If using CO2, place the rainbar below water level to reduce surface agitation(cause CO2 loss).
Hi All,
I'm using the Eden501 filter for my 1.5feet tank. My rainbar is fixed above the water level, but i do notice that there are people who have placed the rainbar submerged into their tank water.
I'm puzzled, which method is more advisable? Above water level or sugmerged just below the water level?

I noticed that if a rainbar is above the water surface, the water may splash onto the overhead light.
I normally have the rainbar below the water surface, but with the outlet holes facing upwards to create water agitation (for non-co2 setup).
P-L-E-C-O-R-Y=M-A-N-I-A!!! YEAH!
FLORENCE, capital of the region of Tuscany, has a population of around half a million inhabitants, spreads on the banks of the Arno, between the Adriatic and the Tyrrhenian seas, almost in the middle of the Italian peninsula. It is a city which bustles with industry and craft, commerce and culture, art and science.
I have tried both. It all depends on what your needs are.
The thing is, if you are having only fish or mostly fish and hardly any plants I would recommend that you have it above the water. I say this because my cichlids were hovering around the water surface sometimes gulping for air with the rainbar submerged. After I had the rainbar put above the waterline they stopped doing that.
For my planted tank I have it submerged. The fish are fine as they are being provided with oxygen by the plants.
For my shrimps I have it submerged pointed at a slightly upward angle against the glass. I seem to find this the best solution as it helps aerate the water and yet it does not create too much turbulence. Only thing is that you have to be careful that you do not point it too high until such that the water spurts out of the tank.
Hope it helps.
