A heat exchange unit?

Yup! The plan is to run a re-circulation pump from my gas hot-water heater through it and use it to heat the sump. I did some rough math and it should save me about 40% on my heating.

Wow, interesting idea on the pump. Would that be in the water out would it just be Pex lines coiled inside?

I was originally just going to coil some Pex into the sump but I read that having all that water in the coil sitting at 25 degrees isn't ideal (legionnaires) especially since it's returning back into the water supply. That's why I went the heat exchanger route.

The fish room is an unfinished bathroom in the basement so it has the hot and cold lines already there. The plan is to use those as the loop back to the hot water tank using one of these:
Watts Recirculating Pump

So here is the design I'm thinking:

That"s one of the best corrosion resistance ss. However, it will corrode as well in saltwater, albeit very slowly.

Since I'm going to put saltwater through it I had to go with Titanium for exactly those reasons.

Next up on my immediate list is figuring on my aquascape. Since my tank is so tall I'm going to need some very high structures but I want to keep them very long and narrow. Something like below but having it raised up about 12 inches.


Or


Anyone have any experience making something like this? I'm thinking of smashing up some dry rock, using PVC or Acrylic rods then using Marco mortar to stick it all together?

I recall the tidal garden guy having some youtube reference to a "guy in asia doing a floating aquascape"( don't remember which youtube of his but had some link ) but you can see this show tank he is working on in eps 1.
https://www.youtube.com/watch?v=C_3zTB6Fllg . His tank is similar to your except deeper. You can always ask him a question as he is quite receptive..he was on reefdudes not long ago.

...and from tidalgarden https://www.youtube.com/watch?v=8MfhEFRTgk4, his link is to some guy in korea using marco dust and glue: https://www.youtube.com/watch?v=YabRU1LYDY4 there are some other related links as well from there.
