    RO unit worth it?

    Not only an assumption, but there's also a huge amount of marketing aimed at selling us ever more expensive and complicated filters.

    Smelly Whiskey Barrel and other issues....

    Hedgehogs and toads would help. You can make suitable hiding places and hope they come. Or sometimes a wildlife hospital will be looking for homes for rescued ones when they are ready to be released.

    That won't help. :) If they were still the best filters on the market and would last a lifetime, they might get away with high prices. Not any more.

    Can someone help me understand what's causing my GH to increase?

    Yes that sounds like a swim bladder infection. Possibly a neurological condition, but that seems unlikely across many fish of different species. Swim bladder infections are difficult to treat, but an 'internal bacteria medication' could help. Lots of people are keeping all the fish species you...

    Smelly Whiskey Barrel and other issues....

    I love hoverflies. :) Perhaps you could put some of the water you take out when waterchanging into a bucket or tub. Put as many of the Rat-Tailed Maggots as you can catch in it, and put it somewhere unobtrusive like behind the shed. Some dead leaves would probably be good for them. :)

    I'm not surprised. They built up a great reputation over many years. But it doesn't take long to lose that sort of reputation if you let the design, quality and/or customer service go downhill. And it's not easy to rebuild a reputation once you've lost it. They need to get their act together...

    Play pit sand is cheap. It's also quite nice as long as you like the colour, which is usually very pale. Quite similar to the sand in your pic in fact. :) It's very fine-grained, and some people find it packs down. Malaysian Burrowing Snails will fix any problems in that area. hth

    Biomaster 350 or fluval 307

    Algae Nightmare :/

    I think that's your biggest problem. Your Tropica Specialised fert won't hurt your shrimps. If the ClearX does what is claimed for it, it's bad for plants and good for algae. I would remove the ClearX and start dosing the fertiliser; I don't like to make too many changes at once, so I would...

    After a good soak with a few changes of water, you can add some Daphnia or similar pond creatures to the soaking water. If they thrive there's not likely to be anything toxic still leaching from the wood.

    Pest Snail how to get rid of

    They love to eat fishfood that your fish have missed. If you overfeed they will breed like crazy. Without excess fishfood they mainly eat algae. If you have a lot of algae the snail population wil increase; when there are lots of snails, the algae goes down and so does the snail population...

    Nerite Snail Help

    I bet that if you were thinking of changing them using expensive aquarium products they would be all for it. :) Cuttlefish bone works, and it's cheap. If you don't trust your water test results have a look at your water supply company's website for a drinking water quality report.

    Eheim filter flow ratings?

    Some filters, including most internal ones, are supplied with media. In my experience they still don't manage the flow claimed on the box, even if you take the media out. And with an internal you can take the head out of the equation. And pipe lengths and bends. I've got some very good filters...

    Old hatchery pix

    Yes it is. I've mostly bred fish that care for their babies, like cichlids. It's great to watch, but things can go wrong, so yes, it is good to see the babies grow old and big enough to leave home. :) Without parental care you either leave them to get on with it and hope for the best, or set up...

    Old hatchery pix

    I don't know about Nerites, but if tiny snails, like Ramshorns or Tadpole Snails get into the tank I never see any more baby rasboras until/unless I can get rid of the snails. Some-one on here has probably got Rasboras, Nerites and Amanos together. Hopefully they will spot this and chip in.
  31. sparkyweasel

    Old hatchery pix

    I believe that letting the parents raise the babies is the best way. They won't spawn again until the babies leave home, so they don't get exhausted by frequent repeat spawning. I think they find it distressing to lose their babies before they are ready to send them away. I used to move them...

    Old hatchery pix

    Hi, the only rasboras I've bred were Chili Rasboras and Strawberry Rasboras, and for those I didn't do anything special, just kept them in a densely planted tank with no snails. A few fry appeared now and then, but not really a proper breeding scheme.

    I normally let the Angels choose their own partners, so here we have a 'normal' fully striped male and a gold pearlscale female. Hans and Lottie.

    That's as sure as you can be. :) And heathly ramshorns are a good sign, they are quite sensitive to (some at least) pesticides.

    RCS keep on dying

    That's a big filter for a little tank. What filter is it? And what media are in it? Have you had to restrict the flow a lot? It's possible that the flow is too slow for it to work efficiently. There may not be enough oxygen passing through, or it may have stagnant areas. More info would help. Do...

    How decent is the Fluval LED light that comes with the 200L tank?

    I wish they wouldn't. We know lumens are not very useful. We know the the volume of the tank doesn't determine how much light it needs. Different shapes of tank with the same volume will not need the same lighting. The amount of light does not relate to how difficult to grow a plant is. If plant...

    Getting rid of scuds.

    You could state when advertising your plants that they come from a tank with scuds in, and that any buyers that don't like scuds will need to treat their purchase before adding it to their tank. Most people won't care, and those that do will know where they stand.

    Starting a Fishless Cycle - Am I too late?

    Chili Rasboras like a bit of swimming space. If your 20l is long and shallow that would be a lot better than if it is tall and thin. Volume isn't the only factor, and probably not the most important.
  50. sparkyweasel

    White spot

    Those spots still on the fish will eventually drop off and release hundreds of tiny free-swimming babies. That is the stage in their life-cycle when medication can kill them, so you need to keep the treatment in the water until after the last spots have disappeared.
  51. sparkyweasel

    Going filterless?

    Without the filter, perhaps you would have syphoned it out. Then it might cause less algae. If it decomposes in the filter it pollutes the tank water a lot more than if it's in the bin. :)
  52. sparkyweasel

    Co2 troubles

    That is a valid concern if you have livestock in the tank. You need to make your adjustments when you are available to observe the inhabitants for any signs of distress. If you haven't stocked the tank yet, you don't need to worry. Your plants won't come to any harm from overdoing the CO2.
  53. sparkyweasel

    How decent is the Fluval LED light that comes with the 200L tank?

    I agree with John, you need a complete fertiliser.

I would certainly try other options before...

    It can be useful to keep your floating plants confined to one (or more) corner, using a cordon of fishing line between two suction cups. They don't get as much battering from the surfae agitation, and don't get swirled all around the tank.
