Hi, I have learned a lot from reading these post,and here is my first post / question. I have a 20 long tank with 12 pots of 6 speceies the water is just above the soil.I would like to know about powerheads,is one necessary in such a setup? And humidity,do I need to measure it and if so what should it be? here is a pic.



The top is usually covered, this is an 8 month old set up.

Don't fix what aint broken. Looks like whatever you're doing works fine.

How much lighting are you giving them?

Thanks for the replys.
They get 12 hrs. from a compact flood light,and is close to a window to get some sun light,amount of sun would depend on the season.

Have you had any blooms?

h2ogardener

No,not yet.I am thinking of using a bloom fertilizer,I now use 20-20-20 when I change water every 2 to 3 weeks.Any suggestions?

Just to reinforce: No, there's no need to add a powerhead or any other measure for water circulation. All my set-ups are fine without current unless this is specifically needed for fish or any other critters inhabiting the tank.

Humidity seems to be fine, too. It may be more a matter of personal preference wether you head for close to 100% or more like 80% (or anything in between).

Your plants look healthy. Nutrients seem to be on the low side - you may want to experiment with adding very small amounts of (good quality) fertilizer.
