My thoughts on the stainless steel pipes still stands:On both if possible ?
As for the Aquario pipes (in my opinion):Hey, I didn't get these ones in particular but I got one from Amazon which is virtually identical except the cap on the intake is plastic instead of metal. I think it's called JARDLI
- Looks way better than plastic
- Easier to clean and dirt is less visible
- Robust, so very little chance of breaking
- Surface skimmer works well (only with a strong enough filter. It works on my Eheim 2217 but not my 2213.
- Output can be rotated 360 degrees rather than being fixed
- You have to get the perfect amount of air under the skimmer rim to get it to sit at the right level, which needs to be reset whenever the filter is stopped or you do a water change. Too much air and it will only skim a little, too little air and it sinks, potentially sucking in anything that comes by. You get the hang of it quickly though.
- I don't have a rimless tank so I can't use the mounting brackets. As a result I have to tape the hoses to a fixed position on the wall so the pipes are straight and not wonky.
- I wish the inlet pipe was much longer or at least had an extension. The pipes sit about halfway down my tank so there's not much opportunity to take in debris from the substrate. But alas, I knew this before I bought it. Would have been nice though.
- There's hardly any choice in terms of outlet design so you're stuck with the plain jet. I did buy some acrylic lily pipe adapters but I found they actually impeded the flow which is the opposite of what I was trying to achieve.
- Break-resistant clear pipes that can resemble glass when nicely cleaned.
- Flow can be adjusted 360 degrees.
- Modular nature of the pipes means you can configure the pipes with many different attachments for different scenarios. You could also use them in any position you like including in the shallowest of tanks because you can cut the pipes to size.
- Skimmer on the inlet means you don't have to worry about fish or shrimp getting sucked into the filter.
- Although the pipes themselves may be break resistant, the attachments are not. I've accidentally broken several of their attachments with very little effort.
- The version 1 skimmer sucks, and not in a good way. If you don't have an auto top off, forget it. It will become noisy or even cease to function. The version 2 is better but still not great in my opinion and still requires regular adjusting.
- The brackets and 'nuts/bolts' are cumbersome. They actually released some new easier to grip bolts but after everyone bought their pipes no less...
- They are too expensive for what they are (attachments included). I don't see how they cost more than some high quality glass and metal lily pipes? My only thought is the distance it's traveling before it gets to the UK market.
- Once you've trimmed the pipes they have next to zero resale value.
