Hi again, (Sorry this got long...a little chatty lately)
I have been reading further on the board regarding sponge filters with plants. It is funny, when when I was talking with someone in the fish store about me using the Powerheads in the past, I could not remember what I had them hooked up to in my 100 gallon Cichlid tank. I went online to look up sponge filters and it triggered my memory that it was the large grey tone sponge filters that I had on each back corner of my 100 gallon. It is weird that I remembered the small sponge filters that I used as a kid but not the ones I used as an adult. It has been at least 7 years since I got rid of my 100 gallon tank.
Anyway, my question is, for those of you who have larger tanks with LIVE plants and use sponge filters what do you work it with? The power heads can really make a lot of water movement....depending on the power of the unit. I think I do remember though that you can control the airflow to reduce power. It was fine for my cichlids because I did not go the plant route with them -- they can mess decor up and can be sand movers, etc. The water movement that I had seemed comfortable for them. Also, I did not want to take time to do the live plant thing at the time.
If we decide to do live plants in my daughter's 14 gallon tank, the back filter I have on there now (Marineland Penguin 150 BIO-Wheel Power Filter)
may be too much for plants. The water movement does not appear overkill that much for the fish but not sure if it will be ok for the plants. I got the one size up for the back filter than what was completely necessary. I was not thinking live plants at the time and actually for some reason I did not think that the one size up would put out a lot more water movement. I started to wonder this after I set it up. The tank came with a small back filter, but I like the biowheels, so I bought a Marineland Penguin BIOWheel 150. I also liked the fact that there are two slots for two pads. Not sure if the 100 has this. I am not sure how much different the water flow would be with the 150 compared to the 100. My powerheads always gave out more water movement than my back filters it seemed.
