Water Changes?

I use Seachem Prime in all my tanks as well. Very effective stuff, even if it does smell like rotten eggs. =)
 
rather than start another Water Change thread, i figure I'll ask this here.

I've read competing opinions on this, so I'm a bit confused.

When doing a WC, do you use enough water conditioner to treat the entire tank or just the water you take out / are putting back in.

For ex, for my 15 I do about a 25% WC a week (which is like 4 gallons). Should I be putting enough conditioner to treat the whole tank (i.e 15 gallons) or just enough to treat what I will be adding (i.e. 4 gallons).

thanks! :grinyes:
 
If you add it to the tank then refill. Add enough dechlor for the whole volume of the tank. If you treat the buckets first before pouring in, then just treat the buckets.

makes sense. thanks :)
 
I agree, it's much cheaper and uses less Prime, to treat the new water (in bucket), rather than the entire tank.
 
unless you have a pump, and use the pump to move water from the buckets to the tank, i feel like it's a fair trade to waste a little prime on dosing the whole tank just so i can use the python to refill it. under 25g, sure, bring out the buckets.larger than that and no thanks.
 
I don't use a pump. I use gravity. Not difficult to build a cheap wooden stand that raises the bucket above the level of the tank. I like the control it gives me - the water is introduced so gradually that there is no chance of shocking the fish.
 
and how do you get the bucket up there in the first place? do you fill it with a python on top of the stand, treat it, and then siphon the water into the main tank? how is this time efficient when doing 30-50% changes on 100+ gallon tanks?

Did I mention anything about it being time efficient? I'm not sure what you're trying to argue.
