    Spray Bar holes - Making them bigger

    yes itll work fine, but it will decrease the ferocity of the flow through them obviously. I also drill downward facing holes to send some flow down the back of the tank.. this can help reduce dead spots directly under the bar.

    Fluval Fx5 & Co2 Diffuser

    any co2 dump is minimal.. co2 disolves so fast in water that any gasses in the dump are likely to be only air anyway. The noise level is not added to by the co2.. because of the route of the water flow through the filter. The gas has a very long way to go before it hits the impeller.

    Fluval Fx5 & Co2 Diffuser

    I run an FX5 with a rhinox 5000 directly under the intake strainer.. its no problem at all. I find my CO2 usage much more efficient than placing the diffuser somewhere else 'in tank'.

    Help with flow...

    drill the holes bigger :) also, drill a hole or 2 facing downwards.. keeps the back clear and prevents deadspots

    Cheapest place for sintered glass media.

    with the amount of turnover your filters going to have on such a small tank Garuf, filling it right up with media is probably a waste of money. As Ed said on a different thread.. a tank is only going to produce so much NH4, so only a culture of a certain size is going to form anyway.. with a...

    Cheapest place for sintered glass media.

    unmodified, the media capacity of an FX5 is only 5.9 litres.. are you sure you got your maths right?

    High water turnover - discuss :)

    hehe surfs up indeed! Im aiming to upgrade to an FX5 and rig up something to split the flow between a full lateral spray bar, and another outlet washing down the back wall, or something similar.. that way it should lesson the ferocity and provide a good mixing action, will see how it goes.

    High water turnover - discuss :)

    Im trying to talk myself OUT of buying more stuff!! :lol: Your not helping!! :lol: Yes, the aesthetic angle is a really deal breaker.. while I dont like to be led by the trends of the world there's no doubt that a tank devoid of any hardware is a more beautiful one. Flow seems to be much...

    High water turnover - discuss :)

    Due to this subject cropping up on lots of other threads I thought Id start a proper thread for it, so we can hammer it out!! *nudge Clive* :D The subject is filtration and high turnover.. Back in the old days a few years ago, Tom Barr was advising low turnover due to the fact that ferts...

    New Filter for 240L Aquarium

    yeah but at 40 quid cheaper Id be prepared to take that risk.. £125 i can justify, £165 i cant.

    New Filter for 240L Aquarium

    well mine is over 3 years old.. so its actually only a 304.. not the 305 that I always say it is. Maybe at the end of the month, liking the look of that FX5.. only £125 looks like a bargain.

    New Filter for 240L Aquarium

    New Filter for 240L Aquarium

    I have a 305 on a 235litre.. had one for years and years, amazing bits of kit. Id stick with it. Its plenty big enough. If you have dead spots due to scaping, then put in a powerhead.. no matter how big the filter is, youre always going to have deadspots somewhere.
