Don't forget that some magnesium supplements are magnesium chloride, which can drive your salinity levels up
Just to clarify, when I suggested dosing morning and evening, I meant to take that day's worth of additive and divide it evenly, dosing half in the morning and half at night. That way you are dosing gradually and never too much per session.

I guess that is what happens when you take things for granted and don't actually test. Wish I was testing sooner. I don't have much experience with Magnesium test kits but the Elos test kit was simple and straight forward. The color changes where distinct and I am very pleased with it.

What's happening is your coralline and Montipora sp. suffer growth and color because the numbers are so low. I've never seen ill effects from dosing Magnesium heavily and quickly. I dose it into the sump's skimmer section so it has time to mix up before it makes it back into the display. For safety's sake, why not dose morning and night each day until you get it up to 1350 - 1400ppm. I prefer 1400 for my reef. 1380ppm is the lowest I'll let it get down to. I'm just worried that the directions specifically state that if you Magnesium level test lower then 1280ppm that the maximum dosage should be no more then 10ml per 20 gallons of water. That being the case I actually sent an Email over to Brightwell Aquatics to ensure that my calculations are correct and also to inquire why I cannot dose more then 25 ml per day with my water volume. Is is a solubility issue? I'm not sure but I would like to play it safe. I'm going to test again this even before I dose to see if everything is proceeding as I think it should. Sometimes I wish I would have just bought a house sooner so I could get a bigger aquarium. All in due time I guess.

For GFO, you should definitely use the sponges. They protect your fish and corals from harm from the fines that come off the media. I don't know anyone that has run without them - seems like a dangerous method to me.

Originally Posted by baker.shawn how many times can you regenerate this media? looks like a real money saver compaired to GFO, the particle size is so small id be scared of loosing half of it before it comes time to regenerate The regeneration process requires a separate media called RegeneratePhor which is not expensive at all (about $9.00 for 1,500ml of it). I have about 175ml currently and that amount will regenerate the media up to 8 times. I don't think you can go wrong with that. Also I wouldn't be worried about the small size because I have used GFO before and this media once in water appears pretty heavy. I have actually had to increase the water flow to get the boiling water affect going. My only issue it that it is so small it fell through the reactor plate a bit and collected on the very bottom of the reactor which is more annoying then detrimental in my opinion.

I had some cyano, brown stuff that bugged me, and some dinoflagellates. My tank too was new and it bugged me. I just cleaned out what I could to keep it under control. I dosed with Chemi-Clean twice in my frag tank (10g) but never the main system. I used Peroxide (3%) for 8 days twice in the 400g. And I did quite a bit of sand stirring with a Kent Scraper to get that brown dust water-borne. Algae-phases are part of new tanks no matter how you set them up.
I was getting a lot of cyano within the display tank which I have read and also heard from other members regarding their experiences as well. I guess its not something I should use when just starting the aquarium but I am going to take it back to basics for a while and slowly change things around. First I have to deal with my lighting issue.
id also like to know, i have had nothing but good results with the exception of having ultra low nutes and loosing color, but that is because my tank has hardly no fish (bio load) and i feed 3 times a week
What was the specific problem you were fighting that made you opt to remove the biopellets?
