i only have 1 820 for my 4ft.. everything works well.. choosing of wavemaker is really depends on the amount of flow rate u wan.. there is no suitable or non-suitable for my case
hi, as the flow rate is too low for my sun coral.. and i'm trying to add more flow by introudcing a wave maker but seems like there is no wavemaker small enouigh to hide behind the rocks.. anyone have any suggestion?
seio 620 is enough for mid to high flow.. 820 will be consider high flow liao le... i use to have 820 for my 3ft tank and my sun corals are happy with the flow.. as for 2.5ft i guess its almost the same..
