So it's you!!..
I knew I'd read about someone using one of those pressurised pond filters on their tank.
Looking into it myself as an alternative to a larger (better designed) sump..
Are there any concerns with the inlet strainer?? I mean with fish, children, small cars getting stuck to it?
Sorry to hijack a little but the hole in my tank can only really handle about 3000 lph and I want more like 7000.. the pressurised pond filter setup looks tailor made for just this... were there any considerations/alterations in getting it set up for aquarium use?
For the strainer/housing, the only problem I see is the size of it and having it in the tank. I've not had problems with sucking in stuff it shouldn't (cars and children I mean :clap
. There are holes about 5mm throughout it, so I'd imagine very small fish would be in trouble.
The main issue you would find with having one is where to put it. The canister isn't much larger than a Eheim 2080 but the hoses (at least on mine) attach horizontally at the top of the canister. Then theres the pipes. I use 40mm (I think) ribbed pipes which need room to bend as to not put pressure on the joints. Luckily for me, my tank has metal railings so for in/out of the tank I hooked the pipes through jubilee clips to keep them in place. I also use a couple of UPVC pipes to help direct the ribbed pipes into the tank. If I were to do it again I'd look into using rigid piping and cements/silicone to fix the pipes in place.
It undoubtedly works great and is a monster compared to traditional canister externals (perhaps save the Eheim 2262), and I doubt my tank could run without it. It has it's problems, I'm scared of mine so I leave it alone. Unless your tank is like mine I don't think it's necessary really. But I'm happy to talk more about. I could take some pictures of how mine is set up if you want?
Wow ! That a rare thing ?
I've seen maybe 5 pictures of fish like this, at least 3 were Panaque nigrolineatus. Maybe I should ship it to Japan?
That's cool!
I don't think anyone knows why this happens do they? I know there is debate about p. aurantiacus but unless I have missed it no one will categorically state the reason they turn (and can then turn back).
Very odd, have you asked the bods over at PC?
ETA - whats in the tank on the left?
I think some of the causes people make an argument are pH shift, water quality, stress etc all of which are reasonable but difficult to prove. I could potentially isolate the fish and try to trigger it to change back.... but I'm not.
Apart from P. aurantiacus, I've only seen a couple of species with this sort of colour morph. Psuedorinelepis genibarbis (which I posted here, search for xanthic pseudorinelepis) and a Pseudacanthicus sp. And theres Panaque bathyphilus and Hemiancistrus pankimpuju both were described as completely without pigment.
The tank on the left is for my 40cm Panaque nigrolineatus and couple of odds and sods plecs.
