KNO3 available

[Dodofish]

Instructions from the label

10ml of solutions to 100litres of water will give 38 ppm K and 62ppm NO3 nitrogen. This is base on 10% KNO3.

Ok thanks bro.

That is 10% concentration. However now you have to half that since its 5% concentration since 10% cannot be sold.

Terrorism cause too much problems for us. Now, we can't enjoy the good deal.

Haha. I cant agree more.

This makes us always 'half priced' but pay full price.

Still 1L could ever last before you make subsequent purchase , even they reduced to 50%. Compare to Seachem Nitrogen, best saving ever.

[Sleepy_lancs]

For a small tank yes. Not for a large tank. I feel my wallet crying!

bennyc, understatement... a lot suffer bottlenecks or bans due to terrorism...

If 10% concentration not allowed, why don't they make 9% concentration and sell at the same price. Just a thought.

Most likely the restriction dictate the percentage.

But I agree 5% still a good deal.

bro, if i am the nea people and they really do try sell lower by 1 percent after i give warning. i will think these people trying to be funny, then will become more strict and run random checks on the selling product. If more then 9% issue summon since already warning liao.

5% is better then giving hobbyist only a substitute to use, thou not powdered form But far better then non at all.

just my 50cents...

[limz_777]

is the 5% kno3 cheaper then dosing cano3 and k2so4 ?

[Sleepy_lancs]

Based on what I see it may be still cheaper to dose CANO3 and K2SO4 in the long run however, to me, dosing so much CA (where you may have to soon dose MGSO4 (not calculating the cost) to balance it) compared to KNO3 where K is required as a Macro. I use Seachem Equilibrium to provide both CA and MG in proper level. I have been down the road of too much CA so I will try to stick to KNO3 even though it maybe slightly more expensive.

Sorry, can educate noob anot? why must balance CA with MG? what are the levels then? Where to read up more? Is it link to EI dosing?

[Sleepy_lancs]

Ahh... I am the Noob here. Anyway, from what I see from my old tanks, when CA/MG becomes too high, it I seeing deficiencies of leaf curling & tip stunting. I have to keep trying to re-balance them. I used to put coral chips to allow CA to get to my tank and I get great growth for some plants (rotala, swords & APP) then left it too long and things gone bad. I believe if you are dosing CAKNO3 following the same dosage of EI for KNO3 then you should be getting somewhere around 10ppm which is still okay as long as you are doing 50% water change but do look at your plants if it's showing leaf curling or deformed, you may have to add a little MGSO4 (too much of this will block CA intake so don't go crazy over this ) to your dosage.

Ca deficiency cause distorted leaf growth
Mg overdose cause distorted leaf growth

Dosing CaNO3 will not cause distorted leaf because no Ca deficiency.

What else can causing distorted leaf? CO2, K and B deficiency. IMO for distorted leaf I would point finger to CO2 and K because these 2 are macro nutrient. The rest are micro nutrient which normally OK as long as you dose trace fert.

[barmby]

Maybe I will up my K2sO4 after reading Shadow advice! no more cupped leaf!!!!!

[illumnae]

No issues with additional Ca - excess will just remain unused and will be removed with your weekly water change per EI instructions. Purpose of this water change is to prevent excess buildup of all chemicals, including Ca. If people in the west who have very hard water (lots of Ca and carbonates in the water) don't have problems, we certainly won't just by using Ca(No3)2!

Also no issues with deficiency of Mg by dosing Ca(No3)2 since you will be dosing GH booster as per EI instructions. GH booster already contains Mg. GH booster also contains some K.

Using Ca(NO3)2 + K2SO4 (I use KCl) is more cost efficient than buying a 5% liquid of KNO3 imo.

[milk_vanilla]

Sorry for out of subject,

How do you get GH booster here in Singapore?

[illumnae]

Seachem Equilibrium or Eiho GH Booster, both quite commonly available. If you can be bothered, you can mix your own using CaSO4, MgSO4 and K2SO4. Recipe can be googled.
