Hypothetical Question

[the_lock_man]

I was musing to myself last night as I was finishing off my water change.

I use the lovely bucket method of waterchanging, obviously I fill my bucket with conditioner and water, and fill up my tank. I wondered what the situation would be if I didn't completely fill my tank back up (ie I'd taken out more water than I put in).

If I then went and refilled the bucket, to top up the tank, would I need to use conditioner in the extra water, or is there enough conditioner in the newly-filled tank, to remove the nasties from the extra water?

Hi,

I've never thought that water conditioner for any changes less than 30% was necessary.

if you use enough
dechlorinator in the
first bucket to do the rest
of the buckets your going to
be putting in that would be fine
i never put the dechlorinator
in the bucket any way always in the
tank and always enough to do the refill
i always have the tendency to go slightly
over with the dechlorinator but only by
the smallest amount

Some people do not bother using water conditioner if they do 25% water changes something I do not do myself but as far as your question goes you would be fine with a single untreated bucket

I always add dechlorinator to even the smallest amount of water just to be on the safe side

After waiting 50 long days for my tank to cycle I`m not taking any chances so I always put 25% extra conditioner in anyway

My only question would be, why risk it?

People know there's chlorine in the tap water, 5 ml per 10 litres (bucket size), takes 5 seconds to add so why not just chuck it in?

I realise that my tanks are tiny (largest is 54 litres) so my 20% change is only one bucket but I would guess that on a 125 litre tank any amount less than about 5 litres wouldn't make a significant difference if topping up so you're gonna be adding about that or more. Easy enough to measure the dechlor then and chuck it in with that extra bucket of topup. Guaranteed no chlorine related stress for the fish then.

I always add mine to the buckets whether it is a full one or half a bucket. I would not risk my fishes health

I add and remove water with a hose so if I take out x amount of water I put the same x amount back in the tank and I add x amount of conditioner in. I used to be extremely careful with the amount of conditioner I put in making sure every bucket of water I put in had exactly the write amount of conditioner for the bucket.

But since reading how others do it here especially those using pythons or home made pythons I had to give it a go myself , I still have my two buckets but only use them to put the rocks and ornaments in.

But I understand what people are worrying about I used to be the same when I was new to the hobby, of course we all have to do what we think is write for ourselves and more importantly our fish and I CAN ASSURE YOU MY FISHES HEALTH COMES FIRST! but I will stand by my statement one bucket will not hurt.

Good luck regards onebto.

Seconded

Using something like Seachem prime which is a rather strong conditioner on a 40 litre tank where you do maybe a 20-50% water change is almost impossible to measure without a medical syringe. Therefore I usually over dose the first bucket and don't put anything else in the second bucket.

Also keep in mind the process is not instant anyway.

Absolutely. Why take the chance.

Hi, If I aren't mistaken I'm certain that one of our very own mods (Simonas) has said before that he doesn't use dechlor at all. He is one person that always has healthy, stunning fish and never seems to complain or post of any issues. Well none other than leaving the hose running anyway

 

[Aqua Tom]

Are we talking about water dechlorinators here?

 

[the biffster]

i think so i forgot

 

[onebto]

yep dechlorinators that's what its all about lol
