EI Dosing Questions

After experiencing some melting algae issues due to lack of flow, too much lighting, and uneven CO2 distribution, I am going to start EI dosing my tank with ferts.

This is my first high tech plant and am a newbie in the hobby. I made adjustments to my flow (purchased lily pipes that provide agitation and a nice current to all parts of the tank), lighting (reduced number of hours to 8), and repositioned my diffuser and increased CO2 concentration until I could see bubbles everywhere. I'm hoping this helps.

However, I want to start dosing as well.

Is it a good idea to dose this early? The tank is about 2 weeks old and has Amazonia. I've been doing water changes frequently (although not every day) and the ammonia levels are at a steady 1 ppm or so. FYI, no fish right now either.

When I dose, is it best to dose in the morning or at night? I leave at 8am and come home at 7pm. The lights and CO2 are on from around 4pm to 12am.

What do I do if I miss a day?

What happens if I don't do a water change?

Do I really need ferts with Amazonia?

I bought the GLA package. Is Plantex CSM + B the micro? Is Potassium Nitrate (KNO3), Mono Potassium Phosphate (KH2PO4), and Potassium Sulfate (K2SO4) the macro?

Sure, if you're going with EI there's no time like the present to get started. You're doing regular large water changes so there should be no concern about any build up of nutrients.

When I dose, is it best to dose in the morning or at night? I leave at 8am and come home at 7pm. The lights and CO2 are on from around 4pm to 12am.

I would do it when I came home. It's not going to matter with macros although I think there could be some issue with how long some chelated micros are available, but don't quote me on that, lol, so I would dose those during lights on. Just one example of how it's best to check out what people like me tell you on a forum .

What do I do if I miss a day?

Dose the next day or don't worry about it. It's EI.


What happens if I don't do a water change?

One water change I'd not worry about it too much. I would probably cut my dosing by half or so until the following change or not worry about it and dose as usual. It depends on your tank. A bunch of fast growing stems I would probably continue with full amounts. Slower epiphytes, etc. I would go with less, but with just slower growing plants and presumably lower light I'd probably be dosing a bit less than standard EI, although that's my current setup and I'm dosing pretty much standard EI amounts.

Do I really need ferts with Amazonia?

Sooner or later even if you follow ADA's dosing. They make supplements for plants that require more than Amazonia can provide and eventually it's going to exhaust itself and more quickly if you don't dose the water column.

I bought the GLA package. Is Plantex CSM + B the micro? Is Potassium Nitrate (KNO3), Mono Potassium Phosphate (KH2PO4), and Potassium Sulfate (K2SO4) the macro?
Yes and yes.

The key word in EI is estimative. The standard doses are good starting points and none of it is written in stone. If you need less, add less. If you need more, add more. Nothing is written in stone. If you want less frequent water changes then you can add less. Lighting is what will drive demand. Less light means less demand, slower growth, less algae issues and generally an easier tank. Moderate lighting and good CO2 make for an easier tank. You don't need a lot of light. That's something you can play with after learning how to successfully grow plants.

Another thing is to develop scaping skills. Not that I have any, but there's a lot of time and talk on the forum about best filter, best CO2, best ferts, best tech etc., but not enough on how to scape. Learn to grow plants then focus on scaping. Other sights such as UKAPS.org can be helpful with that area.
