Total hardness = 7 dGH (German degrees of total hardness)
Alkalinity = 4 dKH (German degrees of carbonate hardness)
Conductivity= 380 µS/cm (micro Siemens per centimeter)
Potassium= 39.2 mg/l
Calcium = 35.2 mg/l
Magnesium= 9.3 mg/l
Sodium= 0 mg/l
Bicarbonates = 87.8 mg/l
Sulphur= 30.6 mg/l (Sulfates= 91.8 mg/l)
Chlorides= 6.2 mg/l
the salts I use to prepare water

Hi
The plants look healthy....you need to cut back on the lighting intensity and photoperiod use 6 hours!
Use the Buce Light setting for 2 months and use this Tutorial below!
Remove as much algae as possible manually and increase water changes 1 per week 25%.
Do not dose fertilizers for 4 weeks.
The algae you were battling previously....was Spirogyra and others?

Using stem plants as a filtering aid at Start Up!
The subject of using fast-growing stem plants as part of a filtering aid has cropped up a few times recently. This idea has been around for a long time so not new, it has benefits especially for a new set - up. I try and cover at least 50% of the water surface minimum. 1. Improves water...

No adjustments needed!
Hi all,
You can just add a very small volume <"of tap water">, I'd aim for~ 50 microS when your water is "remineralised". Then add your fertiliser and see what conductivity value you get. That is your datum value, and, assuming plant growth is acceptable, you need your water to remain somewhere in that ball-park.
I'd also suggest not putting too much reliance on the test kit results. I honestly think that all the testing paraphernalia and "remineralising salts" are just obscuring the way forward. If you like they are all <"froth">, and all they are doing is transferring your money to somebody else. <"I like conductivity meters"> because they are plug and play.

You are <"remineralising your tank"> to a <"much greater level than you need">.

Good evening, so I did as I was advised, but I honestly didn't understand 😅. I took 5 liters of osmosis water, I removed a little and added the rest from the house tap and I got 55 micro siemens. Then I added 2 ml of fertilizer, I measured 147 micro siemens in 5 liters of water. Which if I understand correctly corresponds to the weekly water change

Hi all,
If it is? As you change water with your "new" 150 microS mix and that value should decline.

That would be the sort of level you are looking for for your datum value in the tank, somewhere around 150 microS. You just need to watch plant growth (as long as that is OK), if the conductivity value keeps creeping up, change a little more water (just with RO water) or add a little less tap to the five litres.
Is that with the water that was already present in the tank?
