So we are a couple of months further, after the cleanup.
The thank is doing well, for the moment.
Water values are fairly stable , the last 2 months, and corals are nicely open.
Water values as of last weekend, after water change,
Temp. 25 C° - Alk 9.4 dkh - sg 33ppt - po4 0 - no3 10 - ph 7.8 - ca 385
Sg is low, but I think my refracto meter is broke, I always calibrate with refracto check liquid at 35ppt, my freshly made water is at 35ppt , a day after waterchange it’s always 1 or 2 points lower, and I don’t think it’s my ato.
Ph is measured in the evening, and is low, but the ph pen is not calibrated.
Po4 is at 0,03 before waterchange
No3 is mostly at 10
Alk is mostly around 8.8
Ca 385 is on the low side, measured this for the first time yesterday
All corals are looking good, and are nicely open , with these values .
I’m thinking to start using all for reef, but I look also in the direction of kalkwasser , mainly to raise my ph a little.
