    By MarkJay,

    Hi, name is Mark and new to the Reef world, ordered the Red Sea 170 Deluxe which is due to be delivered middle of next week, also had the Magnus C5 curve Skimmer, SW-4 & SW-8 wavemakers, Dcs-4000 pump, and a heater, very nervous about making sure I set it up correctly. I hear reactors mentiond a lot is this something I need to also get or add at a later date?

    looking forward to reading through the post learning and seeing some reefs for ideas

    Dosing made simple

    By mrdave,



    I thought I would write this post as there has been a few questions of late regarding dosing. This is my take on it and not set in stone but it works for me.

    If there is anything I have not covered or something you do not understand then please let me know.


    Why do we dose ?

    We dose our systems to ensure the optimum levels of the 3 main foundation elements are kept stable to ensure the health and growth of our delicate animals are kept at an optimum.


     Foundation elements are:


    1.  (Calcium)

      Ca is an essential element for the growth of our corals, inverts, clams, LPS and Sps It is key to keep Ca stable and at the optimum level.


    2. Alkalinity

      The alkalinity is the waters ability to resist Ph changes. In our systems the animals constantly release acids that would without buffering the Alk drop the Ph


    3. Mg (magnesium)

      Magnesium is a very abundant element that keeps the Ca and Alk  (dKH)stable, the chances are that if you are struggling keeping Ca and Alk (dKH) stable then the Mg is not balanced.

      When magnesium is too low then Ca generally precipitates and is not taken up into the water column. If the Magnesium is too high it can have an adverse effect on the inverts and pod life in the system.



    Knowing our system


    Before we start dosing we need to know our systems uptake and requirements. We do this by monitoring our system. Perform a test and log the results, wait 3 days then test again- simply divide the drop by 3 and you have your uptake.

    There are many products on the market and you must apply their calculations to get the correct dosage.


    Setting up the doser

    Locate the doser above the dosing vessels and ensure non return valves are placed on the intake and delivery  end of the pump.

    Ensure you follow the manufacturers instructions and calibrate the unit before use.

    Make sure you cut the end of the tube in the vessel at approximately 45 degrees this will prevent the tube creating a vacuum and sticking to the bottom of the vessel and not dosing.

    The delivery end of the tubing should dose into a high flow area typically the return pump section, this will ensure the chemicals are well mixed.

    Dosing Sequence

    1. Ca (Calcium)

    2. Mg (magnesium)

    3. Alk (Alkalinty)


    Leave a minimum of 1 hour between doses to make sure the liquid has been circulated through the water column to prevent precipitation.

    If you are dosing amounts over 30Ml I personally would split them into 2,3 or 4 doses depending on the amount and in sequence with the other chemicals.

    Monitor your system after a day and record the results this way you can tweak the amounts to ensure stability.


    I would always advise to keep your parameters in line with the brand of salt you are using and remember



    There are many other elements we can and do dose and I will do another thread on this at a later date

    Mixing RSCP

    By mrdave,

    Technical Notes

    Technical Notes:
    1. Coral Pro was specially designed for enhancing the calcification process in all corals. It contains elevated levels of the foundation elements (calcium, magnesium and the carbonate alkalinity components) and is recommend to be mixed to a salinity of 35ppt. The combination of high levels of foundation elements and salinity makes the elements close to their natural saturation levels in seawater enhancing the possibility of precipitation.
    2. The raw materials used in the latest formula of Coral Pro dissolve much quicker than in the past and even if the seawater is not to be used immediately, it should not be mixed for much longer than required to dissolve the salt. In fact Coral Pro salt has gone from being one of the slowest salts to dissolve, to one of the fastest, particularly when taking into account the levels of the foundation elements for the accelerated growth of SPS corals.
    3. Due to the thermodynamics of the dissolving process of the salt formula, water that is significantly cooler or warmer than the recommended 20oC/68oF will slow down the mixing process. Warmer water is a contributory factor to causing precipitation of the foundation elements making the water cloudy.
    4. Mixing the salt with high agitation at the water surface increases the amount of CO2 that evaporates from the water causing an increase in both pH and alkalinity that enhances the chance of precipitation.
    5. The built in inaccuracies of home measuring tools (weighing the salt, volume of water and quality of hydrometer/refractometer) may lead to a salinity of 1-2 ppt more than desired, increasing the chances of precipitation.
    6. Due to excessive vibration during shipping and the different particle sizes and weights of the various elements in the salt, sometimes the mix can lose some of its homogeneity. This can lead for example to higher calcium levels at the top of the bucket which can cause precipitation (cloudiness) on mixing. Dry mixing the contents of a bucket will restore the original homogeneity.

