Dosing Pump recommendation??

[04V10]

Hey everybody,

I am looking to automate my dosing that I am currently doing on my 20gal. I would like to get something that I could also use on a larger system when I do eventually upgrade. I was looking at the bubble magus 3 pump system, but just thought I'd see what everybody had to say.

I currently dose Mag twice a week as it stays pretty stable, however I dose alk and Ca every day. (my sps are growing like crazy currently..lol)

I am also in the process of figuring out an auto topoff system for it, however as I don't have a sump I'm trying to build something low profile. If there are any suggestions for topoff systems I would appreciate that as well.

Thanks guys!!!
