Co2 inline diffuse.

Plant consist of staurogyne repens,blyxa japonica,fissdens on lava rock.

Looking at your light intensity and diffuser, I would suggest you start from EI method, and customize your best recipes, according the plant observation .

There's lot of EI calculator and kick start ingredients from google.

Hi how to i do the calculation?as im quite new to plant.tks for the advice

[Wst]

If I'm using lushgro Aqua for my 800 litre tank so I will be dosing 80ml for the tank right?so 1 weeks have to dose how many time?

[Wst]

examples if I want my N to reach 10ppm.i should do alternate dosing like 3 x a week per dosing try to reach 3ppm or one shot.quite confusing?EI mean weekly target?

Lushgro may not meant for EI, though it's still possible to achieve certain nutrients parameter for EI purposes, however it may not so cost effective and other unintended nutrients might build. You may try dry fertilizer instead or some specific liquid fertilizer (if budget is not really matter)

Hi, I use LushGro for all my planted tank. For me it is good and value for money.
As for EI methode, do a search on Tom Barr's posts on EI (estimative index) .
In short, it is a estimate dosing methode, need not to be exact amount, dose more is ok but you MUST do water change weekly 30~50% and this may be challenging for you 800L tank...
Happy aquascaping!...

I agree on this statement. Lushgro Aqua was created for PMDD methodology. This method provides supposedly 'just enough nutrients for plants'. This methodology limits phosphates (hence the reason why Lushgro Aqua does not contain phosphate) so that plants out compete algae for phosphates -> algae control.

Lushgro was not created for EI.
You can still dose sufficient Lushgro Aqua to achieve EI methodology (i.e. non nutrient limiting => excess nutrients all the time. But execute a 50% water change to 'reset' the system weekly). As what Milk_Vanilla mentioned, its not the most cost effective method.

Ideally you want to spread it out as much as you can. Best to split the weekly requirement to dose daily. If not practical, then once every 2 days is just as good.

Tks for all the advice.so that mean I can dose 3 time a weeks to achieve weekly ppm?let said I need 10ppm that mean per dose 3ppm a week 3 time?or 1 dose 10ppm 3 time a week?

Hi if im looking at dry fert any suggestion which 1 to buy?

N?
P?
K?

So which dry fert to buy ?even looking at lushgro website still confused with 1 to get

[Suzerolt]

Items in bold font are from Singapore Hydroponics website. The rest can be found in LFS.


I would get the following for the macros :

- 1L bottle KNO3 (5%) liquid (SGP law allow only 5% solution to be sold. No dry powder allowed). Buy directly from Singapore Hydroponics shop in Lavender - For K & N
- 1 bottle Potassium Dihydrogen Phosphate (KH2PO4). Get the smallest bottle because you need very little. - For P

For trace elements : Get Lushgro Micro (liquid). Or Seachem trace
For GH booster, get Seachem Equilibrium (for Calcium & Magnesium). About $8 per bottle

Ok tks for the advice shall go check it out

This EI method is so confusing. I have lushgro too and got no idea how to follow the dosing methods. I just follow the instructions on the bottles. So far I notice algae bloom fast every single week I dose. Treat it as food source for my ever hungry SAEs.

[Wst]

So what the ideas for individual ppm should I achieve for a week?

N ppm?
p ppm?
k ppm?

[Suzerolt]

I chatted with Dr Mallick & he specifically mentioned that his Lushgro Aqua series was created for the PPMD regime.
I too had algae bloom with Lushgro Aqua when attempting "EI" methodology with it. Just dial down on the amount added & your algae can be managed. From there, increase slowly.

IMO, always measure what you dose.
Know how much your take up rate for Nitrate (N) & phosphate (P) using a test kit. Not necessary to measure Potassium (K) as the test kits are quite expensive.
What i did for example : Measure on Sunday, then measure a couple of days later. From there, you know the take up rate per day.
Then dose accordingly using the excel or online calculator.

So if i want u dry fert for N i should get CaNo3+k2so4?is 2 different powder form right?how should i add in?add in directly into tank or mix this 2 power in a container then pour into tank?tks pls advice

N ppm?
p ppm?

NO3 range 10-30 ppm
K+ range 10-30 ppm
PO4 range 1-2 ppm
Fe range 0.2-0.5 ppm or higher
