I am Baaaacckkk and already need a favor...

Boy it didnt take much to push you over the edge did it.

Stock tanks are great, but the factory bulkheads suck so plan on changing it first so it doesnt leak after a month.

I didnt have luck with spa flex the one time I tried it, might of been just me, but the glue didnt want to hold it well.

 

The spa flex uses a special glue, not the same as regular pvc. I think its in the light blue can. The primer is the same as regular pvc but the glue is diff.
Yes stock tanks are great but I would build a false floor with egg create & pvc and run your input line under everything so that no detris can settle on the bottom.

Hope this helps!

 

I wondered, the geniuses at menards guaranteed me it was the same glue.

 

Its made buy the same company but it is diff.

 

I was able to place my aquarium by the cold air return duct so instead of drilling holes in the floor, I removed the vent cover and then went into the basement and peeled back a small section of the ductwork and ran 2X 1" spa flex down the opening. No holes in the floor or walls and when it comes time to take it down I'll just have a 5 minute repair job to put things back the way they had been.
In the basement I built a double stand that holds a 80g sump above and 125g gallon below. The water run into the 80 then gravity feeds to the 125 below. I though about using a stock tank but I already had the 125 and I picked up the 80 cheap. I don't have my frag racks built yet but the was one of the reasons I went with glass, plus It just seems more compact than stock tanks.

 

Craig is right make sure you replace the bulkhead. I use a stock tank and wouldn't do it any other way. As far as the flex hose you can find it on line alot cheaper than locally. It is a different glue than normal pvc cement. If you would rather get it locally go to a hot tub store they should have it.
