hello to everybody,
i am thinking about automatic aquarium fertilization. I need two pumps, one for microelements, other for the macro. I am fertilizing my 126l aquarium one time in every day. Found several fabric-made solutions, like here:
http://saltaquarium.about.com/cs/doserstosupplies/gr/aaprliquidoser1.htm . This variant has one pump, so i need two minimum. And reseivor for fertilizers is small. Tis seems better for me: http://www.bulkreefsupply.com/store/bubble-magus-dosing-pump-bm-t01.html .
And i found diy version: http://expanser.wordpress.com/ . This fersion has 3 channels and seems quite cheap, pumps can be bought at ebay. I have electronics knowledge, so it would be not very har to do this system. It is cheapest option. So can somebody to share opinion which version better to choose?

Goes to 11!

Out of your list, I would say the one by bubble magnus is the better option.

I only have actual experience using the one in the below link. Works great for my reef tanks. I bought the 3 pump version but I can also purchase and install a fourth pump very easy should I even need another one. Very easy to program all the settings as well.

Ok, and how about noise, these pumps is noisy or not? It is actual to me, because my aquarium is in room where i am sleeping.

I have the three pumps on my dosing unit set-up to dose at different times. Basically, around every 3 hours one of the pumps will cut in for between 5 to 10 seconds. They do not run constantly. They only make a small humming sounds when they cut in. I can only speak to the one brand I linked above
