Sorry I missed your question until now, 400 gph should be good for a 55 gallon.Puff said:when calculating the rough GPH that you would need for your tank. would you take into account the GPH of your filters as well? or are they considered totally separate?? ive always wondered that
ive got a 55 gallon, with one 330GPH HOB filter, and another 170 GPH biowheel filter. so that adds up to...500GPH.
how much would i need for a powerhead? or is it the 200-sumthin' GPH the calculator worked it out to?
thanks el twitcho, sweet thread
What I did was used a quickfilter attachment when my piranhas were still young, worked pretty good for me and it's a useful thing to have lying around when you want to clear your water real quick.scrappydoo said:One more thing to take into consideration when choosing a powerhead is the size of your p's in relation to the strength of the powerhead. A 2-3" p is gonna have a hard time overcoming the suction of a big powerhead.
I lost a few this way. I would turn the ph on whenever I thought my p's where big enough to have it back on, and I lost one everytime I was wrong.Personally, I'd wait till they're at least 4" for a strong powerhead.
The hole is insulated with epoxy and is waterproof, since the powerhead is meant to be submersible, they covered that pretty wellzrreber said:What about the cord coming out of the top of your powerhead? isnt there a way that water could get inside and fry your fish?
AC's are submersibleedmond said:are all powerheads submersable? I just purcased an ac 802 and it has a lable on the side that reads "water line" then it goes on to say do not immerse beyond water line. also do I have to worry about my plants with too much surface agitation produced by the powerhead.
The line you are seeing is that you are NOT supposed to have that line ABOVE the water line.edmond said:Thanks for the fast reply. I always get nervous about putting something that's pluged in to power, under water. Just so I'm clear the warning on the side is just a disclaimer? Other people have put the Aqua clear 802 complety under water before?
You should direct that to the Plants section of Pfury. You have a better chance of getting a good answer there!edmond said:thank you (I feel dumb, I should learn to read). How about my other question, The one about plants?
