Hi mate, that's very kind but I'm by no means an expert compared to some of the others on here! Most of my knowledge is from reading others posts or (more often) making mistakes myself Personally I'd pick up the mag test kit and PH reader before dosing anything, because you need to get mag in order before you can stabilise alk and calcium. PH pen is not so critical but useful to have anyway.Once you've got that, take your readings, decide your targets (e.g. 8 dKH alk, 440 cal, 1350 mag) and then if mag is low, visit this site:Reef Chemistry CalculatorPut in your aquarium size, select the powder you have, then your mag reading and the target you want. Don't increase it by more than 50ppm a day. So if it's 1200, then do 1250 target for the first day. Mix up the suggested amount with some RO water and dose it a little at a time into a powerhead's flow. When you've reached your target for mag, then you can either mix up all the stock solutions and start dosing, or you can do the same as above but with calcium and alk (again, don't change them too rapidly though!). For the stock solutions, you have all the stuff for Randy's 2 part recipe #2, guess you're going with that? An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System by Randy Holmes-Farley - Reefkeeping.comIt gives some good starter doses in the second part of the article.Some suggestions:1. Don't let the dosing tubes go into the water, it will cause precipitation and clogging in the pipes. I made this mistake last week and caused a bunch of acros to strip because alk got clogged and therefore did not get dosed. Also cut the bottom of the lines at an angle2. Calibrate the doser, and double check it afterwards3. Leave 30 mins between calcium and alk doses4. Get one of these to hold your dosing lines https://www.h2oaquatics.co.uk/water-flow/bubble-magus-dosing-pump-tube-holder5. For the first week or so, test the params every night at the same time, then at least once or twice a week.
Cheers mate, noted. What makes you think I would choose recipe #2? I had #1 in mind for some reason ha ha. I think it's because Randy mentions more aquarist choose #1.I got a salifert Mg test kit today and will take readings.So get Mg to correct level and then sort Alk and Cal. If I mix my stock solutions they have long shelf life yes?This is just so confusing......A.
Quote from: jenreeferIs there a shelf life for either ca or alk after it is mixed?They will last longer than the container you put them in. 🙂
Is there a shelf life for either ca or alk after it is mixed?
Yeah recipe #1 is a slightly better choice for most, because it raises the pH (slightly!)Only thought you were doing recipe 2 because you bought sodium bicarb rather than sodium carbonate. It really doesn't matter though, cos you can bake it in the oven to make carbonate if you want anyway. These recipes don't 'go off' They will last longer than the container you put them in.
If you've got the space to store it I suppose you might as well make them up in batches, save yourself a bit of time later on?When I did this recipe, I used 3x 5 litre water bottles. I think from memory Randy's recipes use US Galls (3.8 litres) so that fits nicely in there.
All the advice is very good, get your mag up first then calcium and alk. I leave 15 mins between doses to avoid chemical mix up. I would swap the bicarbonate out for carbonate, my ph went from a average of just under 8 to 8.14 and a dailyswing of .25 rather than .31 Tim
Ph naturally rises and falls through a 24 hr periodWhen the tanks lights are on photosynthesis happens using up co2 and so your ph goes up, lights go out and photosynthesis slows so co2 levels go up making ph go down.
Yeah, here's the graph from my seneye
Alk no more than .4-.6 a dayCalcium 40ppm a dayMagnesium 60ppm a dayPh naturally rises and falls through a 24 hr periodWhen the tanks lights are on photosynthesis happens using up co2 and so your ph goes up, lights go out and photosynthesis slows so co2 levels go up making ph go down. Yes you can bake bicarbonate to make carbonate but I think you got yours from bioaquatek so the cost is minimal and wouldn’twaist my time but that’s just me If you can split your alk dose of 24 doses one a hour it will really help stability and stop any ph spikes.

This is what I do, mix you fresh water and test that for alk, cal and mag. Now that is your base line and what you need to buffer your tank too. Test on day one at a set time then on day 3 test at the same time, then take away the second test number by the first then divid it by 3 wich will give you your daily uptake. Tim
