Hi Bob,

I have just read your book Live Sand Secrets Revised 2nd edition and I'm setting up a marine reef aquarium - 72" x 30" x 30" and would like set it up with a live sand Plenum System. I have retired to Thailand, where it's a bit of challenge for me to have marine aquariums. But it's not the first time I have kept Marine fish as I have kept them years ago when all you had was undergravel filters. Could you e-mail me the details of the company that makes custom-made plenum assemblies, as I would like to try and get one of them. Looking forward to hearing from you soon.

Hi Colin,

It’s been a long time since I’ve been there (Bangkok) and bet things have radically changed! In fact, I can remember visiting the King’s Palace and some of the local temple ruins.

As for setting up the plenum, if any questions arise, don’t hesitate to contact me. In fact, you might want to tell me where it’s going to be used, i.e., in the show tank or an interconnected tank, as it ‘does’ make a difference. And there’s been some tweaking since that booklet came out, so if possible, lets discuss your plans and I’ll try to help so it all goes correct the first time around.

For the custom-made plenum grid, contact Todd Schwarz at and discuss your need.
