    Suspecting Metals/Chlorine in LFS Water. Should I Use Contitioner?

    So I'm having a suspicion that my LFS might have metals or chlorine in their water. I finally decided to order an RODI unit, but it's going to take about a week until it gets here and I can make new water. Should I use water conditioner or wait it out? I've never used it before, but corals...

    USING HANNA CHECKER HI-707 TO TEST FOR IODINE

    USING HANNA CHECKER HI-707 TO TEST FOR IODINE In my quest to improve my testing accuracy and precision I found the standard colorimetric tests for Iodine difficult to get any kind of accurate reading and the repeatability (precision) was not very good. Being that I dosed Iodine this made me...

    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...

    Alk climbed/precipitation in dosing container

    I had alkanity spike pretty high recently in my tank. I'm thinking maybe I didn't rinse my dosing container the last time I added new soda ash/calcium chloride? There was a good amount of residue in the btm of both containers and in both dosing tubes. I test Alk usually every other day and try...

    Calcium Chloride question

    I've been starting to use Randy's recipe #1 for my mixed reef tank. Like many other folks, I have been unable to find Dow Flake anywhere around me. However, Lowes carries SafeStep Extreme 7300, which the company fact sheet lists as "pure CaCl2". I mixed my first batch today and all dissolved...

    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.

    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?

    No water change reef tank?

    I recently have been spending time learning more about no water change systems that I have known about for years. Does anyone have any information on these or feedback? I am planning a HUGE reef tank and a no water change system like this is very appealing. One company I came across was this...

    Red Sea Salt

    why can't I find any reviews on red sea salt. all I can find is red sea salt pro. does anyone on here use it? I just got some because my alk is to high for my system and I don't like doing a water change and it bring it back up. i'd rather keep it low at like 7-8 and not at 12.

    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...

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...