    Mixing instructions:

    Mixing Instructions:
    1. Use RO water that is at ambient in the UK a temperature of approximately 20C/68F is optimum .
    2. Accurately weight the salt and measure the volume of water according to the salinity you wish to achieve.
    3. Pour the salt gradually into the water. Do not pour water onto the salt.
    4. Mix vigorously (without aeration) for approximately 0.5 - 2 hours, until all of the salt is dissolved and pH has stabilized to 8.2 – 8.4 - DO NOT mix for more than 4 hours.

    5. When mixed, raise the temperature and add to the aquarium. (Not absolutely necessary for a small water change)

    Any further questions feel free to ask, I should point out that it is highly recommended to dry mix any brand of slat as they can all suffer from possible stratification.

    By Ripcurl67,

    Hello guys,

    Need some help on finding out how much jbl silicate remover to add to my dd cannister reactor?My tank is a 260 ltr with no sump.It says on the instructions book to add a max 1 mg/l

    How do i convert 1mg/l to grams or kgs as i will need to measure this out to add to the reactor.

    Many thanks in advance guys.


    Setting up a holding/QT tank

    By DJ23bol,

    Hey guys so with setting up my new tank I will be going with dry rock and trying to keep unwanted pests to a minimum so I've got an 100l tank that I'm thinking of turning into a coral/fish holding tank so that I can inspect and monitor them for a month or two before adding them to my main reef.

    I do have a carrier bag of alfagrog that I'm planning on using in the rear sump as the tank won't have rock in I'm going to make a frag shelf unit with 2-3 tiers and add some pvc tubing for fish to hide in.


    So has anyone any advice or tips this will be my first holding tank but I've been toying with the idea for a year or so after having nudis come in on some zoas I bought in the past. Also a friend of mine got some zoas from a fish shop in Manchester and they had nudis aswell.


    I know that there's always a risk when adding new inhabitants to your tank of introducing a nasty or bug of some sort but I would just like to reduce this risk, i will also be dipping new additions before they go into the holding tank.dc5d56cebc16552251474e81ab65172e.jpgc13553becd34fd09d289a788cdae41a6.jpg9d4adc354ee774a89ea328cf55dacb23.jpg

    By mrdave,

    Gents firstly I must apologise for my lack of activity on the forum, Ive been hectic as always


    I have had a chat with @W3bbo regarding the forum and forums in general.

    As we all know the forums are taking a major bashing from facebook and getting slower and slower. Whilst we do have reef face facebook and twitter along with our other facebook group "Red Sea All the Way" our main focus is on the forum.

    We have no intention of giving up on it as for many years now we have had a good solid user base and given time I truly believe that the forums will pick up again.

    If you have any ideas or wish to contribute in any way to the forum please let me or W3bbo know.





    Chaeto Reactors compared to Algae Scrubbers

    By SantaMonica,

    With more people wanting to use natural filtration for their tanks, we are going to look at the two main types of units that you can put on your system: Chaeto reactors (or "algae reactors") and algae turf scrubbers (ATS). We won’t be looking at refugiums however, since those have mostly a different purpose. This will be a multi-part post; the next post will start with the basics, so if you’d like anything in particular to be covered, let us know.
