I've had the recirc heating running for about an hour now.
Incoming water temp is 91.9 F, outgoing water temp is 77.9F Present water temp is 75.6 F, so the aquarium water is taking almost all the heat that is being put through the coils. I didn't do any calculations to arrive at how many coils, just my best estimate. I put in 5 coils with a 20" diameter. We'll see how long it takes to bring the 700 gallons up to the target temp of 79 F.

Quick question are those copper fittings on the pump?

Here is the hookup to the hot water tank:
Hot water exit is coming out of the top middle of the hot water tank. The red PEX pipe attached at the "T" fitting is leading to the recirc pump which pumps to the coils in the sump. The cold water supply line to the hot water tank runs down the front of the tank out of the picture. The white PEX pipe at the "T" fitting is coming directly from the coils in the sump. The loop follows: hot water tank -> red PEX -> recirc pump -> coils -> return line to the cold water supply -> water gets reheated and goes through the loop again as needed.

I've bleached 2 40g pails of LR and let them sit out in the sun and rain for a couple of weeks now.
Today was acid dip day. I have about 50 pieces of live rock to do. I bought some nitrile gloves, muriatic acid from Canadian Tire and had some baking soda on hand in case I splashed something on myself. I put 10 liters of water and 1 liter of acid in an old salt pail and had a rubbermaid container full of tap water for rinsing. It was actually a pretty tame procedure. The smaller rocks foamed a bit but didn't overflow the bucket. I left the rocks in the acid dip for 3 minutes each. I tried to put in about the same mass of rocks each time. I did about 10 batches per bucket of acid dip then I dumped it out and started with a new batch. After 10 batches, the foaming was minimal so the PH had risen quite a bit and the solution was close to neutral. For the larger rocks, 11 liters didn't cover them, so I did them at the end. I just added additional 10 liters of water plus 1 liter of acid. That covered the rocks, but also overflowed the bucket. Definitely an outside project! Tomorrow I hope to start drilling and stacking the live rock with some acrylic rods. Gotta get this show on the road.

I got the tools ready for tomorrow and tried out a test piece. It worked pretty well. I'll put an old towel in between the rock and the workbench so the rock doesn't get vibration from both sides and break apart.
