PVC cementing is a two part process, yes the primer cleans the fitting and pipe, but it is cleaning away oils, dirt, ect and the factory coating on PVC pipe and fittings. Also it acts as a bonding agent by making the surfaces softer allowing the glue to react and soak in to the PVC farther creating a stronger bond.

As for low PSI systems not needing it, PVC is only meant for low PSI systems, the 145 PSI cold is a max pressure, 99.9% of all PVC systems operate at under 70 PSI and probably the majority of that under 30 PSI which is where tanks can operate.

as for getting away with not using primer, .. ya you could, but you would have more leaks with out primer than you would with it. this is a design process shortcuts can work but they are never the right way to do anything.

for people who don't want the purple ugly primer look, (the main reason people want to not use primer) get clear primer and clear glue.

well now that I am placing the stand for the 240glns there is a gap if aprox. 1/4" on the bottom of one side of the stand.
What should I place under there to level the stand? Someone said use pennies or a piece of metal? would that be fine of would I run into problems later on?
any input would be much appreciated as I am planning to start filling the tank tonight.

Metal shims would be my choice or oak shims.

Thanks Greg I will go and find some scrap metal now

use composite shims-about $4 at rona or home depot.they won't compress or rot or rust

I don't have any metal scraps so off to home depot or rona tomorrow to find either some metal or check out the composite shims or any other product that could handle the 2400lbs weight

the stand is ready for placing the tank and start filling (tomorrow's job) in the mean time the 180,the 60 and the 40glns are running with only 180glns has few corals.Here are some quick snaps,oh and I haven't painted the back of the 180 yet

During the wait and all the construction I think I am having a problem of what to stock the tanks and how.like some of the photos shows I will have the 240 slightly over laps the 180 on the over flow side.
Well here are a few ideas if the stock.
So I am thinking a high rock slide for both tanks going down towards white sand.
I think a floor full of zoas and polyps of all different colors and shapes.
Then on the rocks a couple Blue orange stags and few acans...
Now I am lost for stocking the 240 glns ideas ideas ideas....

I think ricordea and zoas of all colors will soon be on the way for stocking my tanks and few pieces for those of you interested parties....
