Triton recommends Tropic Marine reef salt for their method, which alkalinity with that salt has a alkalinity of 7dkh out of the box. Not sure what salt you are using or what you want your alkalinity at, but Triton recommends the alkalinity to be at 7dkh. I've never had a problem keeping that. You stated it gets pricey, not sure what you mean by that. Since starting the Triton method I've been all in, have not done a water change in over a year now and my salinity has not dropped in that time. Saving the time and money with water changes are huge, not to mention the amount I've saved on filters for my rodi system. I have 2 separate tanks on this method, main tank with sump is approximately 135 gal and my frag tank with sump is approximately 75 gal. I always hear people such as yourself talking about how much it costs, so I figured out what I spent to run my systems on the Triton method. Here is my breakdown for my two tanks running the Triton Method at 100%.
I figured out cost of trace elements per ml. (for example: 1,000ml Bromine is $45 = 0.045¢ per ml or 100ml Nickel is $32 = 0.32¢ per ml) dosing every element on their list rated from 5 to 1 stars, costs $87.50 for the one test every 3 months. Figuring weekly dosing the same way, which come to $1.78 x 3months= $21.36. I go through one bulk kit of Triton Core7 in 9 months, kit $147÷3= $49 for 3 months worth. I get the 6pk of Triton test kit for $270÷6= $45 every 3 months. Triton Carbon, I get the largest one from BRS for $95. I switch out 2 media bags in my main tank and 1 canister reactor in my frag tank every 2 to 4 weeks using a whole box up in a 3 month period. I replace RowaPhos out every 2 weeks, both run in a reactor, RowaPhos costs me $162 for 3 months.
Both Tanks:
Main dosing $87.50
Weekly dosing $21.36
Triton Core7 $49.00
Test kit $45.00
Triton Carbon $95.00
RowaPhos $162
For me to run the Triton method for 3 month my total cost is $459.86 plus tax (here is $0.056) = a Grand Total for 3 months to $485.62.
$161.87 per month to run the Triton Method at 100%, not to lose fish or chicken, saving money on salt, while providing my pets with the best available environment possible (priceless). Most reefers will probably spend $50 a month trying to replace a fish or coral in a month that is not on the Triton method. Then another $50 on salt, that does water changes every 2 weeks,⁵ hoping their water is being filtered the same each water change, which is impossible on a molecule level. With every water change, the water in the tank changes slightly each and every time. Not sure what other dosing methods cost or what the cost difference might be for the rodi filters. The Triton Method is also the only method out, that has a 100% success rate, since 1986. That is a pretty good track recorded.
