3 channel vs 4 channel
 

Hey just getting into the world of dosing my tank is now exceeding the 2 week water changes and kalk ATO needs so I'm finding my self dosing alk and calcium in between changes along with vinegar, just wondering what else people use a dosing pump for and would 4 channels we needed or is 3 enough? Right now I dose vinegar alk and calcium and like once a month mag but that probably doesn't have to be on a pump

I guess there are a bunch of things people dose like alk, mag, cal, vodka, vinegar, top up water, aminos, and other additives.

As for he doser I got the Jebao DP-4 and its been working great so far. Definitely can't beat the price.

Yea that's what I was looking at too, my as well pull the trigger on the 4 channel :-)
