Hello,

I plan to get PO4 and NO3 from Dr Mallick.

How much does it cost and also, what is the quantity?

If I remembered correctly, I was told it only comes in 1KG packets and cost abt $7 ?

Tks

Hi Eggs

Unless you know EXACTLY what you are dosing.......dont play with fire

Currently dosing Fe+trace elements, Potassium Sulfate and Magnesium Sulfate.

Did some reading and found out that I need to dose PO4 as well.

Fish waste will release NO3 into the water right?

Can buy a litre of LushGrow-Aqua for me? maybe can arrange a meeting.. I pass you $$$ & maybe some of my pruning can?

Hi Eggs

If you have a healthy amount of fish load, I dont think you have a NO3 problem...unless you are using too much K in the tank causing your plants to increase the uptake of NO3....this may lead you to a Ca problem and not so much an Mg....

If you must increase you NO3, then would it not be better to switch your K2SO4 to a KNO3?....or perhaps purchase CaNO3 instead?.....I dont think playing with PO4 is a good idea unless you can find a way to inject it into the substrate point blank to which ever plants needs it...if you dont know what you are doing with the PO4....KAAABBBBBOOOMMMMMMM....BBA infestation.....just my thoughts that's all

My 2 cents.

It can take quite a while to find that (level of) healthy fishload.

In a non-planted tank, having 20 fishes (pencilfishes, rams and guppies) in a 2ft tank with just an internal filter would be stretching it, esp. if I only change water every 2 weeks.

However, I had a serious NO3 and PO4 problem for my planted tank (2ft, 20 fishes, internal filter) a while ago, after I started dosing K. I now have 30 fishes and I still need to dose PO4 twice a week to stop it from dropping to 0ppm. Not adding anymore fishes 'cos my NO3 is around 20ppm.

Me too. I only started playing with PO4 in recent months.
I found that if you have PO4 levels at 1.0ppm or more, you may not want to add some more. If you have levels like 0.25 or 0.5 ppm, you can try to increase it to 1.0ppm.

For one of my tanks, I add PO4 at 0.5ppm twice a week as I found the level drop to 0.25 or 0.5ppm.

Of course, there are folks who add PO4 to even higher levels.
