SPS dosing

[C Dog]

For tanks that are heavy SPS what kind of automatic dosing systems do you have and what are you dosing? Looking for a cheap system. I have only used manual part 2 and fuel. I am setting up a 478 gal

That sized tank you should probably consider a reactor. I use a bubble magnus dosing pump but my tank is only getting 35ml of 2 part a day.
