Cinderblock tank

[Scottkelly911]

I was checking out some of the crazy sized tanks over at Monsterfishkeepers.com and was wondering if this type of a tank is feasible for a saltwater aquarium?

I think it definitely seems like a good alternative to some of the wooden tanks that people have been building.

Seems to me that the hollow blocks are filled with reinforced concrete.
If properly sealed on the inside it shall work with no problem.

There is a store in Cincy that has a shark tank built in a similar way.

I would think the PH would be off

If you covered the walls with an epoxy product like sani-tred or pondarmor or another item like those then the blocks should not affect the PH of the water...

I wouldnt think ph would be affected if the concete is sealed off by a piant or someother kind of water proofing. It looked to be coated with something, if you noticed it was blue on the inside. I would imagine the concrete doesnt even see the water.

That is awesome, I thought only us reefers were insane!
With a good quality Epoxy seal it should be no problem.

This is the sani-tred product...
