I am hoping people will respond in this thread. I am 90% sure I am going to make a switch to this method.

Glenn or someone else-on the DSR EZ calculator for the EZ Carbon do you just start on the D1 setting and monitor? I assume the D1 stands for day 1? I know on the full calc you input PO3 and Nitrate values, but not in the EZ.

So do you just run the amount for D1 and then check the next day to see the effect? Is it a situation where you just eventually find the current ideal D number for equilibration for the tank and then monitor for changes from then on? The other parts of the calculator seem very straightforward.

How long does it seem to take on average to get the aquariums stable after switching to this method? Glenn, I have read the entire big thread here and on other forums. Thank you for all the work you put into tinkering and fleshing this out for the hobby. And definitely thanks for the efforts to get your products into the US market. I only just revisited this topic recently as prior to the only way was to order out of country.

Thanks,
Steve

Yes start at d1 and go slow.
I ran d1 dose for 3-4 days before scaling up and did the same for each higher dose.
I checked po4 every week.
For me when the green algae on the glass turned white, i.e., bacteria, I backed off a few ml's and checked po4.
Every system is different so its hard to say how long it takes as feeding and export on each system is different.

That's sort of what I figured. I checked my levels yesterday and PO4 is 0.08 down from around 0.2 as I started running GFO again. Nitrate between 3-4. I'm sort of concerned about throwing off the PO4/NO3 ratio until I get the EZ carbon so I may stop the GFO.

I'm currently running ESV 2 part but their prices have skyrocketed since COVID and I think the DSR trace replacement is more thoroughly fleshed out. I ordered the starter pack yesterday for the EZ, but I am sure down the line I may convert to full. I also need to rework/get a new sump because I will need to run the PF in the sump and my return pump compartment won't allow the PF attachment.

So, when you say run for a few days and then decrease a few mLs do you mean you decrease by changing to the next lowest preset D number setting on the calculator, or do you adjust down by less?

Also, one thing I think is difficult is to calculate the actual volume of water in the aquarium. It becomes difficult after you add rock and then a sump. Then corals grow and displace water as well.

How do you all go about calculating your volume?

I have a 120 with 40 breeder sump.
I base all my adds on the 120 tank size. If your off a few gallons I dont think it matters much and its easier.

Example: I start at day one 1ml per 100 liters.
100 liters is 26g's. I round down to 25 for simplicity.
So thats 5ml for my 120. Thats close enough for me.
I run the 5ml a day for a week.
You can go less hence the few days, 3-4, but a week is generaly what I use.
I have learned its best to go slower when first carbon dosing.
You do not want a large and quick buildup of bacteria.
Then d2 is run at 1.2×5ml=6ml a day for a week.
This is how I slowly rampup.
The decrease is when you start to see your green algae on the front glass turning white, i.e., its bacteria.
So if after a few weeks your at say 15ml a day for reference and you see white then back down to say 10ml and test po4 and no3.
This has worked well for me no matter what carbon I am running.
I have noticed that ez carbon is strong which is good as you dont need as much as say vinegar.

Ok, this is really good information and thanks for the response. Do you run the PF in the sump or display? If the display are you just using a powerhead? I'm considering altering the method to use the main PF in the sump and then occasionally adding tossing a powerhead into the display for a couple days to supplement the sump.

How long have you been running the method and do you like it/noticed a difference?

My 120 is BB.
My frag system has sand.
I run no power filters.
I tried them on my return but its just another thing to monitor/change, imo.
I run 4 Tunze powerheads in the tank so their is no was to adapt then.
I would not want them in my main display anyway and did not see a difference on the return.
I run a 7" filter sock in my sump and it works well for me.
I am going to go to a filter roller system soon as I have seen them in action.
Mine is going to be a DIY as It is going to be manual instead of automatic.

I have ran a modified DSR since day one or 23 months now.

What is your takeaway from this method of reef keeping? How does it compare to other methods you've tried, or is this your first attempt with reefing?

Have you noticed significant increases in amount of DSR liquids you've needed to purchase? How often are you testing water?

Thanks for sharing info. I just received my shipment of starter kit but am waiting until I run through this last batch of ESV 2 part and I need to potentially reconfigure my sump. But maybe I'll just run it as it is with my filter socks.

I have been reefing since the late 80's.
This is by far the EZ'est method yet, lol.
I run a Carx.
My ez trace has been at 6ml a day for well over a year now in my 120.
My 45 frag is 3ml a day.
I do not run EZ carbon on my 45.
I am at 10ml a day on the 120.
I control EZ trace dosing, which is done by hand, by the mag level.
I test for mag maybe every 2-3 months. It is very stable.
I test alk daily because its simple and takes very little time.
I test ca every 3 months maybe, as it does not vary, if alk is stable for me at 7 dkh.

I do not run a power filter and just plugged this in and will not go back to socks on my 120.

I will be getting another for my 45.
