Is Atman 3335 too strong for plant tank?

[Samuel Lee]

Hi,I had to downgrade my Atman 3338 to 3335 which has a flow rate of 600liters/hr is that still too strong for plant? My plants like the amazon sword plant(Echindorus bleheri) and Dwarf Ambulia(limnophila Sessiliflora) is turning yellowish but my red tiger lotus(Nymphea lotus runra) is doing well, I got a C02 supply going at 1 bubble per 4sec with ceramic diffuser and 2x36watt PL lights with weekly liquid fert.

I would actually go lower... to about 100 to 180 l/hr for a 60l tank.

You can use the methods suggested in your previous post to reduce the current in your tank. As long as the plants are not being whipped around and the fishes don't have to swim strenuously all the time.

As for your yellow plants, which fert are you using? Any base or substrate fert? Any fishes?

Hi Viz, I an using JBL base Fert and ocean free root monster and weekly 1/2cap Flora liquid fert for my plants and as the rain tube i tried the method on of the forumer suggest in my last posting it is doing fine.

Hmmm... fert looks ok. The Amazon might just be converting from emersed to submersed mode. Not sure about the L. sessiliflora.

What's the contents listed on the Flora fert? You might want to ask the forum what CO2 bubble rate their using for tanks same sized as yours.

Check this chart to see if you can figure out what your plants are lacking.

I'm suspecting either CO2 or Potassium (K).

Hi, ya I think my KH level is low and Ph is at 6.8 and i got another problem of nitrite level and had just change 50% water as I find some rotting plants that produce foul smell.
