#1: I am making an inline, PVC, CO2 reactor. I have most of the stuff I need to do it, including 2-in-1 primer/cement. A plumber friend of mine has been telling me horror stories about the chemicals in the primer. Including the fact that they leach into the water flowing thru the pipe, for some time. Do I even need to use the primer? Or, can I just clean the end of the pipe, scrape it up alittle, and use the cement only? But, If I do need both, is there a "safe" brand, or type, I should use?

#2: I have a Fluval 405 canister filter which I have heard puts out 350 gph, from the return line. I had planed on splitting the return line and running them to 2, 20" long spray bars that will be placed vertically in the 2 rear corners of the tank. The spray bars will be 3/4" clear acrylic pipe, that I will drill 1/4" - 1/2" holes in, along their length, every inch or so. Will the 350gph output be strong enouph to handle being split and squirted out of several holes, in 2 pipes? I'm trying to do this in order to improve water circulation in the tank. I'm sure it would be easier to hook the spray bars up to a submersable pump, but I am trying to keep as much equipment out of the tank as possible.

I know thats was alot so, thanks for your help.

ive used primer on my ponds and have seen no problem as long as you let it cure properly once glued

When you prime and glue you do not need to use a lot. There is not much pressure and the glue is quite strong. You are actually melting the plastic together. Put the primer on each piece and get a good coat just don't let it end up getting where the water is and you should be fine.

Yeah, but has he stopped using it? Particularly in areas that require purple primer to prove to the building inspector that the joints were primed and sealed?

Plastic pipe primer -is- nasty stuff and should not be used in an un-ventilated space. The chemical(s) -can- contaminate drinking water in small quantities. So, use it in a ventilated space, Use only enough to do the job, and flush the assembly with water before using it on your tank(s).

i got it where the water is in my pond and my fish are doing fine

Geez, I don't even use the primer. I just use the glue, let it cure for 24 hrs and just rinse it out with hot water. I've acutally used pieces that only cured for like 30 mins when my pump burned out on my sw tank. Never had any issues with leaks or contamination.

it says it cures in 30 min but for fully cured and safe with higher pressure you should wait 24 hours
