Hi everyone , I have a 150gls display with a 50gls sump running for 6 months with the following equitment .
-Royal exclusive 160 skimmer.
- 2 mp40qd
- ATI hybrid led/ t5 8 bulb unit
- run carbon on a bag
-use filter socks ( change every 4- 6 days)
-1/2 inch sand bed for looks.
I perform 30gls water change weekly.
I am having a problem controlling alkalinity, for the first few months I kept it at 7.5 to 7.7 dkh and all my SPS frags were growing OK with good colors., but for the last 2 1/2 months alk got to 10.9dkh with no dosing.
I thought it was the salt bucket that I just finished at the time . Since then I started 2 new buckets and tested after mixing and both tested at 7.2dkh. But alkalinity stays at @ 10dkh.
I am not dosing anything at all.
The acro frags are looking terrible, some brown and some pale.????
The montis are OK.
Where is the increase Alk coming From?
Thank you in advance.
