1. Using T-Off from the return pump.

pros:
- no running cost
- Cheap

cons:
- insufficient pressure. Might not work properly if denitrator is slightly choke or high headmax is required.
- difficult to control consistent flowrate even with a valve attached


2. using gravity/siphoning.

pros:
- no running cost
- almost no cost
- no noise

cons:
- cannot work unless the input is higher than output
- low pressure .....denitrator choke, cannot work
- hard to control constant flowrate.
- require valve to adjust the required flowrate


3. Using a small dedicated powerhead

pros:
- relatively cheap

cons:
- can be noisy depending on the powerhead used
- difficult to control exact flowrate
- pressure might not be sufficient



4. Using peristaltic pump

pros:
- accurate flowrate
- design specially for very low l/hr
- Flowrate can be adjustable ....for certain models only
cons:
- expensive
- normally not meant for continuous 24/7 running ....easy to breakdown.
- very low flowrate if higher volume is required.
- there is a lifespan for the tube which can be expensive.
- if denitrator choke, it might not work.


5. Using solenoid-driven pump

pros:
- high pressure. Can work even when denitrator is choked.
- accurate flowrate
- higher flowrate than peristaltic pump
- flowrate is adjustable ....for some models
cons:
- due to high pressure delivery, the denitrator migh leak
- can be very nosiy
- expensive
- flowrate cannot be restricted by using valve.
- quite big in size
- flowrate delivery very fast



6. Using bellow pump

pros:
- smooth delivery
- very quiet
- compact in size
- high pressure

cons:
- expensive
- hard to find flowrate lower than 10 l/hr. The smallest is about 12.5 l/hr.
IMPRESSIVE!!

If your denitrator is tuned correctly than the chances of encountering slimy and flimy organism residue is very very slim.

after running denitrator for 3 months, there wasn't much slim when i opened it up. does it mean the denitrator is tuned correctly? output of denitrator is 0mg/l ammonia and nitrate.

If there are lots of biological activities meaning plenty of food available (carbon source), there will be lots of slime. This is especially true for carbon-based type.

haha.. so not enough carbon initially. let's see how the deniballs perform

It should not that bad because of the limtied amount of deniballs. I used to load the NR1000 with 60 pcs and choke within 1 month. Now only use 20 pcs.

Because your denitrator is 1.5 times bigger than NR1000.
