Just Bought A Filter Eheim 2017

[goldfinger]

Back to ask a few questions on the unit I've bought the tubing is 12-16mm on the intlet and the outlet is 9-12mm 
I've been given one spray bar thats looks 12mm and I have two older spray bars I had at 9mm.
The tubing for the spray bar is tight on the 12mm as its the 9mm tubing. I have suckers and clips for the 12mm bar, but not the 9mm bar.
Question whats better restrictive 9mm or the 12mm I think the flow is smaller on the larger 12mm, but the 9mm did spray about 4"-5" outward direction haven't tested the newer 12mm pipe yet as the tubing is quite tight to get on? 
I was lucky as a barb on the 9-12mm quick connector was broken (female side) so I took off an old one that fits and mates perfectly on the newer male connector.
It came with two blue sponges Two lattice grids and that was it. I have ceramic noodles but the guy told me not to bother with substrat and stick cheaper K1 bio media instead as one is £25 2l the K1 is about £6 for 2l What are you guys running?
Do people mount spray bars in water or outward aggitating the water?

im not sure exactly what your asking,
 
i would just use filter floss/foam, as much as you can fit in there,
 
try heating the ends of the hoses a bit to make them slide on easier

 

[goldfinger]

Thanks Mikey I'll try heating the pipe up first. Yep I'm going to fill that void with floss and noodles!

you can mount a spray bar anywhere you want, thats really just a personal preference thing depending on what kind of flow or current you want in the tank,
 
the smaller the tube is, the faster the water will flow through it

 

[goldfinger]

I'm abit worried about noise TBF submerging it would solve the issues, but more oxygen with it out? 

 

[fluttermoth]

I run all my spray bars underwater, but pointing very slightly upwards, so the surface of the water gets a good ripple. You won't get any more oxygen by having it out of the water; oxygen exchange is all about surface movement.

 

[goldfinger]

Thanks Flutter! I'll try both out and see what the fish like?
I do have two spray bars and might Tee off the outlet and have water rippling across the whole tank just have to watch out for the lights.
I found snails on the canister sponges and did my best to get rid off them hope they don't get into the tank guessing the meds would kill them off anyways being invertabrates?
 
Just found out that micro bubbles are bad for Goldfish didn't know that!

 

[goldfinger]

Just bought some new media, rubber feet and ran the 9mm bar with new suckers and brackets.
Had a leak the pipe was not cut cleanly and the outlet screw was on too tight causing the tube to lift re cut the pipe flat and no more leaks!
Then I pulled on a connector too hard and lost about 10 liters on the carpet OOPS! LOL!

 

[goldfinger]

Quick question how long do I run the external with internal?
Plus to reduce the flow a tad I turned off the Ehiem 2008 pick up internal, is it safe just to leave it in the tank without flow or should I take it out completely?

 

[fluttermoth]

At least six to eight weeks. Why don't you just put the media from your internal into the external? Then you can take the internal out right away

 

[goldfinger]

I could Flutter, but just bought new media I want to mature, Plus the 300l tank is being cleaned this week just wanted the external filter to run under its own steam/bacteria. TBF I'm turning the 125l tank to Marine live rock, invertebrates, shrimp, sea urchins and possibly clams,  no fish though. I'm hoping the internal filters will be enough which means I still need the media in the original housing filters.
Thanks it really takes that long 6-8 weeks, when will I definitely know?
 
I do have space to fit the 2008 sponge I'll do it with that one filter and leave the rest.

 

[goldfinger]

just bought 3 litres of K1 media its like £3.33 per litre and I bought it to fill the void in the Eheim where the Substrat would have cost me near enough £50.00 for 3 litres.
I've heard good things and was thinking the best place would be middle of the canister between the two blue sponges and take out one fo the floss sponges if I can get more bio media in there? 

 

[fluttermoth]

I would still add all your mature media to the new filter. You can gradually start to take it out, after your six weeks is up.
 
You won't want that media in your other tank anyway, if you're going marine; marine filtration works completely differently to FW. Basically a combination of live rock/powerheads is the biological filtration in SW set ups; any internal/externals you run in marine tanks are for mechanical/chemical filtration only.

 

[goldfinger]

I get what your saying flutter!
I'm still in a pickle about setting the current Goldfish tank (125ltr) as an marine invertabrates tank, and the 300litre tank coldwater! 
I've got to get rid of the fin rot so ive left things to settle down and put back the carbon to get rid of the Malchate, then take it out again when the fin rot meds goes in.
I've got time to leave things until all good bacteria is forming on all media otherwise I could end up with spikes whilst dosing with meds?
Priority is to get the fish back on track TBF. Anything Marine can stay on the back burner, plus like you said its all going to take about two months before I even move them across to the 300litre tank.
