Fitting Fx5 With An Inline Uv......

[mattlee]

i have recently set up a new FX5 on my tank and have a UV filter i wouldnt mind fitting on the out take pipe but the pipes are only sealed at one end. the other end fits into the strainer or jet/nozzle while the sealed rubber end fits onto the valves on top of the filter.

so how do i get the ribbed cut end to connect to my UV making it water tight?

can you buy the rubber ends?

Looks like you'll need to get standard replacement hosing in the right size to me.

Bit of a poor design choice IMO, external heaters, uv filters etc just won't be do-able as is, atleast from what pics I've looked at...

Fluval FX5 Rubber Connector A20228 thats the product number you need also you will need something to make sure that the uv is fitted tight to the rubber end mate

excellent, thanks forby

I have a UV in-line and FX5.

I have seperate tubing rather than cutting into the standard tubing.

www.hoseworld.co.uk stock all sizes of tube - just pvc stuff is fine. Connect tube to the aquastop valve to the in flow of the UV filter, using a jubilee clip to keep secure, then connect the ribbed hose of the FX5 onto the exit flow of the UV, again using a jubilee chip to keep secure, back into the tank

Sounds like the best bet to me, the FX5 connectors are expensive anyway...

Plus you may want an external heater AND external UV filter one day

would the flow from the fx5 be to powerful for a uv ???i have fx5 and i am thinking of doing somethin similar what uv are people using ?

i have a vectron that i used to use with my rena xp3

Using an FX5 with all that flow would mean having the need to a UV filter rated for a high flow, there more expensive...but are availablke I am sure. If they can be used for an outdoor pond then they'll be rated high enough I would expect

Might be worth adding a second smaller filter with UV that have a low flow rate? Might work out cheaper...?

A key factor to using a UV is getting the right flow. If you want effective protection for bacteria, you must have flow low enough to have the UV be effective. If you are trying to control green water, a much higher flow rate can be tolerated but it must still be within the rating of the UV for algae. No matter what you intend to accomplish with the UV, there is a rated flow rate that cannot be exceeded if you wish to have a successful UV function. Each particular fixture has a flow rating for each given function. If you keep your flow at that rate or less, you can reasonably expect your UV to perform up to specs. If you ignore those ratings you can expect your UV to fail.

thanks oldman, ill look into the flow rates and maybe see if i can use it on the rena as it was before. the only thing is room for the UV unit as the FX5 has used the side of the cabinet that the UV can be fitted

 

[mattlee]

if it will fit in the cabinet would this suit the flow rate of a Rena XP3? according to rena 1350 ltr/hour but im sure it will be less with media added.

my vecton 200 is just too big for the cabinet now i have the FX5.....

 

[dave_oddballs]

you would have to have a pretty small external to use a vecton uv200, they are for 200 litre tanks, even the uv 600, for 600 litre tanks, wouldn't work with the flow of an fx5, hence why i can't use one. the fx5 is rated for tanks up to 1500 litres, therefore you would need at least 2 vecton uv600's in a row for them to work effectively.
the rena xp3 is rated for 600 litre tanks (i think) there fore you would need 1 vecton uv600 for it to work effectively, adding a uv to any filter pipe will slow flow at the best of time as water won't go through 2 90 degree bends as fast as a straight pipe, but you are slowing it down for absolutely no reason using a uv200 as it wouldn't work anyway.
i would suggest selling on the uv200 and buying a uv600 and using that inline on the xp3.

Hi Dave, just checked and mine is a vecton 300 not 200 but still not big enough..... my only problem is that these UV's are very big and the 300 was the biggest i could fit within my cabinet my tank is a 240L so not massive but is filtered well with the FX5 and XP3 in tandem. considering tank size and UV size is thee a smaller one available that would suit?

Matt.

 

[dave_oddballs]

yeah i see where your coming from i have an fx5 on my big tank alongside 2 eheim 2080's, i wanted 3 external heaters but can only have two as the fx5 wont fit one! same with uv's.
so what you need to do is get yourself the uv 300, and find out what is the max flow rate and get a filter to match, obviously if you get a filter also for 300 litres it would be sufficient for your 240 litre tank anyway, its annoying isn't it when you have a nice big filter sat there and you come across problems like this, but its one thing or the other, you go for the big filter with high flow rate, but the uv won't cope with that flow rate so you have to get a less powerful filter, you can't win! ha
