IMO = In my opinion.What do these mean? imo, wcs, s.g?
How can I lower Alk safely?
WCS = water changes
SG = specific gravity ( salinity )
To lower alk .
besides salt what are you putting in the tank ?
Are you dosing or adding any additives ?
alkalinity that high is really bad .
but as I mentioned in your other post . Being so new of a system and not starting a nitrogen cycle yet . These numbers are going to be all over .
nothing will be stable .
that being said if you have added nitrifying bacteria as suggested . That could contribute to alk being off .
there is a relation between high alkalinity and nitrogen cycle but I can’t think exactly .
