Nano Reef Tank Uk

uk litres to us gallons for my nano tank addatives?

O.K. so I have a 35 Liter tank which is 9.25 U.S. Gallons right?
But then I’ve got about seven kilos of live rock in there! Now I’ve got Seachem’s liquid Iodide and Brightwells liquid reef( so that my corals and inverts are happy) but how much do I add when you take in to consideration of water volume instead of actual tank volume.
Both recommend 5ml per 50 U.S. Gallons of water volume, every two days.
I have an idea of what i think it may be but would like confirmation as i don’t want to overdose!!!!
Yep sorry your right 9.21 gallons! My mistake.
I figured on .5ml once a week with regular(twice a week) 20% water changes!
Any more suggestions!
It’s calcium, Magnesium levels mainly Ca+2 is 400mg/l and Magnesium is 1300mg/l.
The iodine is just to give the soft corals a boost, I have several xenia, a blue mushroom colony(8 Mushrooms, 2inch in diameter),a yellow polyp colony(twenty or so) and a finger leather at the moment but want more(ofcourse).

One U.S. gallon is about 3.8 liters, so a 35-liter tank is about 9.21 gallons, which for practical purposes we can round off to 9 gallons.

You do have quite a lot of rock in your tank, though, so you are correct that your tank has less than 9 gallons of actual water in it.

The problem with figuring out how much medication or water treatment to put in a tank is that the manufacturer never says whether the recommended dosage is based on a bare tank with that much water, or a tank full of rocks and other aquarium “furniture” (as my wife calls it). Add to that that the nominal sizes of tanks are seldom the same as their real capacity (my “100-gallon” tank, for example, holds a bit over 90 gallons of water when it’s full, with no rocks or gravel).

You could measure the volume your rocks take up, of course, and subtract that from the tank volume. Put the rocks in a bucket or other container (half-full of water) that has volume marks on the side (liters, for example), and see how much the water level goes up. Let’s say the bucket starts with 5 liters of water. Put in the rocks, and it goes up to 10 liters. So your rocks have a total volume of 5 liters (10 – 5). Therefore the volume of water in the tank (if the bare tank truly holds 35 liters) is 30 liters when the rocks are in the tank. You can do the same with gravel, little mermaid statues, etc., to find out how much space they take up and therefore how much less water will be in the tank.

But such calculations don’t solve any of the other problems I’ve already mentioned.
So you’ll probably end up just guesstimating how much of additives to put in, in any case. For various reasons, I’m not so sure the label recommendations are all that precise, anyway.
I would want to be conservative in adding iodide or any iodine compound, in particular, since it is toxic if you overdose. I woud probably go easy on the other supplements, as well. The amount you add should probably be on the low side, in other words.

P.S. Pleccy, 10 liters of (distilled) water weighs about 10 kg, but 10 liters of salt water weighs more, and 10 liters of rocks weighs far more, because the density of rocks is several times that of water, which is why (most) rocks don’t float. To put it the other way ’round, 10 kg of rocks will have a volume much less than 10 liters.
