I had a 104 once, it barely made it past 1 year and had the original 'clogs every 5 minutes' aquastop valves. I have a 205 on my Axlotl tank (was a swap at my LFS for an even worst filter they had sold me, a Sicce Genio1) and frankly I hate it.
I have the opposit issue. Mine cloggs within 2 weeks and suffers extream chaneling, even with with ceramic media in the bottom and top baskets to spread flow out (in theory)....
They do however do a good job of keeping their flow rates high, mainly because there is hardly anywhere to put any media in them probably.... lol
Dissagree on flow rates, but media capasity is hardly envionable, thus agree with the latter part
As to tetratecs, they seem nice units, but I am reserving my judgement for when people have been running them for longer. There have already been some reports of manufacturing defects on them but word is that TetraTec has rectified these. I had a tetratec heater once and it didn't work for long. lol
Aye, there were faults with the taps when they first came out, but Tetratec fixed the issue and replaced all faulty parts FOC. I fine Tetratec and Visitherm heaters to be the only heaters to last for me. I am trialing a Hydor, but I've only had it about a month.....Mind it's outlasted the Superfish and Hagen heaters so far...
Eheims - lovely filters, but overpriced when you consider you can buy filters made by other brands that are pretty much identical and just as good. The latest filters though are way to gimicky, I mean who really needs electronic flow control etc? lol They used to be the absolute best, but these days their new features just seem to be new gimicks rather than real innovations. What next, a USB interface for logging filter activity?
I dissagree. My two Eheims were almost as bad as the Fluval for reliability, but apparently this makes me special
Agree that electronic flow control isn't needed realy, and Eheim seem to forget that they aren't an electronics company....They build theie reputation on their pumps. Is cramming in electronics realy going to do them any good, particularly if they start to become un-reliable
That said, I can see a use for USB interfases for logging filter activity
Seriously, it would help to predict when the next clean is due. Wouldn't pay extra for the priverlage though

JBL CristalProfi - the old range are a bit simple (no self priming) but are really well built and come really well equiped with media etc, they also have really high volumes, they also come with a 4 year manufacturer warranty based on the fact that JBL are confident they wont go south in 4 years of use lol. The new e range though looks gorgeous, with all mod cons like self priming etc, and higher flow rates than the older range. JBL customer service is excellent as well, I emailed them to point out that they needed to change their website description of the old cristalprofi filters as they no longer come with the plastic lily pipe and they sent me one of their last plastic lily pipes for my trouble at no cost to me. JBL also seem to try to give use what we want. We used to want large volume filters with lower flow rates for planted tanks so we got these, now we want higher flow rates as well so they have upped the flow rates... I don't know, but it seems like JBL actually seem to care about the opinions of their customers.
I'm going to reserve judgement on JBL untill more people here in the UK use them, for the same reason that you are reserving judgement on Tetrates. To me ATM they are the unknown brand that I'd rather watch and miss out on for a while, than to use one and find it to be a lemmon.
Sorry about the off-topic-ness
All the best
