Looks good!View attachment 32396500Cloudiness is gone. Lights off for cycle
That looks much better.Did baseline on calcium and alk for new mix. I’m thinking that it was user error on the high calcium reading originally. I mad a mistake running it a second time and perhaps put in too much salt water into the test mix. I almost did it on the control sample
Calcium looks better at 456
Alk at 7.7
I've run (and still do) MH since the early 1990s. I've always had to use heaters as I keep my tanks in the basement. So, even in the summer, my heaters run.I’ve never used one either. Or for that matter, didn’t need a heater.
My 92 gallon has MH lighting and a glass top. It was marginal to need a chiller. As long as I kept the house on the cool sid. It ran in range for temperature. I had to watch for it to creep up though.
I don’t think it was entirely the MH. But rather a combination of the 250W MH on a corner tank with a lid. didn’t know any better on that tank. It had a glass lid and the fixture sat right on top of the lid.I've run (and still do) MH since the early 1990s. I've always had to use heaters as I keep my tanks in the basement.

Got me reminiscing again. Back in the 80s, 200 gallon fish only tank. 20 gallon tank for sump, we took plastic trays and cut slots in them, filled them with crushed coral, stacked them atop each other and placed in the 20 gallon tank. Then, (since reef ready tanks were not available) we had a homemade HOB overflow going to a PVC spraybar that distributed the water over the top tray to trickle down to the rest.That tank was started when bioballs were the thing. It was a 92 gallon corner. I converted the bioball canister to a small refrigium then later put a 10 gallon with baffles underneath. I had to watch the level below closely to prevent overflowing when we lost power. And it was very noisy.
That aside, I think the natural temperature of it was a combination of things. Glass cover with a MH fixture on top of it. And it was on the main floor, which is warmer than a basement for sure. It was marginal to need a chiller
