Can I ask approximately how much it cost per month for a 75G tank with full blown zeo dosing?
Full zeovit = a reactor to pump the zeolite media, I had a custom out of sump reactor built by I-tech for around $200.
Zeolites= around $14 for each 1 liter bag, enough for each media change, depending on your nutrient load changed every 4-6 weeks.
Zeofood7= around $40
Zeobak= around $18-20 small bottle
Zeostart2= around $40-50
Zeo Carbon= around $15 each 1 liter bag, enough for 2-3 exchanges
That is your Basic 4... Estimated around $350-400... to get you started...
I think it should be basic 5, you need to have a way to keep up on your K, the bottle costs roughly $40-50... You also should test with a reliable K test, add another $50 to the equation.
you are now at roughly $450-600
After you are satisfied with running the true zeo ULNS, think of zeolite exchanges and carbon exchanges, and have a stock pile of those, so add another $100 to cover your 4-6 month supply.
Then,
You get to B Balance, CV, SP, AAHC, CS, ZZ, PE, and so forth adding about another $40-50 each bottle...
Can be expensive, but supps go a long way, not much needed once you get involved, but be prepared for $$$ to run the system Full Blown. I think how much $ I waste on other supps running non-zeo, and to me it makes sense, however it can be an expense to get going...
