Unless you are crazy over stocked, you shouldn't really be dosing as it is. Maybe look into a refugium or reactor instead of dosing. I run both and am pretty heavily stocked which is why I dose.

So for your calcium, it will stay up with consistent water changes. You are using good salt and sounds as of your water quality is also good. Your hair algae problem going away is also a good sign of this.

Dosing helps yes, but there are far more factors going for you that you are doing right. Water changes and a good skimmer as well as feeding less and less light will kill your algae problem. Starting with water changes which you seem to be doing, best thing for a tank IMO. I don't know who is telling you about dosing 2 ml a day, but that's a bit much. I have several fellow reefers who dose 5 ml slowly over a week for 300 gallon sps and Lps dominated tanks.

I know I said a lot and I hope it makes sense, but going slow on dosing is key and dosing a small amount is better. Not dosing eventually is what I hope to achieve one day.

Carbon dosing take time before bacterias develops... On my article it says we start at 0.1 ml/day, and after 5-6 weeks I should be at 2ml/day. Anyway, my algae problem is going away, coraline just start to replace the hair algae. I think I will stop dosing vodka soon.

I do 4g change / 2 weeks, my setup is a 20g. So that's 20% each two weeks. Is that too much ? Should I raise Mg ?


That's where I found infos on vodka dosing http://reefkeeping.com/issues/2008-08/nftt/

Yes building up the bacterial before dosing is good, your doing that right. Like I said, I dose a total of 3ml over a week, so 2 a day seems very high. 20% is a good volume very two weeks. As long as you are consistent it will show. The good thing about dosing is it pulls the organic phosphate out as well if you have that problem. You can't test for it, but if you have algae and you aren't over feeding, pretty much you have that. Just make sure your testing for trates when you dose. You don't wanna strip your tank clean.

Your levels should stay in the good with your water changes. Using good quality water and good salt will keep it where it needs to be and the algae down. Best thing you can do for a tank is a water change.

I can't read my NO3 or PO4 with my API test kit, it isn't enough accurate... I always get 0 and 0 in my SW tank...

PO4 always read 0 in both my 2 FW tanks... I think there may be an issue with my PO4 test kit...

API tests outside of ammonia, nitrite, and nitrate are garbage. I would suggest investing in dependable test lots, like Red Sea or Hanna checkers.

I've got RedSea for Mg,Ca,KH, thoses the most important values IMO in reef aquariums...

Correct. You stated your readings were off and figured you'd like an alternative to research the solution to what is going on in your tank.

Yeah, but I don't want to invest anymore in tests kits, especially for phosphates... Anyway, bioload is low, and I only use RODI water... I just think you convinced me to stop vodka dosing, anyways, algae problems is going out slowly overtime. It's a new setup.

I'll just dose myself with the remaining vodka instead .

Should I add a bit magnesium to the water ? Does corals or fishs or inverts don't like Mg fluctuations ?

Mg is for calcium and alk to stay stable and help corals to grow and use it. It's important but your at a good level. It should come up with more water changes. Not dosing is good, but it wouldn't cut cold turkey. Maybe stay at low amounts and only dose a few times a week then in a couple weeks, cut it to once a week.

So I should add progressively Mg until I reach 1400 overtime ?
