Why you should use biocide pt. 2 **WARNING: graphic!** also, pump disintegration...

[NaeKuh]

Uh oh it looks like I had a major problem with my pump and I didn't even realize it... the stuff isn't just algae slime, there are PLASTIC SHAVINGS all over the thing and the edges of the impeller are rough (

its platicizer sparky..

nothing to freak out about... and it was most likely in solution until u drained it, where though friction it got deposited on the walls.

Martin, but isn't tap water not safe, warm or not, since it contains lots of minerals?

How safe is that? Especially when you're mixing metals in your loop.
Don't think that is such a great idea. Sure it's convenient, but not safe.

to wash, its fine..

i do it all the time, because you wont get 60psi though anything but city water line.
And you will require that much psi at times to push lodged stuff out.

Its important that you rince tho.

As martin said, it has a lot to do with your city water supply.
If you live in france where its heavily flourated, i wouldnt risk rincing anything out.

If u have hard water, once again, calcium despoits are a PITFA, so i rince out.

I would never fill with city tap water tho, over time if u let it out, it starts to smell bad.
That itself should tell you the quality of water.

Now if i lived in Des Moines, Iowa; Austin, Texas; and Sioux Falls, S.D., i wouldnt mind using TAP water as long as i kept it topped off, and flushed frequently..... As those cities probably have the cleanest tap water.
