Alkalinity has dropped to 0?
125 tank
15 gallon sump
Mg=1440
CA=410
Temp=77.2
Salinity=1.026
PH=8.2
Reef tank is approximately 7 months running, started to see fluctuations in KH dropping to 7kh and sometimes 6kh about 2 weeks after water change.
decided to start manually dosing 2 part E.S.V.B at half the recommended dosage according to the reef chemistry calculator over the course of a day, no results, numbed it up to 2/3 and then it dropped to 6.
Panic was held off thinking I can adjust with BRS soda ash or Sodium bicarbonate dry packs.
Tried soda ash first, I had this premixed for 2 months in a jug. No changes after adding, upped the dosage then KH drops again to 5.
Water change 40 gallons!
KH is holding at 5-5.5
Next I try sodium bicarbonate, 6 oz at night and 6 in the morning then a run away train!
Today it’s 0kh
It’s obviously precipitation.
Any pointers on how to fix this?
Mixing next batch of water for a 35% water change tomorrow.
panic is setting in.
1 coral showing signs of stress-flower pot
More than usual brown algae is on the glass
I did not measure Phos yet.
Skimmer is running fine.
Started up carbon and GFO reactor today.
I normally run a month and shut off a month.
Any suggestions would be appreciated.
