Tank with Flourish Excel

[milesteg]

Which light intensity I could go with if I used only glutaraldehyde for plants fertilisation (in non-CO2 enrichment tank)?

 

[mr. luke]

What size abd depth is the aquarium?

 

[milesteg]

110 liters. 70cmx35cmx45cm.

Watts per gallon is what intrigues me (or watts per liter)

Par should intrigue you more personally I would use two t5s the length of the tank and suspend them somehow to adjust the intensity.

 

[milesteg]

Well, par is kinda outside of my budget/technical possibilities That's why I operate with Watts

What "s" means in t5s?

 

[tim]

Plenty of par charts you can use on the net google aquarium par chat or search it on here, "s" means plural as in more than one, as in two.

glutaraldehyde for plants fertilisation

I guess you know you have to still add ferts, glutaraldehyde is only a source for carbon (C).
Personally i would not like to add it long time as carbonsupply, i would always be scared of toxic effects in the long run, but that's just me.

Can such tank (without CO2) be maintained with fertilization method EI along with huge water changes each week?
