If you mix baking soda together with some water to make a paste that is great for cleaning the glass and helps remove tough deposits that have collected over the years, it's effective and non-toxic to fish.
I have an Airvolution AV4, bought just a month ago and it too is VERY loud - I don't have the money to buy another just now but if I had my chance again I would have plumped for the Eheim so go for it!
Sorry for the late response, thanks for all your input.
Yeah it looks like I made a massive error in replacing all of the tank water, the tank is now cycling which is far from ideal so i am doing 50% water changes every 2 days to keep the ammonia levels down as I have no spare cycled tank to move the fish to.
I feel a bit foolish as I thought I was doing them good but I learn for next time.
On a positive note the tank itself is much cleaner and the fish are improving despite dispalying signs of SBD. I have been feeding them peas and using Interpet Swimbladder disorder treatment so I am hoping they will be back to their normal selves within a week or so.
The old version of the tank was fully cycled and had been for around 6 months and the fish were perfectly fine during this time. The reason for emptying out the fish and entire contents of the tank was in order to fully remove all rotting plant matter, clean all sides of the tank thoroughly, add some new gravel / plants / ornaments etc and install the new filter with clean water - I figured a full strip of the tank would be more beneficial to the fish.
I cut up the old filter foam and spread it out amongst the ehfisubstrat within the new Eheim 2217 filter so that the good bacteria can spread amongst it so I'm not sure whether it's new tank syndrome that they are suffering from - plus its also worth mentioning that one of the Orandas was displaying signs of swim bladder problems whilst still in the temporary tank prior to being released into the new setup.
I don't have a testing kit to measure the condition of the water but if you really think this is the issue I will purchase one and examine the results.
I have a 200 litre tank with 3 Orandas in it, they are around 6 months old and have been growing happily with no problems.
Yesterday I cleaned the tank out and installed an Eheim 2217 canister filter along with a 48" air curtain, a couple of new ornaments and a few silk plants (they ate & destroyed all the live ones and were dirtying up the tank previously) - all of which were thoroughly cleaned and scrubbed in hot water prior to entering the tank, obviously with no chemicals.
The fish were moved temporarily to a much smaller tank while I cleaned out the main one which made them a bit miserable understandably but after setting up the new tank they were moved back into the main one and initially seemed fine.
However today 2 of the Orandas are displaying signs of serious distress, neither of them are swimming properly and they both swim upside down, jerking around occasionally and seeking places to hide away which is very unlike them - the 3rd Oranda doesn't seem himself but so far has displayed none of the symptoms.
The tank is now the cleanest it has ever been so I cannot understand what could have brought these issues on? They would appear to have swimbladder problems but both fish also have red vein-like streaks on their tailfins which also concerns me.
I feed them Hikari Oranda Gold food soaked for 15 mins prior to feeding twice a day.
I am looking to install an air curtain to run along the back of my aquarium as my current air pump has given up the ghost and it seems a good opportunity to give it a go as I think it would add an extra bit of decoration to my tank.
The tank measures approximately 46" across so I'm planning to get some flexible piping to cover the entire width but would anyone know what type / power of air pump I would need to power an air curtain of this length effectively?
There are so many air pumps out there with varying degrees of power I am unsure as to what power I would require. I don't want to pay over the odds for extra power I don't need but equally I don't want a pump that isn't powerful enough to push enough air down the pipe.
If anyone could help me with this that would be great - any recommendations on specific brands / models would be even better.
The plants are all soft and there are no sharp edges anywhere in the tank so no risk of injuries I don't think.
I think there is a chance we could swap one of the males, not ideal as we've grown quite attached to all 3 of them but if we have to swap one of them then we will to make the Blue's life more pleasant - I guess it's the luck of the draw when you buy young fish, no way of telling their gender.
I've bred Telescope Moors before, a long time ago when I was a young teenager but my knowledge is now pretty shady - do goldfish that are kept indoors go through breeding seasons or will this behaviour by the males be pretty much constant? I'm trying to work out if the Blue will get any respite from the males at all.
I have no heater in the tank, would regulating the temp make any difference?
