Ramped up my aqua ocean 8000 lph wave makers from pulse to full power see if it helps , on pulse there probably only pumping out 1/4 of full power

Sounds good!

scotty333 · Mar 16, 2024

Didn’t have time do water change yesterday, should do it later tonight

Just checked calcium since it’s been going down and it’s at 300 now!
I can only say it must be skimming out cos there nothing to use it
Kh 10 so that’s going up !

scotty333 · Mar 16, 2024

Mag 1500 so also down

Randy Holmes-Farley · Mar 16, 2024

Calcium does not skim out. These big ups and downs are likely test issues, not real changes.

scotty333 · Mar 16, 2024

Testing is consistent, checked again lfs nsw and Red Sea salt , I get the results as per salt water params

scotty333 · Mar 17, 2024

150ltrs of Red Sea salt water prepared (30%)

Results this afternoon, should be interesting, well maybe not but I’ll post them anyway

scotty333 · Mar 17, 2024

So
Calcium 315 (in line with the 300 before wc )
Mag 1500
Kh 8.6
Nitrate 50
Po4 .30

I’m getting confused and am fast loosing interest in trying to sort this out. It is not consistent.

On Monday you said calcium was 500 + ppm.

On wednesday you said it was 365 ppm

On Thursday you said it was 350

On Saturday you said it was 300 ppm

scotty333 · Mar 17, 2024

Tell me about it , it’s driving me nuts
The calcium is going somewhere but where

Lol

Test error. For calcium to decline by 200 ppm, it MUST consume 28 dKH of alk to make calcium carbonate. There is no other significant sink in seawater.

Since that presumably did not happen, it is test error.

scotty333 · Mar 17, 2024

I’ll get it dbl checked at lfs to be sure

scotty333 · Mar 18, 2024

Test results today

Salinity 1.025
Kh 9.3
Mag 1500
Calcium 350 ( buffered )
Nitrate 100
Phosphate.20

Randy Holmes-Farley · Mar 18, 2024

Buffered means added to you?

On the previous results, it is the Monday result that seems out of line and is most likely in error.

scotty333 · Mar 18, 2024

Yeah added Red Sea calcium ( 75ml) which raised it 50

Mondays result was confirmed by lfs, exactly 500+ with I think 2ml gone out a second shrine at 1ml

Randy Holmes-Farley · Mar 19, 2024

OK, well I will stand by my comment that the results are test error. There is no possibility that calcium actually dropped from 500+ ppm on Monday to 365 ppm on Wednesday.
