    The Many Methods for Supplementing Calcium and Alkalinity

    There is no aspect of reef aquarium chemistry more important than calcium and alkalinity. Many of my previous articles have described various aspects of these systems in detail. In reading those articles, aquarists will note one pervasive theme: that maintaining appropriate levels of each are...
