Thanks Coralline - my understanding is that the flowrate on Eheim 2260's cannot be adjusted.
My plan is to buy one of little green clamps and use that on the inlet pipe, that should help reduce the amount of bubbles down to an acceptable level - then I'll direct the outlet upwards to create more water movement, that should sort it!
This may be difficult to answer but how much movement is normally required? I keep fancy goldfish and they aren't the strongest swimmers, they are already struggling against the flow of the filter output and my aim is to keep the water as calm as I possibly can.
It is connected to the output of my 2260 filter and its functionality is fine but basically I am getting a thick white mist of bubbles which obscure a third of the tank even when I aim it into the wall or a corner. I have recently discovered though that if I unscrew the final piece of the diffusor (basically the cover which helps the water form a jet) then no bubbles come out which is great but do you know if the water coming out will still be oxygenated? I know it sounds like a strange question but if I don't "see" bubbles I just don't feel like oxygen is going into the water, am I right or wrong?
Sorry for butting in but I now feel obliged to provide an update on my Novatouch LED experience!
I ordered a 60" blue / white LED bulb with a dimmer but opted out of the "UV" feature.
I set up my new tank on Sunday night and I am impressed with the Novatouch bulb. As expected it isn't as bright as my old T8 bulb in the 200l tank but for that I am thankful as I didn't really like the piercing white light in the old tank anyway. The LEDS emit white + blue light (you can have either / or both) and it lights the tank completely with no dark spots, albeit dimmer than a traditional fluorescent bulb but I think the fancies appreciate that.
I was concerned that the light from the bulb wouldn't penetrate the water bearing in mind the tank is 30" high but it has no issues and overall I'm really happy with it.
As mentioned earlier I didn't go for the UV option as I am dubious about the claims - never used UV anyway so didn't see it necessary but as far as the light output is concerned I am very happy.
I don't know the brand of filter myself but principally if water is coming in through the bottom and going up through the filter then your media needs to be arranged as follows:-
Ceramic rings (if you're using those) Coarse sponge Bio-media of your choice Fine sponge and /or filter floss
Bio-media must always go after coarse sponge (which filters out the larger particles of waste) otherwise the bio-media will get clogged up too soon, also the floss must go last using the principle that larger pieces of debris will have been caught earlier meaning the floss won't get clogged up.
How may litres does the tank hold? I'm guessing if it's 5ft it'll hold probably at least 350 litres - the volume of water in the tank is a major factor when choosing your filter.
The fish you keep will also determine what filter you go for, if you're keeping goldfish they're pretty messy so you're best going for a filter that is rated at least 3x the volume of your tank water, if not more.
So for example if your tank holds 400 litres of water, you'd best go for a filter that is rated for a tank of 1200l.
I only use Eheim filters so can't comment on any others personally - my current 200l tank has an Eheim 2217 on it (rated for tanks up to 600l) which I cannot rate highly enough, brilliant filter - my new 600l tank which I am in the process of setting up will have an Eheim 2260 on it (rated for tanks up to 1500l but I'm putting the 2217 onto the tank too).
You can pick up decent Eheim filters second-hand off Ebay, they can be a tad pricey brand new but it would be a great investment anyway. Eheim build filters that are bomb-proof and go on for decades with the right care.
Totally agree with your viewpoints on the UV thing, I think that's a pretty far-fetched claim too so won't go for the "UV" version.
The bulb comes supplied with clips to fix to the edge of the tank, I don't have a hood but may fashion a cover for it especially if the light from the bulb is leaking into the lounge and making it too bright.
Novatouch is a UK company and they state the bulbs are made in the UK, they've had good feedback on their ebay site - to be fair their website could do with a re-vamp but I think they're a relatively new-start company so can't hold that against them.
I'm looking at installing LED lighting on my new 60x30x20 tank but choosing what brand / type / size is causing me a real headache.
I've seen a manufacturer called Novatouch who make a great looking LED light which matches the length of my tank. It has a moonlight feature which will make the tank less bright in the evenings and comes with a dimmer which is a nice little feature - does anyone know much about these lights as I can't seem to find many reviews and the only ones I do find are from marine-keepers, a couple of whom moan about the light output saying it's a bit dim but I guess it's all relative isn't it?
Now, I keep fancy goldfish so although light is important to me in terms of keeping the fish healthy / maintaining their colour and of course to be able to view them properly I'm not growing corals or trying to grow a thriving planted environment so should I be obsessing over the light output? The tank is 30" deep which could be challenge for LED to penetrate properly, another of my concerns.
The price of these lights seem good too so chances are I'm going to take the plunge but does anyone know enough about these to say "steer clear" or even "yes these are great" - your input would be greatly appreciated.
