I m using a 3-footer tank and using 2 powerheads for water circulation making a total of 5800 ltr/hr. Total wattage is 66 watts. Just for record, the second powerhead was newly introduced after a replacement of a spoilt one. Wattage wise, < than 10 compared to the new one.
What I have been observing, my mushrooms and green button polyps looked like a little bit annoyed with the new introduction of the powerhead. Can it be bcos of the new powerhead which gives an xtra 700 ltr/hr boost to the tank or it is bcos of the xtra wattage for the new powerhead.
, is there any other method create water circulation without using powerhead in the tank?
