I like to see pics too.
Just tap water, thats the way to do it.
Sorry to go off topic for a sec, but it reminds me of an old boy I know who often told his customers the contents of his bucket was a trade secret...
The trade secret he shared with me... He never threw his water away and never added anything! No soap, nothing! Bucketfull lasted over a week sometimes Made a living for many years.
Ahh the good old days.
