Hi Randy,
My tank is basically LPS and softies with 2-3 sps and 2 clams. I have the largest version of deltec CR and I notice i have to crank up the CR and run 12 hours a day in order to meet the KH demand and keep the tank stable at 7dkh.
Recently I visited a LFS, and they told me that it is actually doing more harm for the tank to crank up such high calcium level since I only keep LPS. My calcium is at least 450 ppm. The excess CO2 will drive the ph in the water to very low since the kh is only 7dkh.
He actually advised me to turn down my CR (since i don't need so much calcium), but to use seachem reef builder 3 times a week to maintain the kh at 9 or 10.
Is there any long term side effect if I use seachem reef builder to maintain kh without dosing anything for calcium other than the running of the CR?
How do people maintain kh at 10-11 dkh by using CR alone? My kh demand in the tank makes it virtually impossible to do so.
Please advise.
Thanks,
Dave
