    My neighbors are complaining about noise from the Tidal filters

    I've used Tidals before and had zero issues with sound. Virtually silent. Helped by the fact that the impeller is inside the tank which muffles any sound further (and means they automatically resume functioning without being primed in the event of a power cut). Unless you mean the sound of...

    21" deep freshwater lighting

    My largest tank is 67cm deep (26.3" -ish) and my Fluval Aquasky lights work just fine for plants. Bluetooth, fully programmable etc. On the pricey side though and if the programming isn't important to you then there are much cheaper lights out there. As Colin said, it isn't deep and standard...

    having problems with a FX4 filter

    Sounds similar to a problem I had with a brand new FX6 (see this thread). Significant juddering from the hoses like the pump was turning off and on and low and inconsistent flow. At one point it cut out entirely and needed to be turned off and on. I'd tried disassembling the impeller etc and...

    UK - Northumbrian Water Reports 2020 and 2021 - INCREASES in hardness that are worth knowing

    It's also worth noting that the "average" is an average of the highest and lowest from tests at different properties within the water board's delivery area. It doesn't mean that the average hardness out of any particular tap or property has changed, although it might have. It might just be...

    UK - Northumbrian Water Reports 2020 and 2021 - INCREASES in hardness that are worth knowing

    Northumbrian Water uses surface water (from rivers and reservoirs) and then blends them. I imagine any changes over time to the water parameters will result from the changing blends. I.e. more water captured from a river with higher hardness in one year, more from a river with lower hardness...

    Sudden Nitrite (not Nitrate) in Tap Water

    As the OP, I can only agree!

    Sudden Nitrite (not Nitrate) in Tap Water

    Thanks. Yes, I use Seachem Safe (which the powdered version of Prime - just a bit more economical on large tanks). That was my thought too. I'm just always slightly sceptical on the whole "renders it inert" thing as I've never seen anyone really explain how that happens. That said, I have no...

    Sudden Nitrite (not Nitrate) in Tap Water

    For those who are interested, this gets weirder and weirder. I swapped the problematic Pozanni nitrate filter for another one (unopened). The nitrite is zero once more, proving it was that filter cartridge. However, the new cartridge is stripping all of the carbonate hardness (kh) from the...

    Sudden Nitrite (not Nitrate) in Tap Water

    Thanks. I've actually now ruled out the hose and have managed to find the surprising culprit... The hose I use is food grade and specifically free of phthalates, which is the bit that the non-food grade hoses use to keep them flexible. I've done more water tests than I can count this...

    Sudden Nitrite (not Nitrate) in Tap Water

    Thanks. It's connected to a hose that is permanently connected and used exclusively for my tanks. Connects to the tap Through my garden and through my office wall Then to an inside hose tap The only way to get running water in my office. The hose is food grade and never disconnected...

    Sudden Nitrite (not Nitrate) in Tap Water

    Afternoon all, Living in South East London, I've traditionally battled high nitrate levels in my tap water. Today though, I have a rather different issue. Having just filled a 200 litre bucket ready for tomorrow's water change on my 200 gallon, I dipped a test strip in. When testing my tanks I...

    Anubias flowers opening underwater...

    So cool. I love flowering aquatic plants. My Aponogeton Capuronii frequently sends up flowers above the surface which find the small gaps in the cover glass. Video of mine below. They flower a purple/mauve colour but I forgot to photograph it until it was dying back (they flower, die back...

    Java fern flourishes in one tank, dies in the others

    Thanks both. Yup, all tanks stocked. pH is around 7.2 in all tanks so don't think it's that. I do have high phosphate levels in my tap water, and therefore my tanks, but (a) that normally causes an algae issues, not complete plant die-off, and (b) that's the same in the tank that's flourishing...

    Java fern flourishes in one tank, dies in the others

    Afternoon all, I have Java ferns in three tanks. The water parameters are the same in all, the lighting is the same (as much as can be determined over different tank sizes) and on the same time and intensity settings. Fertiliser use is the same across all tanks. Yet in one tank the Java ferns...

    Is an FX6 enough?

    I have an FX6 as the sole filter on a 193 US gallon tank and have precisely zero issues. Tank size is 171cm length. It will depend on your proposed stocking to a degree but remember it is doing two things: Filtration An FX6 is easily capable of filtering a reasonably stocked tank. My 193 has...

    Big problems in Rio land

    Out of interest (and feel free to direct message me this if you'd rather not post it), who was the retailer? If my life calms down enough at some point and I find the energy to deal with the same problem on my Rio 450, it would be helpful to know if we have the same retailer and that they've...

    Fluval 407

    Just check you can get the hose and the mounting brackets through the small semi-circular gaps at the back of the Juwel. All of the Fluvals use special corrugated hose and the FX series using these big, chunky rim connectors. Not sure they'd go through the small cut outs so you might need to...

    Faulty Juwel brace bars

    As on the previous chat from yesterday, I've got the same problem on my Rio 450. 14 months old. Their engineer told me that it is not a structural issue, for whatever that's worth.

    Big problems in Rio land

    I had seen this previously when researching my own issue. The official link is here. Interestingly they say the braces are for their "older model" aquariums and they list suitability up to the Rio 400, which is the older model that the 450 replaced. So I'm not saying that their current...

    Big problems in Rio land

    No, I didn't/haven't. I have an 8 month old, my wife isn't massively well and I just haven't had the time or the energy to have that kind of argument at the moment. I did a bit of Googling and there were others with precisely the same issue and their tanks hadn't busted so I've just had to...

    Big problems in Rio land

    For what it's worth, it sounds extremely common with Juwel tanks. I have exactly the same thing with my Rio 450, picture attached. It's 14 months old. I emailed them two weeks ago and received the same response: "The cross braces are not a structural part of the aquarium so please be assured...

    Who keeps barbs?

    I have a 200 gallon heavily planted tiger barb tank. Currently home to 12 cherry barbs, one rainbow shark, 24 "normal" tiger barbs, 24 green tiger barbs and 12 gold/albino tiger barbs (which will come up to 24 next month and finish the tank off). I love it. My favourite tank. Constant activity...
