Help EI 1000mL mix

[rusky04]

Hello everyone! I've been browsing this forum for about 6 months now, ive been reading and getting a lot of good information. I've been dosing my tanks ei daily mixing single batches every morning, so I finally pulled the trigger and bought 3x 1000mL bottles from gla. I've mixed my batches this Saturday and dosed my macros (there was some un dissolved salts on the bottom of the container) Sunday I dosed my microplex and 11% DTPA FE. Today in the morning I went to add my macro and when I shook the container there was a thin layer of one if the salts that broke free from the bottle, I think I somehow messed up my measurements when I did the mix. I wanted to see if someone could help me out and look over my calculations. Thanks in advance!

Macro: 1000mL container, 15mL dose into 20long
*KNO3 - 61.72g
*K2SO4 - 84.35g
*KH2PO4 - 9.4g
*40mL glutaraldehyde 2.6%
*-960+ mL di water
( I think I have way too much K2SO4)

Micro: 1000mL container, 15mL dose into 20long
*Miller Microplex - 63.09g
*60 mL glutaraldehyde 2.6%
*-940+ mL di water
(I know there is about 163% Cu but I don't have any sensitive fish there)

Iron supplement 1000mL container, 15mL dose into 20long
*DTPA Fe 11% - 22.94g
*60mL glutaraldehyde 2.6%
*-940+ mL di water
( I think I'm way overdosing on iron )


Here are the specs of my 6 months old tank:
20long
Dual t5ho 8hrs photo period
Pressurized co2 42ppm (1 hour before lights out - kh7 , ph 6.7)
MGOPS with sand cap
Osmocote+ root tabs

I assume second item is MgSO4.7H2O ? (not potassium carbonate, but magnesium sulphate-heptahydrate) else you are not dosing EI and could explain why your salts are not dissolving.

Currently you have no Mg in your mix. If you will need to dose 255gr about 50tsp of MgSO4 if you want to dose EI as opposed to "something I made up"

Also dosing glutaraldehyde should be separate as there are reports of it reacting with salts, especially the micros, when stored in bottles.

What does your drop checker indicate as I severely doubt CO2 is 42ppm, you are being misled I bet by a kH test kit ? You can use a pH pen to measure pH drop (1 pH drop indicate 30ppm) to determine the amount of CO2 but you cannot state you have kH of 7 and read across the table to 42ppm. You will be wrong.

Iron is very rarely needed, most micros have it, I assume yours hasn't ?

The top bags are the original purchase I made for ei dosing, it also included csm+b but I desided to use miller microplex, I purchased my stuff from http://greenleafaquariums.com/aquarium-fertilizers-supplements/micro-macro-fertilizers.html

And here is miller microplex msds

MgSO4.7H2O Is Epsom salt? If so I have about 50lbs of it I could easily whip up a batch. My tap water ph is 7.8 and when my co2 turns off my aquarium oh is about 6.4 the drop checker is yellow. I also add about 5ml of straight 2.6% glut before lights turn on at 05:30

Should I get rid of my macro batch and make a new one? Get rid of K2SO4, keep KNO3 and KH2PO4 same , and use MgSO4.7H2O at 255g in 1000mL container, dose that at 15mL?

What I dont understand is why the company selling ei kit when it's not one!!

Wow all these articles claiming EI dosing, yet no magnesium as they assume the Mg present in water is enough, which it maybe in the US. Some cover themselves saying you may/might need to add magnesium sulphate ....The Miller Microplex does have magnesium, so might be OK. Magnesium isn't really a macro element, but it can be quite easy to get deficiencies, easily cured with Epsom salts.

So, I would just dose what you have, make sure you does alternate days as the phosphate will react with any iron to form insoluble iron phosphate.

In future mix again, but personally dose the glutaraldehyde separately just in case the reaction rumours are true.

Mg deficiencies are easy to spot and cure.

Today I noticed that I have a small gsa outbreak on my glass, so I decided to bump my KH2PO4 to 2ppm

I have about 828ml of my macro solution left, so I figured if I add extra 1.30gr of KH2PO4 it should put me right in the 2ppm. Hopefully it will help with my gsa outbreak.

Today I noticed on one of my Labellia Cardinalis plant leave some white, is it some deficiency?
Here is a picture, you can see the white patch there.

I guess I'll leave this here too, all of my blyxa japonica started to flower about 2 weeks ago. Seems like submersed the flowers don't last long, so I floated one of the flowering plants.

Here is a quick video that I took last week,

Looks good man!

What type of light are you running on this tank? Do you happen to know a rough par value?

 

[rusky04]

30" beamswork double bright .50 watt led fixture
45 par @ 10"
100 par @ 6"
150 par @ 4"
350 par @ 1"

Quick update on 2 tanks,

 

[Rahms]

looks great, get a journal going!

 

[jagillham]

Both tanks look amazing.

 

[rusky04]

Thank you both for the kind words! Rahms, as for keeping a journal, I don't have much spare time, this thread right here is as close to a journal as I can get. I also have few other tanks, that are not good yet, they are work in progress.
