    Oase Styleline 125 thoughts?

    My two Nano’s (60L and 37L) are both rimless but I still use glass covers. They are held in place with small clear plastic clips. My two tanks are a lot easier to keep clean than the braced 200L tank I had years ago. I’m still considering getting another 200+ L tank and would like to go...

    What Water To Use?

    I collect rainwater from a large shed with a rubber roof. I clean out the 210L water butt every now and then to keep it fairly clean. The lid on the butt is sealed to stop bugs getting in. I also clean the gutter that feeds it from time to time and there’s also a coarse sponge at the top of...

    Thanks to Darrel I use mostly Rainwater in my 60L and 37L Nano’s and I get very good plant growth, albeit easy to grow species from Tropica plus Moss. I only add DIY fertiliser once in a while. No CO2 and only a Sand substrate. The 60L is a bit overgrown at the moment.

    Oase vs Eheim Externals with Thermal

    I put a sponge on the inlet pipe of my Ehiem Classic 350 and it does a better job of keeping the media clean than the Biomaster. I don’t like it being in the tank but I had to install it to stop baby shrimps being sucked up. Luckily it’s at the back of the tank so you can’t see it.

    I’ve found this does over time reduce the flow on my tanks. Using clear hoses I can keep an eye on just how dirty they are. They generally get a clean every 12 months or so as needed. Not so important on the 16/22 hoses on the Biomaster but definitely on the 12/16 hoses on my Eheim.

    Bends in the hoses are inevitable in most setups but I try to avoid tight bends like that. I use standard clear hose so I doubt I’d be able to get a bend as tight as that in it even if I wanted to. I like clear hose (or pale green/grey) because I can clearly see when they need cleaning.

    I think the reason in this case is that I have a foam “pre filter” on the inlet pipe for the Eheim. I believe that some of the flow on the Biomaster bypasses its internal pre filter. This could be checked I suppose by doing the same on the Biomaster inlet.
