Seachem SAFE measurement question =)

[seanyuki]

The whole tank.


For reference, 1 measure = 100 mg. To detoxify nitrite/nitrate in an emergency situation use up to 5 measures to each 40 L (10 gallons). Use fish to gauge toxicity reduction as test kits will still show presence of nitrite/nitrate even when detoxified. May be added to aquarium directly, but is better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. If temperature is > 30 C (86 F) cut dosing in half.

ps.. do you treat the WHOLE tank or just the amount of water you are adding

I treat, heat & age the water before adding it to the aquaria, so I just treat that volume of water. Seachem says to treat the volume of the tank when adding directly from the tap, although some people apparently do fine treating for just the volume of the make up water... I don't really understand the rationale for treating for the entire tank volume if you're only changing part of the water, but I don't have to understand, either.

Somehow, I like the idea of making the water safe *before* there are fish in it...

Sorry I didn't see this sooner - according to my AWS-100, calibrated digital gram scale:

1/2 teaspoon of sachem safe weighs 2.65g or 2650mg

The bottle says 5 grams of safe treats 750 liters or 198.13 gallons

2.5g treats 99 gallons

So let's go with 25mg per gallon.

For 55 gallons: 55x25=1375mg

1/4 teaspoon weighs 1325mg so I go with 1/4 teaspoon for 55 gallons. Just like Eddie and Bill said....

Hope my math is right...just wanted to "weigh in".
