the last mistake I made was a couple months ago.
Did a water change on my ten gallon tetra tank using a five gallon Sparklets bottle. I only changed about 3 gallons so the bottle wasn't full.
so then I tinkered around with my salt water tank and had to drain out a couple of gallons of water and just used the same bottle.
Then about an hour later when feeding my tetras I noticed one was missing. I looked all around the tank when suddenly the light bulb went on and I went and looked into the water bottle (hadn't emptied it yet) and sure enough there at the bottom was a dead tetra.
They don't fair to well with an almost 50/50 mix of fresh and salt water.
now every time I do a wc
on my ten, I examine the contents of the waste water before dumping, saved a couple more fish that way.
that certainly must be one heck of a ride going along 4-5 feet of siphon hose, kinda like
Six Flags for fish or something. LOL
