-Erm I am new in aquascaping and I do not know what is fert. Dosage regime is just follow the bottle and pour the fertilizer.
Dear Darkdevilrey,
I guess your in the wrong forum coz here is for planted tank that is for underwater plants talk only...
Since your here, let me give you some advice on your tank.
I may not be pro in planted tank but I have many years of experience with fishes.
You should DEFINITELY move to a bigger tank.
You got 2 Red Tail Barbs, 1 Clown Knife fish, 1 Pelco and 1 Patin Fish or Iridescent Shark all stuffed in a small tank.
Knife Fish and Patin can grow up to a few feet and in a matter of fact all fishes in your aquarium will grow into big fishes if the manage to survive till maturity.
Its very sad for such fishes to live in a small space. You should at least get a 4ft tank or bigger to accommodate them.
Its not surprise why your water is cloudy even you have a filter.
The tank you have now is suitable for a community tank. Its ideal for small fishes like guppy, tetra, mollies etc etc...
Get a bigger tank please. Patin loves to swim around and they eat a lot too.
Good luck with your tank bro.
