Can I Add It This Way?

[memojo1979]

I've bought some more water treatment today, so I can now top up the water in my new tanks (they are only 1/2 full, as I only had 2 + a little bit bottles of treatment, but each of the 2 tanks looks like it'll use 2 whole bottles).
I know each bottle will treat 57 litres, so with the 3ft tanks I just measured out 57 litres (5 x 10l in a bucket, then the additional 7l) + added the water treatment along with 1 of the bucketfuls.
However, my axolotls are currently in the tanks, so I'm thinking of temporarily housing them in buckets while I add the water.

Now for my question - can I add the treatment the same way as before (using a whole bottle in 1 bucket, then adding the rest of the untreated water to the required amount), or do I need to add the right amount into each bucketful of water, bearing in mind there is already cycled water in the tank? Will the existing water affect the effectiveness of the water treatment being added for the fresh water?
Does that make sense?!

I've taken mine out before, whacked the water in then whacked the right amount of treatment in if that's what you mean? I figured it would work the same, I hope I was right! Now though I just use bottles and pre-treat the water before adding it, unless I'm being lazy or have lost my syringe

I guess I could use 1 of the now-empty 3ft-ers to mix the water in, just to make sure. I never thought of that before, LoL! I can measure the water using the bucket, chuck the bottle of water treatment in it, give it a good 'ole mix up + then use the syphon to transfer it back into the bucket, to add to the 4ft-ers. Doh!
Still, it'd be nice to know for the future. Ta for your answer Star

Well, using 1 of the 3ft tanks was NOT a great idea - it took longer to empty it all out again (using a siphon) than it would've to just measure the amount for each 10l if I did it a bucketful at a time
Thankfully, I won't need to do it again though - I can just do my usual 2 bucketfuls each change (was 1 bucketful for the 3ft tank) instead :happy:

Lol unlucky there! I find my 5L bottle trick easy
