How much do you dose?

With more volume, you have a greater reserve of those important elements, no? Most of our systems are in a constant state of change, with livestock growing, dying, changing... so I reckon testing is a good thing, particularly if you've invested many $$$s in pricey coral. I think that's why I may be getting away with my lackadaisical testing/dosing routine, I enjoy my tank, but if I'm stressing over it due to a monetary investment, that enjoyment tends to fade quickly.

ppm is ppm so a 1% water change on a 100 g tank with a calcium of 450ppm Will replenish the same as a 1% water change of the same on a 1000g tank


In respect though the animals use this , so a larger tank may often use more and require more but only if the animals that use it have higher demand or are more in numbers which is common as the ecosystem is larger

A 100g packed sps tank will likely have more demand than a new 1000g tank that has nothing in it for quite some time, it really comes down to who uses it and how much of it they use each animal and species is different and have different demands

Thank you for everyone's input...obviously I shouldn't be worried about what I'm dosing yet as it isn't as much as I thought. I will continue with some steady bumps and measure to see how it's reacting.

Thanks I looked for the conversion before I posted, couldn't find one.

My question is how much do you dose per day? I'm currently dosing about 290ml of Alk per day and I'm losing ground. My CA is also high...so I'm cutting back my dosing there.

Just thought I could get some examples of what other people have to put into the tank each day.

Hey Mark, your dosing doesn't sound unusually high to me. My old 90-gallon tank when it was setup SPS only I was pumping just under 125 mL per day into the tank and I had less than 100 gallons of actual water volume. I was using Fauna Marin sodium bicarbonate and I mixed it 125 grams per liter.
