Uneven floor and granite slab?

thanks! he doesnt want to use steel shims as they rust and his tank will be outdoors and a little exposed to the elements .

Hello; Not wanting steel shims and being outdoors would have been useful information a few posts back.

As far as the rust goes here are at least three ways to deal with it. One is to use stainless steel, another to use galvanized and a third is to use some sort of coating.

Looks like my input has not been worth much to you. Good luck.

hello; Took a few hours to think of this. Am I correct in thinking the stand, being metal as you have posted, is made of steel? If so then how does this work with not wishing to use steel?

since its outdoors he is worried the stand will have contact with the floor. so it will rust and weaken his stand
he's thinking of using something to raise the stand to.
so the steel legs sit on top of something that will not rust and also raise the legs from floor .
we live in a tropical country , so rain is frequent here. he has a roof but its not indoors.

Hello; I get the rust concern. You live there and likely have dealt with the conditions in homes and buildings so there may be solutions others have found.

Back to the granite blocks. The granite should have enough compressive strength to support the weight and be corrosion resistant. It may crack is the possible issue that comes to mind if the steel stand legs have a thin edge and not a flat plate of some sort to spread the load.

Here is something else to consider. If you use aluminum shims under the steel legs I would suggest some sort of barrier between the two metals. There is a type of corrosion between dissimilar metals. (I think it can set up a weak electron transfer or current more likely under wet conditions.)(think sacrificial anodes in water heaters or attached to boat outboard motor lower units.) The barrier just needs to keep the metals from direct contact.

Good luck
