For All You Juwel Owners With A Juwel Internal

[MermaidMel]

I've always hated internal filters because when you remove them from the water they leave crud behind, so for that reason alone I would opt for an external

im going to opt for an external on my 125, how do you prime them? what is it? bedding in the filter?

boboboy you ever had a juwel?

i dont know how anyone can say the filtration is crap, they filter well, and the filter on my record 60 has coped with over stocking very well (no ammonia or nitrite spikes) how can anyone say there crap when there the biggest internal filter on a tank that size, and can cope with big bio-loads

yes i have, its now in the corner of the garage, as i would not pass it on to anyone. i used it for six or more months.(i bought a mature tank, 2 years mature, and stock) i too was happy with its work. at the time, i didnt know any better. a cannister came up, so i bought it. the difference shocked me! mind you, the addition of a second cannister last year, took the tank on even further!

so yes i am talking from personal experience!

good lol just checking, i think i will go external eventually. could you answer my Q, on externals??

5x turnover is now considered a good rate for healthy fish.

if you want to increase flow, how much does another power head cost?

sorry to hijack question 5x turnover, so if you have a 200 litre tank, you want the filter turning over 1000 litres per hour?

that qoute was from boboboy

ahh its not just the flow. i think someone mentioned "dwell time" (the period of time the water is in contact with the bio media) you need a large bio area to increasee flow. so adding another pump, could well, make thing worse. but it might improve machanical, but at the disadvantage of Bio.

yep, thats about the size of it. you see the figure around, whenever filtration is talked about. if the search were working, you could find any number of posts here, on the subjet. mind you, you hear of 10X being touted too now!!!!

no i mean not a stronger power head for the filter, but a separate one to put at the other end of the tank like i am in my planted tank

Mine is 6X but could handle more, its not some crazy flow that the fish can't cope with, only i'm happy with my set up and don't fancy spending more on it just now lol

ive got 12x and will have 10x on my new planted tank.

12x is loads whats the tank vol and whats the flow rate (just being nosey)

 

[Truck]

60 litre, 1300 litres of flow, quite densely planted. i know its alot

PMSL yar I thought you said you were going to reduce it to 400?

 

[Truck]

no in the new tank im reducing filter flow to 400 LPH but tank flow (water movement) will be at around 1250 LPH for the plants,

its important for the filtration pump to be slower for better filtration ( the water inside the filter is unaffected by water movement in the tank, hope this makes sense

no in the new tank im reducing filter flow to 400 LPH but tank flow (water movement) will be at around 1250 LPH for the plants,

its important for the filtration pump to be slower for better filtration(longer contact time = more efficient filtration!) ( the water inside the filter is unaffected by water movement in the tank), hope this makes sense

OMG its another one of those complicated hardware things I don't understand!! How do you reduce the filter flow to 400 but keep the tank flow at 1250?
