I currently have a 6 x 2 x 2 tank with a sump filter I bought secondhand, it came with no instructions of course.
After a few mods I think I've got it right, but would like to know if anyone can suggest any improvements or glaring mistakes I'm making.
size is 1300 x 460 x 360 and holds approx 200 - 240 lt.
Have used my skill and the bosses time (took ages - lol) to draw it up with paint.
Flow rates are only guesstimates.
Come on someone knows about these things!
I spent a lot of time po that drawing, at least tell me it looks ok. Lol
way too much dacron, you want a small sheet for fine filtration.
put a sheet of dacron where water comes in add more media bio balls ceramic lava chips what ever you like to where the dacron is.
re circulating pump is a bit of a wast of time just get more flow through the tank for a 6x2x2 ~650L try and get 1300-1800L of flow through the tank.
Ok so would swapping the noodle and dacron around sort that part out? I've got buckets of those blue 25mm bio balls in the shed. And then a better / bigger spray bar and pump to fix up the other end.
Flow rates were only a guess, return pump is an eheim variable flow thing - have seen 3 different models of the same looking pump on the net. Will get a bucket and work it out properly.
Thanks for the advice :) will let ya know how l go with the mods
the eheim pump you talk of is a 5000 litre per hour unit. Imo not enough for your size tank. I would go for an aqua medic ocean runner 6500
Have looked it up it's an Eheim Compact+ Wet / Dry Pump, but the model number could be 2000, 3000 or 5000. Nothing written on it to indicate which one. The dimensions are all the same. Guessing its the 2000 coz the flows way too low.
Looks like a shopping trip for me.
Changes so far, still waiting for new pump.
Bio balls removed frim intake, intake tube raised, added coarse sponge mainly to stop small fish from finding out whats on the other side.
Dacron as per pic.
Approx 30+ lts of bio balls in second compartment.
Ceramic tubes approx 10lts in next compartment.
thimking I may need something in with the bio balls to move the water around a little, air stone or small powerhead pump. Any thoughts?
perfect if you like add an air stonre with the bio balls and ceramic, but you dont need it.
id iuncrease your pump a little to somethimg like an eheim 1260/1262 more head height hence more flow from bottom to top
Some of my sumps, These things work fantastic at keeping water crystal clear and I never have a problem with any of my Parameters.

Bio Balls are only effective when used as a Wet Dry Media and should never be fully submerged in water
