Per aquarium water column volume of 66 gallons. If it matters any, I am using MgNO3 as opposed to KNO3.Hi Immortal1
Is the added 6 ppm NO3, 2 ppm PO4 and 18 ppm K per aquarium size or per changed water quantity?

Hi Immortal1
What I meant was subtract what goes out from what went in in one week.
In:
A. ? ppm TDS (premix tested with TDS meter)
B. 15 ppm Ca (for reference only)
C. 6.5 ppm Mg (for reference only)
D. 8 ppm NO3 (per changed water)
E. 2.7 ppm PO4 (per changed water)
F. 24 ppm K (per changed water)
G. 0 ppm NH4
H. ? dKH
Out: Just before water change
A. ? ppm TDS (to monitor changes) 111ppm
B. Ca doesn’t change much in a week, maybe – 2.8 ppm, ignore
C. Mg doesn’t change much in a week, maybe – 0.7 ppm, ignore
D. ? ppm NO3, to see if fish waste produces more than plants take Salifert NO3 kit looks like 10ppm looking straight down. Looking thru the side (10x magnification) it is not 100ppm. A little darker than 50ppm so I am guessing the tank is holding around the 6ppm that I am dosing.
E. ? ppm PO4, to see if fish waste produces more than plants take API PO4 test showed 2ppm. I cut the next test with 50% RO water - result looked very close to 1ppm so I better believe the result.
F. ? ppm K, if you have a test kit I do not have a test kit for K. My dosing should add around 18ppm
G. ? ppm NH4, to see NH4 : NO3 ratio due to fish waste API Ammonia test showed 0ppm. Also tested her 40g and the RO drum - all were 0ppm
H. ? dKH, to see if something is effecting it API test kit generated color change on first drop. Suspect I am running less than 1dKH. My dosing of the RO water is intended to give me about 1dKH
The result could reveal interesting scenarios with your high light, high CO2 and high fish load. Just interesting.
Was hoping to get the water change in today but the RO system has not caught up yet (morning water change on 40g & 20g tanks). Still hoping to get the water change in before I go to bed.In:

Ok, I've been following along on this thread as I am attempting to learn as much as I can about planted tanks in every aspect.Was hoping to get the water change in today but the RO system has not caught up yet (morning water change on 40g & 20g tanks). Still hoping to get the water change in before I go to bed.
My last batch of RO measured 80ppm TDS with the CASo4, MGSO4, and K2CO3 added (CA=16ppm, MG=6.5ppm, 1dKH)

The information being shared on this thread is educational as well as interesting, albeit above my head.
I apologize, in advance, for detracting from the spirit of the thread.
What kind of RO system are you running?

That's a nice set up and I do not think it to be excessive, at all.Probably excessive ;-)
Liquagen 150 gpd 4 stage RO system. Booster pump to raise line pressure from 54psi to 93psi. 650 gph Jabeo pump in 50g plastic holding drum

When I went RO I went with the BRS water saver kit (dual RO membranes) and I produce about a 1:1 ratio with my pressure at 90psi due to a booster pump. That's a big water savings when making 120g of RO water for me. I'm half tempted to add a second booster pump and another set of dual membranes for my slow 2 day winter time production. I use the Spectra Pure 99% rejection membranes too and usually get a 0-3 TDS output.That's a nice set up and I do not think it to be excessive, at all.
Have you considered adding a second RO filter to increase the output, likely doubling it, while not affecting the water parameters? This may not be a concern as you have the holding tank but it would save you a lot of water.
I presently have my RO system set up this way because I do not have anywhere to place a permanent holding tank and being able to fill my 58g water change container in 6 hours is fantastic. Plus, I like having less waste.

Thanks Chayos00 for the info and compliment. The copper lines were a fun little addition to the setup. I very well may look into a second RO membrane as you and Reefer mentioned. Kinda getting tired of hearing the wife complain about how much water is going down the drain :grin2:When I went RO I went with the BRS water saver kit (dual RO membranes) and I produce about a 1:1 ratio with my pressure at 90psi due to a booster pump.

Love the copper hardline for the RO water!

Hi Immortal1
You have it all balanced so nicely there is nothing to say, except maybe you could do water changes every two weeks. Basically the fish feed the plants with the right amount of nitrogen and phosphorus.
You’ve got pretty happy fish over there.
Wow!Was getting ready to go do yard work, looked over at the tank and realized - hey, thats really starting to look like something. Figured I would share. Hope to do some more trimming tomorrow - several groups are getting a bit too tall
Good questions. As for clearing a spot I will probably have to leave that up to you - but I will try twisting your arm a little bit.That Rotala Bronze is a good looking plant.
What is the color like in person? Looks more pinkish than bronze? Trying to determine if I need to clear a spot for it!:grin2:
Looks like a winner!So I figured I would finally add some info on my latest hardware addition - a dosing pump. Front loading macros is not too big of a deal. Remembering to add micros 3 times per week based on what day you actually completed your water change, and for which of the 3 tanks gets to be a bit much for my absent mindedness :grin2:
After a bit of research I went with the Kamoer X1 micropump. Still need to prime it with the actual micro solution, but the pics below should give you a good idea of the progress...

Dosing schedule was 10ml, 3 times per week. Now it will be 6ml added on Monday, Tuesday, Wednesday, Thursday & Friday.
