Lush Gro dosage for Non CO2 planted tank

[anttz]

I’m still at a planning stage of setting up a second planted tank. Therefore would appreciate some advice. This time round intending to go for a non co2 planted tank. Some question I have:

The recommended dosage for Aqua is 10ml per 100litres water while Micro is one drop per 100litres water. Presuming this is with co2 injection.

For a non co2 heavily planted with 2 wpg of light, can I continue to dose Lush Gro Aqua (LGA)? If yes, as uptake by plant will be slower without co2 injection, how much LGA should I dose?

Do I still need to dose Lush Gro Micro?

Is lighting of 2 wpg (PL) too strong for a non co2 tank? Algae problem?

Many thanks.

The recommended dosage for Aqua is 10ml per 100litres water while Micro is one drop per 100litres water. Presuming this is with co2 injection.

If not changed before, I think the instructions on LGA and LGM are:

1) LGA - 1 to 5 drops per 10L of water once or twice a month
2) LGM - 1 drop per 100L of water.

So I believe they are for non-CO2 tanks. So you can use this dosing method for your low-tech setup.

Your 2 w/g seems good enough. If too strong, can always introduce floating plants.

Cheers!

Thanks KF,

I will adopt this dosing method and see how think go.

I have tried LGA only.

1 drop three times a week.
2 drops three times a week.
3 drops three times a week. (Algae starts to stain the tank walls)

for my 2 ft, or 61 litres tank, non-C02, Hygrophila polysperma-backgnd, with Sagittaria subulata as foregnd. And they are very dwarf! Nice!!

I find it best is 1-2 drops. 3 times a week.

I'm planning for H. polysperma "sunset" and/or "ceylon" as background. No idea yet on middle and foreground.

I read somewhere saying that the dosage of fertilizers must correlate to the amount of CO2.. Hence if it is an non-CO2 tank, we need to lower the dosage of fertilizers by quite a lot; considering the fact that algae bloom is still possible in a CO2-injected tank.
