Hi looking for a bit of help dosing, just starting my venture into dosing & not sure if I am over complicating things ! Had a read through Esox dosing thread & I can’t get my head around the calculations.
( maths never been my strong point ) :scratchhead:
So I’ve got a 400 L tank did a water change Sunday & carried out tests Red Sea test kits new
Ph 8.3
Kh. 8.4
Calcium 460
Mag. Showing high @ 1600

Carried out same test tonight
Ph 8.3
Kh. 7.8
Calcium 380
Mag. 1480

So obviously things are being depleted What should I start dosing at ?
Using Aquaforest powders for my solutions
Any help would be appreciated
Cheers Keith,

so lets work with

calcium @ 420 ppm
magnesium @ 1300 ppm
alkalinity @ 8dkh

so obviously there is nothing to do with magnesium just yet

Ok but the aqua forest buffers I’ve got tell me to mix calcium & magnesium as one solution

so if we work through the calcium
you have reduced from 460 ppm to 380 ppm over 3 days
80 ppm / 3 = 27 ppm / day

Checked it out & if am right it’s saying from 380 to get it upto 420 I need to dose 571ml Seems a lot ?

Hi Keith,
Hope your well?[emoji106]

Have you looked into the bioaquatek salts? Much much cheaper.

Take a look at the ReefDoser App https://itunes.apple.com/gb/app/reefdoser/id353011315?mt=8


How to Use:
Levels of Calcium, Magnesium & Alkalinity should be at optimum levels before you start. Using Balling Lite is very simple. You will need to make up the 3 solutions found below, and keep them in airtight containers, these can then be added by hand or preferably by using a programmable dosing machine to deliver the correct amounts daily.

Using the Calculator

Once levels in your aquarium are within the optimum ranges for each element, test & record the level for each one and enter it in the calculator. Then wait for at least 24-72 hours and measure again. Enter these values in second field of calculator. Finally enter number of days between readings & press calculate.

The calculator will work out how much of each element your aquarium needs per day to maintain optimum levels. You can then add to your aquarium by your preferred method

Solutions

Solution A - Dissolve 2 kg (4.4 lbs) of Calcium Chloride dihydrate CaCl2•2H2O (dowflake) in 4 litres of RO water. When fully dissolved top up the container to the 5 litre mark. To this solution, now add 25 ml of Fauna Marin Trace B heavy metal complex or equivalent plus 25 ml of Fauna Marin Trace B strontium / barium complex or equivalent.

Solution B - Dissolve 2 kg (4.4 lbs) of Magnesium Chloride hexahydrate MgCl2•6H2O, in 4 litres of RO water. When fully dissolved top up the container to the 5 litre mark. To this solution, now add 25 ml of Fauna Marin Trace B Iodine fluoro complex or equivalent.

Solution C - Dissolve 500g (1.1 lbs) of Sodium Bicarbonate NaHCO3 in 4 litres of RO water. When fully dissolved top up the container to the 5 litre mark. Nothing else is usually added to this container, though some people prefer to add the Iodine complex here rather than in solution B.

Caution: Always add salts to water first - not the other way around

This would be your maintenance dose to keep your levels stable at what they are currently at

Ideally you need to be targeting not natural sea water levels but the same levels that your chosen salt mixes to so you are not causing a major shift when you perform a water change

So works out roughly the same I think so if I need to dose that to get it to the level I want
Then do I divide that by 3 the days it took to get there & that’s what I need to dose per day to keep it stable?
Or am I missing something?
Cheers

just read there instructions
it says to dissolve 50g in 1 litre
so if you want to dissolve 80g in 1 litre you would need to check that it all dissolves
and that is your amount for 3 days so add 1/3 per day but i would test and test and test again
allow a couple of hours to pass after adding before testing

you will need to adjust as you are playing catch up initially

Cheers Mayo I’ll look into that mate only got the Aquaforest stuff as that’s the salt I use and with just learning about dosing thought I’d use a known brand
