Myka's 69 SPS Tank 2015

Nice work on the skin.
I admire people who can cut straight, something I can't do in wood.

I have a part bag of Super Reef sitting beside the tank - I might add that. It's really chunky. For now I'm just observing and see if I get used to it.

Haha! Two clamps, a 4' level, and a circular saw with a new blade.

Ahh
must b the new blade

And expertise

No Red Seal here (but enough work hours to challenge it haha)!

Look who showed up to the party! I heard some clicking, but thought it was one of the Tunzes that needs a new bushing/disc (after about 8 or 9 years I think I can deal with changing a $3 part on it). I didn't normally hear the Tunze clicking unless it was on the controller and it wasn't on the controller. Since adding the sand to the tank I haven't seen any digging in it, so I was sure Mr Clicks was a goner. I looked in the back compartment, but didn't see him (or anything really it's so dark back there). So a couple days ago the clicking was driving me bonkers so I was staring at the Tunze and the "click" sounded and the Tunze didn't do it. So I turn off the return, get my flashlight out, and low and behold there is Mr Clicks! It took me a good 30 minutes to catch him out of the back, but he's now happily digging away in the tank.





I got some work done on the stand panels. I got distracted doing some painting in the house, and decided I hated the grey color that the designer picked out. So it took me a few days and a few tries, and then I ended up going with the first grey anyway.

I got 4 coats of paint rolled onto the panels. My work space wasn't big enough to get the corners done too, so that is annoying. The panels should be cured enough by the weekend that I can use a power sander to buff the paint out and then spray a clear coat on it for a nice smooth finish. Hubby said he doesn't want a beer ledge on the stand - he just wants it to have a clean look.

I finally got a reading on the Hanna ULR Phosphorus checker! 6 ppb (0.006 ppm)! Yay.

That actually translates to 0.018

The conversion from phosphorus to phosphate for that ULR checker is

3.066 x 6 divided by 1000 = 0.018

Jess is right and faster than my splendid abacus

Well that's what I thought too, but RHF recently said that the checkers actually both check phosphate, and that Hanna just calls the ULR "phosphorus" to make it easier to differentiate. I'm going to have to go find that comment from him...oh boy this might take awhile.

[Myka]

Ok, actually that ended up being really simple...however, I didn't really continue reading beyond that part where he goes into the math of it. Thanks for the correction guys! It looks like I am right around the accuracy level of the checker, so I still just have a tiny "sniff", but at least I have something!

The Hi736 Phosphorus checker does have a somewhat better accuracy, so that would be the one to pick for most reef applications.

You do need to multiply the reading by 0.0032 to get ppm phosphate. So 5 ppb = 0.016 ppm.

Note to that the values have a stated uncertainty of 5 ppb phosphorus (0.016 ppm phosphate), so 000 ppb could really be any value up to 0.016 ppm phosphate.
