Dosing Pump Questions
 

Considering switching to a 3 pump dosing pump.
Was thinking ghl standalone. Easy to use and set up?
Is it a lot of up keep to keep the solutions full?
Whats with the bailing chambers?
What do you use for your media solutions.
Thanks

Why would a person go with a 4 pump option?

Thinking Calcium, Alk, Mag. What else?

I use the SA3 stand alone Profilux. It's a joke to program and set up. Tell it how many times a day and how many ml's and your done! I just topped up my jugs after 4 to 5 weeks using BRS 2 part. I highly recommend the unit.

Love my SA3.

Very easy to setup. I use BRS chemicals in the plain 1 gallon jugs BRS also sells. Keeping them topped up depends more on your consumption I'd say. Right now I only use 8mL of Ca and 12mL of Alk per day. I only need to adjust Mg for new water and barely ever have to add it to the display. Currently I don't use the 3rd channel.

Vodka!

Depends on how big your reservoir tanks are and what your demand is. I'd expect on a larger system to have to refill every 1 ~3 months for Ca and Alk.

I use fauna mRin salts but will be switching to BRS soon.

How big is your tank? 8ml of Ca? I dose 14ml 12 times a day!

system is about 110g but I only have tiny sticks right now =)

They might be higher and more balanced if I didn't do 10g water changes weekly with a salt that is high in both but especially in Ca.

Wow thanks i will look into a unit setting it up on a friends tank but if i like it i may scrap the reactor. Better control of the levels this way.

Any maintenance with the unit that one should be aware of.

You could always buy the SA3 now and add a fourth pump down the road if you find you have a use for it. About 100 bucks for the add on pumps. And yes they are great units, very easy to set up.

Only thing I've seen that may be a concern (and would be regardless of type of doser I imagine) is that one of the solutions is sorta precipitating at the end of the tubing. Forms sort of a shell so I clean it with a toothpick every couple days. Anyone else see this? I spread my 8 and 12 mL doses into 1mL increments so maybe it's so little that it does this.
