Is there a monitor for for measuring ALK. I have a Pinpoint PH and Calcium monitor. Didnt see a ALK one listed.
No alk probe available. But we all wish there was one ...
Opinions on Purigen. Good or bad.
Never used it, so no opinion
New setup, should carbon be used.
It generally takes a little while (months) for organics to accumulate to a problem level, depending your level of skimming. Can't hurt to put some in a bag in your sump (in a area receiving decent flow), but probably isn't necessary. One thing to be aware of - since carbon is porous, it is an excellent media for denitrifying bacteria. If you have carbon in your tank from day one, it could end up being the primary home for this bacteria. And when you take the bag out, you are suddenly removing a major portion of your denitrifying bacteria. I would use two bags, put the second in two weeks after the first, and then two weeks later take out the first one, and replace it with a new one. So you always have two bags of carbon in the sump, and are replacing the oldest one every month. That way you are not impacting the denitrifying bacteria population quite as much.
Rowaphos is the best but expensive. Does it regenerate, to make it worth buying.
Does not regenerate (at least not for mere mortals without access to an analytical lab, etc.). Still worth buying.
Feeding a SPSs dominant tank. What is good and what is snake piss.
Find out what your SPS corals eat. Then you can either feed what they eat, or what feeds what they eat. For example - phytoplankton is not in the direct food chain for many SPS corals.
Also, beware of anecdotal evidence without reasonable explanation. For example - various glucose-compounds can stimulate polyp extension (which looks good) without necessarily actually helping the corals.
Just a few questions for now.
