I am thinking of upgrading my Fluval 204 to a sunsun/aqutop canister over the next little bit and want to know if the HW302/CF300 will indeed be an increase in flow.
I have tested the real flow of the 204 and it is around 100-110GPH with media.
It is rated at 180GPH.
I guess what I really what to know is has anyone tested the real flow of the SUNSUN filters and how they compare to the rated flow.
Can anyone tell me how long the spray bars are that come with these filters? I have a standard 30G with the Fluval 204 Output on the back right of the tank and a koralia nano 425GPH on the bottom left and the flow is okay but there is some slow spots in the center were detris/mulm can not be moved easily due to plants.
I would like to change the flow pattern to have a spray bar aimed towards the front of the tank running the majority of the length of the tank to help with water movement.
i put together a comparison chart for anyone interested. I think I'll do a 303A for my 55 gallon.
Stupid question, what does the UV stabilizer do?
9.1" x 9.1" x 15.6"
10.2" x 10.2" x 16.9"
11.4" x 11.4" x 19.1"
Thanks for the info. I'd like to add "Confirmed" Hose Sizes to this list. While this thread is very informative, it is getting very long. I've seen a number of people asking the same thing recently, but no firm answers. (Perhaps the OP could amend the initial post to include noteworthy additional information )
I purchased a SunSun 304A six months ago and it is an excellent filter IME. Well made, quiet, and decent build quality. The only issue is that I'd like to run a Hydor ETH 5/8" @300w, but the 304 uses 19/22mm (3/4") tubing. I went ahead and spliced in the Hydor, but it has significantly reduced the flow. I am considering an additional HW-302 for Bio filtration, flow, to run the Hydor. I'm not going to go ahead with the purchase until I know the hose size.
Compared to Eheim, SunSun is inferior in durability, craftmanship and ease of use. The SunSun baskets don't fit well inside the canister, get stucked and hard to remove, basket handles come off, and the plastic gets brittle and breaks. The SunSun intake and output tubes aren't durable either, they easily crack when changing the tubing.
Just bought an Aquatop yesterday.
Why? I haven't had a cannister filter in 10 years. My last one was an Eheim. Never again. It was junk. Parts were expensive (and it broke often).
I bought a 404B on 09/16/11 and so far its been problem free.Ordered 4 liters of odyssea glass bio rings and 4 liters of SeaChem Matrix.I plan on buying a fx5 also and i think this will be enough media for both filters lol.
where all the old user at?
do report back, I just went through 38 page about this sunsun filter.
since this was start back in 2010 and its almost 2012 can someone report back with info on how your sunsun is doing... if this filter can do a good 2 yrs i might just pick one up myself.
