Eheim Set Up Advice Please

[michaelp]

Great link Bastbles, very interesting reading. Had my eheim running for around 5 weeks now, maybe it needs a while longer to start doing its stuff, just envious of the crystal clear water in pictures of other members tanks they've posted!

How long have fish been in. From Bastibale's link, my interperetation is that the mechanical function of your filter needs to mature like the biological side of filtration, and it can only do that with protiens in the water column. This is just a guess, so I'd wait for bastables or T1KARMANN to conirm my conclusion first.

Protiens in a tank come from the water supply, decaying matter in the tank and fish food. If you are still fishless cycling with little or no plants, with very good water source quality, it isn't enteirly unplausible to assume that there aren't enough protiens in the water to allow the mechanical filtering to start.. If you only have a few small fish, then again, protiens may be building up so slowly that the mechanical media is only getting enough "bite" at it's stage in it's maturation to remove finer particles, leaving other slightly larger particles in. If I'm guessing right, then you may just have to sit it out for now and wait for the media to mature sufficiently to do it's job

With the UV on the tank, assuming your UV unit is powerful enough for the flow through it, I'd say bacterial bloom is unlikely.

What are the current waterstats?

All the best

Eagerly awaiting bastibales' or T1KARMANN's replies

Hello rabbut, stats are , using api master test kit:; ammonia 0, nitrite 0, nitrate 5, ph 6. Fish are 12 neons, 4 glowlights, 7 honey gouramis, 2 sae, 4 peppered cats, 4 julii cats, 1 queen arabesque plec, 1 leopard frog plec, 1 tiger plec and 1 rio zebra plec (L345 I think), and 4 japonica shrimp. Plant wise, I would say average if that means anything, a huge piece of bogwood and 3 smaller pieces of mopani (hence low ph?) I probably stocked the tank too quickly, but I have lost only 1 peppered cat and 2 neons since start up (acceptable for a new set up?), and all the other fish seem active and healthy and do not seem to mind particles in the water as much as their owner. Given the above stats I probably have got the media baskets set up right but a trip to the lfs to check may be in order. Many thanks for all the replies.

Don't forget the possibility that a picture, by focusing down the overall scene and being rendered back at lower resolution when displayed on computer screens, will basically remove all the specs you see when you look at a tank in real life.

(Not to say that tanks won't have periods of crystal clear water!)

The stocking should be outputting a fair bit of protien, so assuming I'm interpreting the link correctly, the mechanical function should have started by now I'd check for media by-pass, my throwing some finely crushed flake into the inlet. If it comes out again, you are getting by-pass. If you find by-pass, swap the baskets arround, and try the test again. If you still get by-pass you will need to look further into the caurse

Just thinking....Mebe the LFS took to origional basket out to help a customer needing spares, and then put an incorrect replacement back in? Does happen every now and again... You realy need to find someone else who uses this exact model to find out for certain

A tanks water should always be crystal clear, at least mine are, and I have been keeping fish for 14 years now... Whenever you loose clarity IME there is an issue. If the filter isn't getting the floating water there must be an issue somewhere This isn't a model I'm formiliar with, and I'm not looking at your issue I person, so I can't realy say whats likely to be at fault here... Perhapse you could post images of your tank and filter set-up, so we can help more. Unless a member actualy uses this model themselves, I find it hard to see how we can offer any more advise at this point

All the best

I see Rabbut is still peddling misinformation. All filter manufactures with the execption of Hagen aim for real world (pipes media) water turn over of 1 to 1.5 of the rated tank.

for example his favorite Tetra 1200 turns over 600 l/h rated for 500 l tank.
eheim 2217 turns over 735l/h for a 600 l tank. (both with pipes and media).

Your link, Bastables, made for very interesting reading

The EX 1200 is rated at 1200lph with media, no hoses.

The 2217 classic is rated at 1000lph with media, no hoses.

The classic has more torque, so with reasonable hose length of 4ft the inlet and outlet, they'd probibly push about the same


Rabbut

You're a lier.

EX1200 is rated at 1200lph with just the motor not even mounted in the filter, without hoses without media and measured at the motor's out put, story is the same for 2217 figure.

In actul use ex1200 with media and hoses and spray bar is 600 l/h
2217 tested identically at my lfs and at planted fish forums show 765l/h. (checking my actul notes)

12 and 9 liters.... the two filters will hold this amount of water or air in total if the space inside is empty otehrwise.... it's not how much media they hold......

Keep misinforming people you know disloved organics, sechem purigen uncycling tanks and other assorted piffle.

Diden't think it appropriate to the thread, so I've PM'ed you my responce
