Thanks Jason, I will look at that thread. Cheers Rick............

Are there any of these levels harmful to fish or cherry and amano shrimps? I know shrimps are sensitive to copper but at these levels, is it OK? The product is API Leaf Zone. http://www.regulatory-info-api.com/PDF/LZ%...0mu%20sntzd.pdf Thanks Rick.....

Agreed...Been using one for about 20yrs. :thumbs:

That was nice of you! :heart:

I did have a problem. If you're using a recharge valve on your hoses, I found that mine sucked quite a bit of air in through the valve - the valve is very handy but really shoddy design/construction. Other than that, no real problems. Yup, that is where I thought it was sucking from.. almost needs to be on though, how else does one recharge. hmm.

Sorry to butt in but do you have trouble with bubbles with your xl? Seems like mine is sucking air from somewhere. Called vortex and they sent me different sizes of jar O-rings. Didnt make any difference. The screw top jar is poorly designed for fitting of the motor assembly. Anyways....any bubbles? I purchased the 25K bag of DE from a pool shop and it seems to work just like the powder from Vortex. Thanks
