Brad stated he added 5ml of Prime to his 50g tank. If what I'm calculating is correct, it will not make any difference at all.

Is my math off ???

If 5ml of Prime in 50g of water removes 1mg/L, and there's 189L in a 50g ( give or take), doesn't this mean that you would need to add a whole lot of Prime (close to a litre of it) to remove that 1mg of Ammonia?

189 * 5 = 945ml of Prime

This tells me you would need to add almost a litre of Prime to remove just one mg of Ammonia in his 50g tank.

Am I missing something here, or is this why people overdose Prime?

Would someone show me how I am off here, or confirm my math?

I dont see why people have a problem with this. It's only temp. Also if the fish are showing no signs of infection or bad bacteria then no problem. If its long term them fine. It not like every one is going into certain lfs going you can't keep that fish on there because a 3 foot by 18 by 18 inches isn't big enough for that fish.
If your water is stable. And its only for short term. And they remain eating. Look healthy.
Then it's really Just keeping up keep.
For thoses of us in Calgary how about looking at the angel, orange shoulder tang, and clown tang at a certain local fish store on 16th.

I'm not justifying nor am I saying its wrong. In a few years it might be impossible to get any saltwater items.

Sorry for the bad grammar.
Also for the noted I have had a lot to drink tonight.
Looking forward to the plumbing I did hopefully it hold without leaking.

The question to be answered here was;
"is the math off on the Prime dose?"

Cheers to your plumbing holding up bud :drinking:

I've plumbed during beers when I shouldn't have :happy:

Thanks Shelley, but it's looking better. NH3 down to under 1.0ppm, and I'm going to connect it to the sump now.

I don't think anyone is having a problem with this, as it is a temp solution. Circumstances being that these fish were only available now due to a tank shut down, my schedule got pushed forward a bit. I've actually found everyone quite helpful, and even Naesco hasn't tried arresting me :)

ok, 5:30am and I've got the sump hooked up, an extra 10lbs of rock and an ER RS180 running for now. I'll let the skimmer run for the day and then turn it off to medicate the tank (assuming NH3 goes to 0).

Leaving for the day, NH3 sitting at 0.25ppm. Looks like it's going down.

1mg/L refers to concentration of NH4. Not dosage. So you don't need to time 189L. Actually since Brad has (had, since then he connects the QT to his sump) 50 G, he only needs to dose 5 ml to lower the whole tank of NH4 by 1mg/L (theoretically).

Just got home, tank is still sitting at 0.25ppm, so no increase over the last 12 hours. Good thing. I'll change some water later on, not sure there are any stores open tonight to find more prime. Fish all look fine though, so we'll see what the next 12 hours brings.
