If you are getting into SPS now, I highly suggest switching to a more balanced 2 part dosing system like BRS 2 part, Reef Supplies 2 part or B-Ionic. http://www.reefsupplies.ca/online-store/2-Part-Dosing/ Something along those lines. I don't know what the concentration is of the Purple Up or Seachem products.

You can safely increase Cal by 100 and ALK by 1 Dkh in the span of 24hrs. Don't try to do it in one shot though as it can potentially cause issues. Everytime you dose ALK, you will also increase your ph levels so it is best to dose ALK during lights off when ph is at its lowest point.

To figure out what your tank is using, you need to test once. Record your results and then test again at the same time the following day or 3 days even if you want more accurate results and then just divide by 3 and that is your daily consumption. Then use the BRS calculator and figure out how much you need to dose everyday. There will be a lot of testing for the first week or so and tweaks until you get it just right.

Gonna be picking up some soda ash and calcium
Chloride from KpG007 soon. Hope that will be better since purple up has to be shaken up real good before each use and that's not really practical for dosing. Still don't understand why adding the alk n cal didn't show a difference in yesterday's testing. Cal dropped 30pm by today. Is that normal?

What's your Mag reading ?

If it's low (below 1280 I think) you'll have issues trying to get the other 2 up

Dunno I don't have a kit for it so I never added test or added mag since day one lol

Sounds like it's time for you to make a trip to J&L and get a Salifert Magnesium test kit :wink::smile:

i guess i should lol. Man one of my birdnest is now fully bleached but the birdnest next to it is perfectly fine. A couple more acros have some bleached tip and some have rtn on the tips tho... is it cuz im dosing 250ml of the alk a day? But my kh is still under 7

A cup of alk per day sounds like a lot to me (could be mistaken). How big is your system again?

75. It's 250ml solution. Which is just half teaspoon of seachems reef builder alk

Maybe you're not dosing enough, but check your Mag before you get too carried away with the alk and ca levels

In my 110g total system I'm using 1tsp each of reef builder and advantage calcium daily (give or take), and I'm also dosing magnesium

Below 1280 is considered low? :surprise:
