I am looking onto Kalkwasser to raise my pH in order to combat a persistent dinoflagellate problem. I am also having problems with reducing consistantly high Alkalinity.
4 month old, mixed 80 gallon reef with a large CUC
, 2 percula clowns and a small blue tang.
Calcium is 460, Alk 16 dKH, pH 8.2, Salinity 1.026, Nitrates 0, Phosphate 0, Ammonia 0, Temp 78.Running carbon and GFO
in a reactor. A fluidized sand filter. Also using a Pura filtration pad in my wet/dry. I am also pulling about 1.5 cups of horrendous skimmate every day.
Mistaking it for cyno I treated the tank with erythromycin followed by UltraLife Red Slime Remover 1 week later.
I have replaced 100% of my water over the past 3 weeks with RO/DI water changes (reading of 0 on a TDS meter, culligan water) using IO Reef Crystals and added no buffers or supplements of any kind. I have also left the aquarium dark for 72 hours. Suspended feedings and added a magnum canister filter filled with floss in hopes of pulling out the suspended dino. Alk is consistenly very high and the dino is as bad as ever.
's look aweful and the GSP and Xenia are completely withdrawn/stressed.
Will Kalkwasser help? If so, do you guys hand dose or use a Dosing Pump?
I have read about slightly detectable levels of nitrates controlling dino.
I wonder if discontinuing the sand filter would allow enough of an increase in nitrates?
