Jackson's SPS 25 Waterbox Peninsula

E.intheC · May 19, 2023

I tested on Saturday and will test again tomorrow. I expect the phosphate to come down some.

My alk was 7.7.
Calcium 425
Nitrate 10
Phosphate 0.62 ppm !!

I use the Hanna ULR phosphorous test. I am 99% sure it’s the rock leaching as I have 2 tiny clown fish and one blue green chromis and haven’t feed much at all. The LPS corals look fine so far

Yea .6 is disproportionately high. Rock or something definitely actively adding po4. .2 or less would be something more manageable. What kind of rock did you use?

I run 4 xr15 gen 5 blue on my 80g.
I run full ab+ at 90% scheduled.
I have not ran a par test. Rack system puts the rack to surface at 12.5". Growth and color are excellent.

I like the skimmer. On my old 20 I ran skimmerless with good results.
The 20g reboot runs a 2" air driven skimmer so nothing is hanging off the tank.

I did the same with my 20. Live rock from my other systems for a no cycle start. Acros in within a week.

Looking forward to see how this grows in.

A few blue led/orange gel filter pics. Nitrates have been getting up to 25ppm easily so I increased amount of carbon dosing a bit, reduced feedings a little. Growth not as fast as I would like at the moment. Is what it is at about 11 weeks old. Needs some time.
