triton method

[beermutz123]

im have an issue in getting my alk up using the concentrated product when I first started I was able to get stuff in power and mixed and my alk was good im dosing 40 ml a day I cant seem to get it to up plus my algae is dying in my refugium

If you are adding an alkalinity supplement and your alk is not rising then you simply arent dosing enough..
That may be because your solution is too weak or you just aren't adding enough..
Can you give us detailed information about what you are using?

Are you monitoring magnesium too?
What about calcium?


If your algae is dying then there may not be enough nutrients in the water or your light isnt right.. Again detailed information would be helpful.

Post all of your known parameter measurements so we have those details.

How big is the tank? Are you seeing any signs of precipitation, like white or tan buildup on tank walls, etc? What supplement are you using?

[beermutz123]

I'm using the triton method on the tank the tank is 125 gal starting point of dosing is only 15ML a day I'm up to 40ML In the refugium im using a kessel 360

I see. I suspect you just need to add more supplement. A tank that size might need 100 ml per day or more, as far as I can tell from the supplement description. This calculator will help with picking a dose:

I was guessing that the tank has about 80 g of actual water volume, but I could be off quite a bit. The ESV entry probably is close enough for the first guess at a dose.

Regarding the chaeto not growing in the sump after converting to the triton method, do most people experience that loss of growing using this method?

[bertoni]

I am not sure. I haven't seen enough reports on Triton tanks. If the system includes an organic carbon source, it might easily have that effect.

[ThRoewer]

As I understand it, there is no carbon dosing with the Triton method. Nitrate and phosphate reduction is supposed to be done primarily via uptake by algae like Chaetomorpha or Caulerpa.
If the algae don't grow phosphate and nitrate might be out of balance or other essential growth factors like iron or iodine may be depleted.
It might be time to send in a water sample for testing to see what is off.
The light might also be a problem, if not now then long term: for an algae refugium the Kessil H380 would be more appropriate.
