Which Dosing unit to buy?

I had alkalinité and calcium swings.

You probably didn't have an SPS heavy tank then. If the Ca stops for a day or two in my tank, it drops like a rock. Just last week I ran out of Ca buffer for what couldn't be more than 2-3 days. In a 120g system, my Ca went from 400 to 160. It's a pretty big deal. Stability is key and the whole point of a Doser.

In the end, like most everything, you get what you pay for.

Not entirely true especially for this hobby.it is sad to see from my end (a hobbyist and a retailer) as I get aproached by many distributors with a decent price tag on an item and the markup is amazingly high 200 to 400% from what I have seen and decide not to participate.Most of the time the manufacturers and distributors hype the product so high getting every cell in our body excited and then decide to place a $$$$ price tag on a specific item.

Well, in the end if you can buy the better product (and I don't think anybody can argue that the GHL product is in any way inferior to the other), I will. I know I've already spent thousands on livestock and more on equipment, I'm not about to cheap out $200 on a doser.
