Ok, so I'm completely frustrated with trying to figure out what I should dose for EI! After reading many forum posts I think i'm more confused than when I started. I've looked at greg watsons ferts and I have for one no idea what to order much less how much to dose. I'm definitely a beginner at this and i think my brain is having a CO2, KNLMNOP overdose! An EI for dummies page would be great!!

So here's what I have

26 gallon bowfront 2.5 wpg(65w pc) diy co2 with barr reactor
my tap water tests at 5 ppm of phosphates (I don't think i would have to dose phosphates?). I do have a tap water filter but if I am going to do a 50% water change the filter takes forever and I just don't have that much time. So if there is anyway i can avoid using it i will take that route!

What I'm really looking for is:
1. What should I order
2. Will I need any special tools other than say some measuring spoons
3. Some basic dosing suggestions such as 3 times a week dose say 1/4 tablespoon of X 2 times a week 4 pinches of Y etc.

I'm sure a can eventually get the hang of this but just trying to get my feet wet i'm a bit overwhelmed!

Thanks for any help!

For EI you dose nitrates, phosphates, potassium, CO2 or other carbon source, and traces. The least expensive way to do this is to buy from Greg Watson the following:
One pound of potassium nitrate, KNO3
One pound of mono potassium phosphate, KH2PO4
One pound of CSM+B trace mix

Then you dose these dry, using tiny measuring spoons:
For your tank size and light intensity, dose 1/4 tsp of KNO3 and 1/16 tsp of KH2PO4, 3 times a week.
Dose on the alternate days, 1/16 tsp of CSM+B, 3 times a week.
Or dose the above on alternate days, continuously.
Change about 50% of the water in the tank once a week.
You can also dose Flourish instead of CSM+B per the bottle directions.

When you first plant the tank, start dosing right away, at 1/2 the above dosages, if you wish, but don't wait for the plants to start growing.
Don't assume that the phosphate in the tap water (or the nitrates, for that matter) are sufficient for the plants. Your test kit, unless carefully calibrated by you, isn't likely to be accurate enough to believe the results.

Use CO2 injection, sufficient to get about 30 parts per milliion (ppm) in the water, best measured with a drop checker. You can use Seachem Excel instead of CO2, but it is the equivalent of a low level of CO2, not an optimum level. Because Excel also acts as an algicide to some extent, it is very desirable to have a bottle on hand at all times.

The water can be at almost any KH or GH and still grow plants ok. It occasionally happens that some water supplies are too low in either calcium or magnesium, the constituents of GH, so adding enough Seachem Equillibrium or Greg Watson's Barr GH booster, to raise the GH by a degree or two can be helpful.

Dose that help??

VaughnH,

I know for sure it helped me!! Thank you for the quick run down. I have a 50 gallon with CO2 and a lot of light and will adjust. But you explanation certainly convinced me that EI is not going to be too difficult to keep on top of.

Thank you,

Brian

That was perfect!! Thanks so much! Going to order the ferts right away.

Stupid is in town...

exactly how DO you measure out 1/16 tsp of anything???

PS as this is the only place I can post in and cannot seem to find a 'forum' link, why can I not change my avatar & why is 90% of the forum blocked to me? Wierd....

You can buy tiny little measuring spoons that go at least as small as 1/8 tsp - half of that is 1/16th tsp. The quantities of ferts don't need to be measured with great accuracy. If you want to buy a set of tiny spoons try various cooking supply stores or check on line.

You have to be a subscriber, a member, to read and post at some of the forums. That might be your problem.

I purchased my measuring spoons from AB Restaurant Supply (AB Restaurant Supply) for $4.98 + shipping. The set is called "Mini Measuring Spoon 5 piece Set Stainless Steel" in thier eBay store. The set includes the following sizes:

* Tad - 1/4 teaspoon
* Dash - 1/8 teaspoon
* Pinch - 1/16 teaspoon
* Smidgen - 1/32 teaspoon
* Drop - 1/64 teaspoon

Take a 1/4 and divide equally into 4 equal parts.
There is a 1/16th.

The forums are public to some degree, the Reports and other features/subforums are not public and are reserved for subscribers only.

Many forums have pay for added services and they also have advertizing as well.
You will note, no vendor pop up ads etc.
I do not like to deal with them.
I set this site up for planted hobbyists and to further the hobby the way I see fit, not businesses.

That makes this site more unique and it's quite a successful approach to business. Greg Watson and myself are more committed to helping hobbyists rather than cau tauing to vendors and having obnoxious ads.
Waste time and resources.

I bought my measuring spoons at Linen's and things in the kitchen dept.

Ok, so I've been dosing EI since right at christmas time. Got my co2 levels where they should be now in the 20-30 ppm range. I have to say i'm amazed by the plant growth!

I just have a few questions.

My phosphates are still testing at over 10ppm. I've been fighting green water constantly. Which i just got on top of with a uv sterilizer(wow do they ever work!) just installed last friday.

Could this be attributed to the high phosphates?


I also have noticed what seems to me a potassium deficiency. My rotala roundfolia and moneywort, on old growth, starts with a small yellowish spot which turns into a pinhole and then grows larger. So I ran across a fertilizer calculator Calculating dosages of fertilizer elements for a planted tank. When I put in my variables 1/4 teaspoon Potassium Nitrate and 1/16 teaspoon potassium sulfate i come up with somewhere in the range of 8ppm of potassium.

This seems low to me??
