Stand for sump

I don't think poly will stick to the CCA soaked wood very well at this point, unless the mositure of the PT wood is very low. Dave's picture shows the wood still very "green".

This answered all my questions... It says that you have to use oil based paint to seal the PT wood. Check it out...

Where can you find oil-based paints, not legal in New York or Pa, I don't know about Ct.

I dont know about regular paint in NY, but you can def get oil based primer. Maybe a few coats of that will do the trick???

I would use either Killz or Zinzers oil based primer with 2 coats and then cover it with the plywood and poly that.

Thanks for this post

If it were me, I would just start over. Health of your family and reef are more important than the cost of wood

This is very true, that was what i was going to do,but masterswimmer made a good point,most decks in our houses are made of the same wood. i don't see every one removing the pt wood from there houses, plus my kids are never in the basement. it's cooled and humid down there and they suffer from asthma. so we don't let them go down there much. they stay in the ground floor or upstairs most of the time. But i really appreciate your comments.
Thanks.

Dave, here's a pic of House of Fish north. We used PT lumber for the posts. Like I said, I wouldn't remove them and I stand by my word because I used them in my own application. I only used PT posts because they come in contact with the cement floor. That is the place that rot would normally occur in any construction (as the link above said as well). I practice what I preach

How will you fit the forklift in that room to move it? :dead1:

Looks good Dave.

And the sump. Thanks to Paul (kimoyo) for the nice work

In reference to the pressure treated wood, the ACC treatment was phased out for home lumber in 2003. The new treatment is alkaline copper quaternary (ACQ). No more arsinic, but more copper. The problem is that the extra copper is very corrosive to fasteners that would have worked fine in the old ACC.

You should use stainless steel fasteners or fasteners that are stated to be "ACQ approved".

Other than that, I think you are fine, since your sump is above all the lumber anyhow.

That certrainly looks sturdy and the sump is beautiful.
I especially like the angelfish you have in the first compartment - sooo pretty!

One question - where is the tank going...upstairs?

 

[masterswimmer]

Dave, is the chamber all the way on the right where you're going to drill into for the return bulkhead? If so, then that chamber is very small. It is where you're going to see ALL your tank evaporation. Your ATO is going to kick on very frequently.

originally i had a sump down here and decided to move everything under the sump upstairs,, big mistake... so everything is coming back down stairs and the tank will stay upstairs.....

yes it is, i was aware of that. but being that it's norrow but long maybe it won't be too bad. my only concern is wether i will be able to get a 1 1/2 inch bulkhead inthere if i need to. thanks again for pointing that out russ

 

[Dace]

thanks for the info. it's alittle late but maybe i can switch them over in some time. I'm alittle tired right now
