My doser came in today =)

[Baldy]

ive been using a marine magic doser for around 2 years now. it has worked awesome for me. just a heads up, extra internal tubing for the pump is definately a good thing to get. the other weekend i noticed my alk starting to drop and noticed that the doser had plugged off and was wearing on the tubing for a while now. no biggie as the replacement pumps are $13, but i wish i had some spare tubing to replace it with.

for the money, its well worth it.

Here's info that was posted in a thread I had on dosing. You need to know how much of ca, mag and alk you are going through in a day/week in order to properly dose. So before doing anything, test over the next few days and see where things are at. Great advise below!

Have you figured out how much to dose to maintain your water parameters? Pick any time of day and do your water tests for all 3 (CAL, ALK and Magnesium). Go on the bulkreefsupply website and use their calculator to find out what you need to dose to raise your parameters back to normal levels. Dose your tank manually.

Now the next day do another test at the same time as the day before. Whatever the difference is, that will be your maintenance dose. Then depending on what is low (most likely ALK), increase it in equal parts. If you need to dose 15ML to raise the ALK up 1 dKH then make sure you dose the same amount for CAL. In the morning dose Calcium and in the evening Dose Alkalinity.

Keep at that pace for the next 3 days and then do another water check at that same time. Once the test results confirmed that your water parameters are that level that you want, it should be stable. Then setup your auto doser according to what you have it set for.

Every two weeks, do another water test and adjust your maintenance dose accordingly. If you do large water changes of 20% or more, your ALK will raise accordingly. This could STN or RTN some of your SPS corals. So my advice is to keep your ALK at a higher level not at 7 dKH.

If you already keep params up by say dosing 4 cap fulls of purple up then you know roughly you use 20ml per week so you dose 20 ml spread over 7 days.

I dose anywhere from 180 to 200 ml per day of cal so I spread it out over 20x in a 12hr period, my alk and mg dosed at the same time frame but on the next 12 hr period.

So this is my dosing chart:
10am-10pm Ca 180ml
12am-8am Alk 160ml
11pm-8am Mg 170ml

And as the OP said test every 3 days to make sure everything is bang on for first week, if it is test weekly then BI weekly and so forth.....

I normally just put in 1 cap of purple up whenever I remember to like once every week. What is the optimum cal and alk I should keep in order for best sps growth?

Which seller did you use? I would like to get a back up motor as I have all ready went through my first one about a year ago. Has worked great ever since but it is good to have a back up.
