Doser Help Needed (set-up)

Magnesium both helps to buffer the pH from falling, and reduces the precipitation of calcium. Think of magnesium as the fulcrum of a teeter totter. Without magnesium at the level it should be, it is difficult to keep calcium and alkalinity at a steady and proper level. Natural seawater generally contains 1280 ppm of magnesium. Low magnesium can be one of the factors of nuisance algae growth, and most reef keepers agree that 1350 ppm works best in our little glass boxes. I prefer to dose magnesium to ~1350 ppm before adjusting calcium and alkalinity.

Good to know. I will keep that in mind once I get my alk up.

Many people say roughly triple you calcium also. This usually ends up around 1300-1350 anyways.

One thing to keep in mind also, is that you may have trouble getting your kh up if your mg is too low. If your mg is extremely low, than anything you add to boost your kh may very well precipitate out right away.

Where did you put the check valves?

OK... so going to set this up, tonight. Late tonight.

My instructions never indicated how to hook up the tubes or check valves.

Any advice?

[rhody605]

I have my check valves just above my bottles.

Oh and tip: wet the tips of the check valves and connectors then slip them right into the hoses.

I didnt have very much hose left over after hoses were setup for 2 bottles.
Plan your hose lengths ahead of time. My total setup was about 30 mins.

So it's just to stop siphon to the tank or from the tank?

Yes, it hardly has enough hose. I definitely need more.
