    Selling plants - how much?

    I'm selling all the plants in my aquarium (see for sale listings). I have no idea what a fair price should be. There are pictures in the for sale section on this forum. Is it naive to think I bought them way smaller for about £3-4 a plant and they are now FAR bigger so they should be worth at...

    Boyu CO2 diffuser - so far so good...

    Just bought one... let's see if it's any good in 10 weeks when it finally arrives from HK..

    dennerle disposable co2 regulator

    I have one of these Dennerle systems and can tell you that the Halfords bottles don't fit. Nor do the other more usual set ups available in the UK. I have found a couple of places online that sell the bottles but almost all are in Germany. If anybody knows for certain where I can get an adapter...

    Power head / flow pump question

    Thanks for the response, but my pump is just like a propellor in a housing. There's no outlet.

    Power head / flow pump question

    Hi, I just bought one of those super cheap 3000 l/h flow pumps on Ebay. It actually appears to be pretty well made (which surprised me for what I paid for it). However, has anyone tried reducing the output of one of these? I'm considering either wiring in a dimmer switch to reduce the power to...

    Algae questions and any other advice....

    Actually, I think I did understand the article which is why I said "It also implies that if I change 20% of the water, I still add the same level of nutrients.". I was just confused as to why every EI article talks about a 50% water change. Now however it is making sense. So I presume I can...

    Algae questions and any other advice....

    Sorry I didn't make it clear.... I have a 30 litre tank that I fill and preheat that I use for water changes. I'm reluctant to get a bigger tank to preprepare water changes as it would have to sit in the garage. So I guess I'm doing a 20% water change every week... I've read Ceg's article on EI...

    Algae questions and any other advice....

    What does having a water softener have to do with EI?... because of what you responded to one of my previous posts: "Water softeners that use salt or brine (NaCl) are not a good idea, primarily because the sodium content can become problematic."... As a result of that I thought I couldn't use...

    Eheim 2213 & flow rates question

    Hi, I have an Eheim 2213 external filter and the standard Juwel filter in my rio180. I think the Eheim is supposed to be 400 l/ph, but that would imply it would fill a pint glass in about 5 seconds. I think the flow on mine might be a quarter that level at best. It's also making the occasional...

    RIO 180 - New tubes and reflectors needed.

    Hi, the first question would be if your Rio has T5s or T8s (the 1 inch diameter tubes). If it has T8s, it will take standard 30W 3 foot tubes (at least my Rio180 does...)

    Water Softener plus any other advice

    My first post... I have a Rio 180 that's been in service about 6-8 weeks. I use the internal filter and an Eheim 2213. I have the normal 2 T8s of unknown age (second hand tank) and 1 new T8 (so 90W in total). Currently, I change about 10% a week with water that I have taken directly from the...
