You will see a flow rate increase by running two pumps in parallel with the same head, although in theory the flow rate should be doubled, in practice it is more like 1.5x. It is also common to use identical pumps.

Nylon stocking is fine I have used it in the past for that exact reason, and to put on filter inlets to stop shrimp fry from being sucked up!

As Ian says! It is not easy to do. But is doable with non return valves and protection systems to stop reverse flow and the pumps fighting each other. I would not bother and just run two independent filters

I like inlets that have the least restriction in flow. My eheim inlets are perfect for flow, but i dont like the colour, So i use a DIY stainless inlet with a shrimp guard. :) DIY Inlets DIY stainless steel inlets / outlets? | UK Aquatic Plant Society Filter guard Stainless Steel...

I don't like the gush inlets. Mine has not got enough slits and cannot provide my filter with enough flow, I use the obubble outlet. I like it.

You cannot add a pump inline and use them at the same time without either causing cavitation or starvation normally speaking. There are execeptions to this rule but not in home aquaira really.

Very well said. And I would like to stress again. An RO system used correctly can save water. Direct that waste water for the garden, washing car, hosing the dog down after a muddy walk. Etc etc etc.

Sorry i should have clarified what i meant by constant, i meant keep everything you do constant, this will help in diagnostics for problem areas. There is no right or wrong weather a person uses an RO system, harvests rain water uses good old tap water is a personal choice. The OP was asking...

+1 for RO-MAN. But last time I tried their site ( some years ago now ) he had ceased trading

And don't forget you can put that waste water to good use. I pass it through a second stage and then collect the waste for washing car and watering garden :)

Sounds like you are on the right track :)

I think that the key for fresh water fish is keep everything constant. You had another post asking about water changes and you where worried about the cost. I would say concentrate on setting up your tank getting it stable. And don't worry about your nitrates. If you add plants 30ppm...

I was thinking more for your high nitrates, as im sure discus keppers use RO systems for that reason. If your fixed on cost then i'm not sure which is cheapest for you sorry. Lets go over the options again: 1) Tap water (hot and cold mixed to temp) and dechlorinator 2) Tap water stored...

They can be costly as they produce a lot of waste water, but you can use the waste water wisely! The good thing about RO is that it does not matter how soft/hard etc tap water is, the unit removes everything and can produce TDS of 1-0 :D You will need to add minerals depending on your tank...

Correct :wink:

I use an RO system, This will help keep your nitrates in check and also you will not need dechlorinator. :) You can make these units less wasteful as well. I pass my waste water through again, and then collect the rest of the waste water for the garden and washing car :)

martinmjr62 I think what fox and ceg are trying to say is that without the diffuser the volume of water will be greater through the pipe, therefore turning the tank volume over faster and ditributing the nutrients through the water column :) You are nearly correct in thinking that a smaller...

people DIY clear acrylic spraybars :)

I made my own Stainless Lily pipes a while back when i couldn't get them in this country. Cost £50 in materials :)

Ive often wondered about these filters, the lcd display looks cool, but would an eheim be a better choice?

It would appear that you are right, both the 2028 and 2026 have the same part numbers for the pump head, So i have no idea how the flow rates can be different, unless the motor sizes are different, but then how can they be if they have the same part number! One for eheim to answer i think...

As long as the head off the 2026 fits the 2028 canister and is leak free then you are ok. As for flow rating, the 2028 will have a larger impellor and therfore produce more flow!

I can't remember off hand. But on the motor/filter lid there should be a label with the motor ratings and litres per hour. Take a look :)

So that he can mature the eheim without any adverse affect in water quality. This way he can remove internal filter and media and throw it away. He could of cause put the old media in the eheim. But then he would lose space for new media.
