Ok, I am starting to get some hair algae. My new growth seems deformed and stunted. I have tried upping the trace and then lowering it way down. I also tried adding calcium. I am still dosing the DS solution at 6ml daily and 1ml TE. Actually I went a few days with 0 TE because of the hair algae. Can you give me a little help on this please. Thanks for all you have done.

I just tested my parameters
kh=4
gh=8
Ca=25ppm
Po4=1.5
Kno3=5ppm

My Nitrate finally went down after 2 weeks of DS dosing. Why would my Po4 go up from my last test 5 days ago though?

Hi chiahead,

why are you dosing Ca? Eco should give you plenty. Good Ca is 20 - 30 ppm.
Your Mg of 20 ppm is too high. Should be 5 ppm. Do you dose any MgSO4?
Is CO2 30 - 40 ppm?
What kind of TE do you use?

Because your NO3 is down, need to stop dosing DS and go for 3ml SS Solution and 3ml PF Solution. This will add K and NO3.

I was dosing Ca for a few reasons. FIrst I was noticing that deficiency I stated and because my Ca/Mg balance was too much Mg so I thought if I dosed Ca it would help. Between the Eco and Onxy sand I should have plenty Ca, but my Gh went up from 5 to 8 in 5 days and my Ca stayed the same at 25ppm or so. I do not dose any Mg at all. My Co2 should be ok- it is about 47 or so. The Te solution I am using is your Te formula, with the CSM+B. Should I be adding the standard solution which has Phosphate in my tank when the phosphates are still too high at 1.5ppm?

Hi chiahead,

usually Eco leaks Ca and Onyx leaks Mg. You will have to flush the aquarium more often to maintain the Ca and Mg under control.
Deficiency pictures are confusing, same symptoms may be caused by number of reasons.
The 1ml of TE sounds about right.
Your PO4 is 1.5 ppm, if you want to lower it, you can dose 3ml PF and 3ml DS for a week.

Is it possible to use NH4 instead of NO3? I´ve been using a mixture similar to yours (i was low on PO4) but Amonnium sulphate instead of nitrates, NH3 is 0.2 - 0.5 ppm, fish don't seem to matter, plant growth is very good, some minor problems with green algae.

Hi ruben,

here is the answer

I went through this post several times.
I could not find any "target" here.
Edward, could you please post the target figures, which I could treat as a "Good" ones?
I would like to know the level of:
NO3
PO4
Ca
Mg
CO2
and maybe KH together with GH

otherwise it is difficult to understand where the good dosing is, at least to me.

Thank you in advance,
Andrey

Hi Andrey

Sorry for the delay in answering and I know I'm not Edward but ill take a crack at this.

NO3---- 10 to 20
PO4---- 0.5 to 1.0
Ca----- 20 to 30
Mg----- 1 to 5
CO2---- 20 to 30

Your KH is dependant on your CO2 levels and pH and your GH is a function of your Ca and Mg. You may want to take a look at the articles posted in the following link they help in explaining many of your questions and provide graphs also.
