Hi all,
As the thread says high Ca and PO4. My tank is around 6 months old. Tested today with Hanna checkers, with the following results;
Ph - 7.8
Nitrate - 22
Phos - 0.9
Alk - 8.1
Ca 600
Nitrite - 0
Mg - 1500
Salinity - 1.026
20% water changes bi-weekly. Brought from my LFS (tested today for Ca, @450 ppm)
Red Sea Max Nano, stock light, upgraded skimmer to the Tunze 9001 ( I think !) Dry rockscape, with a 1.5 inch sandbed
2 Juvenile Clowns, 2 Blue Chromis, I Blenny, 1 Pyjama Angle fish, small gathering of CUC
All Hanna checkers are new with new reagents.
I am dosing 1ml of Lanthanum Chloride once a day and I have Rowaphos in a bag in to help bring down the PO4. The tank is 6 months old and the Phosphate levels have been above
2 (we think due to PO4 being bound into my dry rock) but its coming down steadily. The tank has zero detectable GHA and looks (?) in good shape, livestock very happy, fed with mysis (small amounts) twice a day. My corals are 2 small hammers, a Gonipora, a few a zoas and a Kenya tree they are looking quite unhappy with very small polyps extension the zoas are alive and puffed up but almost completely closed permanently. So, are the above tested levels the cause of my sorry corals?
I am fully aware that these things take time to settle and I'm not rushing into anything unless I'm completely sure, but I would like to know if I should be doing anything or just leave things to settle, or am I making things too clean??
I don't wish to be a number chaser, but being relatively new to the hobby I want to prevent rather than cure
