Fish keep dying in my planted tank

disconnect and stop using the co2 and stop dosing ferts. Then do a 30% water change see how it goes. How often are you dosing ferts and what are you dosing?
 
KarlTH and Bro thanks. I see your points. Let me look into these issues. I did posted another earlier thread on correcting my lighting and I also need a test kit.

Will let you know if things are improving.

Neon yes I am. I had been in that nightmare and that's why I do not want to see things die any more even fish/plants. That's was the result of the cold war and Cambodia got a hot war.
 
It's a bit ashame to say how I dose the fert. I really do not have the right fert for this. What I use is an all purpose plant food. The amount I dose is not properly measured. Do have Chuck's fert calculator but I can not follow the the measure with all purpose plant food. I usually dose after water change and one or two times after say 3 times a week.

I'd forget about CO2 for now; it's not the be all and end all, although it has its uses. I'd go for upgrading the lighting first of all. Don't worry about the dosing issue; I just use a generic plant food as well. Plants which do well I prune and divide and replant; plants that die I don't use again. Even without CO2 and using standard ferts I'm a net exporter of plants to other aquarists, but my lighting is good - 140 watts over 55 gallons. Having said that, the cover glasses need replacing as they're scratched and are probably taking 25-30% of the light.

Once the lighting is good and plants are growing (and fish surviving) then you can start to tweak and improve things with CO2 and serious fertilisation and so on and so forth, but you really need a test kit to go that route.
 
I really appreciate all your helps. This is very important to beginners and I think the issues I have experienced so far plants, Lighting, Algae, CO2, planaria etc. step by step have been cleared with lots of clues from valuable AC members. I am on my way from brown to green now.
 
I hope everything works out for you
