What are you adding to your tank?

[daniella3d]

So far I have not had to adjust anything after the initial adjustment and it's been 4 months maybe more (lost track). So far it's been very reliable and my levels stay exactly what they should.

It cost me 175$ can shipped and it took about a week before I got it from China. They have put "gift" and value of 50$ so I had no duty to pay on it, that was nice too. no taxes and no duty...175$ shipped to my door.

The motor and pump are cheap to replace if they broke.

The only negative feedback that I can give at this point is that each pump has a slightly different output, so not because one pump does 100ml at speed level 2 for 30 seconds, it does not mean that they will all do that. Some have a slightly different debit then others so they all need to be adjusted separatly. As exemple, of you want to dose 100ml of calcium and alkalinity, you cannot assume that both pump will produce the same quantity at the same setting, there is a slight difference. However once each pump is adjusted to produce 100ml per day, it will pretty much stick to this and be reliable. I tested mine each day for a week to make sure it would produce the right quantity.

Other negative is that if there is a power outage, it does not resume on its own and you must re enter the date and put it into auto mode. However you don't need to re enter all the settings for the pumps as this is kept into a flash memory, so only the date must be re-enter when there is power outage.

That's about it.. I am happy and I only test once a week or once every second week and my parameters are always spot on and it did not cost a lot.

For someone on a low budget, this is a very nice unit.

We sell the GHL Dosing Unit, the best, most complete, most reliable unit on the market but not everyone has $400 to shell out on a doser.

It would be nice if we can carry an alternative unit that costs less.

thanks,

Laurie,
Wow, I am surprised that you don't dose at all and yet, your tanks are beautiful. When is the next tank tour? I wanna go over to see your tanks again
Reef Supplies,
Thanks for the suggestion. I will definitely keep them in mind when I make my order. I just purchased a Marine magic dosing pump too for $160. That's why I am thinking of purchasing the Brightwell 2 parts dosing to take advantage of the pump.

Thank you all for the replies. You guys are great!!

i dose nothing and virtually never do water changes on my cube 29G bc (drip lines for new stock top up) have 2 lps 1 geneopora 1 4" clam and tonnes of zoas.

I guess your zoanthids must be really happy because they react strongly to any sudden change in alkalinity...a very slow drop won't affect them as a suddent increase.

But what about that clam? I guess it does not have much calcium to grow its shell...

I dose Calcium chloride, baked baking soda , and magFlake
All bought in bulk chemical form as its MUCH MUCH cheeper
Cal /alk is dosed via doser mag is done manually usually 4-6 weeks my tank will need 50 -100 ppm
