EI dosing with Excel

I bought EI premix from Nilocog and put about 9 O+ caps in the substrate (eco complete on top of inert sand). As I am finally about to run out of Flourish comp and don't have my Co2 reg yet, I'm planning on dosing EI with Excel.

From what I have read, a 1/4 of regular dose EI, once a week, with double Excel daily is the way to go until I acquire proper gas. What do you guys think about dosing EI with Excel in a high light situation? Any advice? I will have my proper Co2 going in about 2 weeks. If my bow front was considered heavily planted, I'd say that the 40b is lightly to medium planted. Mainly Anubias, Hygro, Crypt sp. Gecko, Amazon Sword, Red Melon Sword. These are in just to make the Krib parents more comfortable and I plan on introducing different plants for a high tech tank once they are moved..but I'd hate to kill the plants I have in there now by not dosing correctly with my temporary setup.

It was all in haste but I'm trying to save my fish AND plants with what I have until I get paid again.

Thanks for any help, suggestions or advice about any of this. Thank you for reading, and ANY comment offered.

TLDR? What are your thoughts on high light/EI/Excel?

Revisiting? Yea, high light dies NOT work with liquid carbon and EI style dosing. Green spot and bba took OVER within 2 months.

Go GAS.. lifetime investment for one upfront build cost.

Excel will help but if you have high light and no CO2 algae will most likely be a problem. Raise the light if needed until you have CO2 up and running. I would certainly use Excel if that was an option until CO2 is available. The EI dose sounds fine to me.

Thanks Zorfox. I'm going to hang the light or at least put some material to break up the par a bit. For some reason I didn't think about that.

I thought that Excel wouldn't cut it but had to ask. I figure that I would reach overdose levels before actually providing enough to compensate for no gas?

Good to know the EI dose looks good. I'll just go to medium light with EI/Excel until I get a regulator.
Thanks for your advice!

If you have any Vals or Anacharis you might not want to double dose Excel at first. Excel can cause these plants to melt. There are a few other plants that can be effected by Excel but can't think of them right now.

You can acclimate these plants to Excel dosing but you have to slowly work up to higher doses. At least that's been my experience with them .. YMMV

Amano, myself, Oliver Knott, Karen Randall, we all tell folks to use moderate to lower light.

People do not listen.

If you are able to manage things well, then consider high light if you feel the need. But it's more work.

and CO2.........

Excel should not use high light, because you only add high light because you want faster rates of growth. More CO2/more= nboth mean you want faster growth.

High light and no CO2 gas, even if it's excel, is not a logical management approach. Use less light or get CO2.

Thanks SowNreap: I don't have them but did learn that the hard way in another tank.

Thanks for your advice Tom. I have raised the light a substantial amount and have decided to just go medium light, Flourish, and excel for now.

One I get a regulator I may slowly lower my light, begin using EI method ferts, and go from there. I do enjoy seeing my plants grow fast but I don't want to make it more trouble than I need. Medium light with co2 is the way I will go then. Thanks!
