Ceramic rings are for colonisation of bacterial-filtration (IMO). Inlet sponge works well (over inlet strainer, in tank) and is easy to clean, without breaking into the cannister :D HTH, Cheers, Mick B PS, The thin pad, I buy large pad of Koi matting, cut to size and split-off a thin...

:wink: :) :) :)

Hi Matt, Just a thought, the inlet pipe size of the pumps may be the determining factor? If you are tight for space, to get 2 inlets and 2 outlets into the tank (bl**dy brace bars!) then you may find it's the size of the biggest inlet which will fit, determines which pump. No point in getting...

Hi Matt, The choice is yours! :D But IMO I would go with the additional 2000 ltr unit (but that's just IMO :oops: ) This may not suit you, but I find, when checking the flow patterns, a few drips of malachite green or meth-blue can help :wink: Cheers, Mick B

Hi Matt, The pumps will compete, and dependant upon which way around, filter-load etc, and they may even cause cavitation (not good). Also, most cannisters have pipe and fittings, to match the impellor output, so you may not see any improvment at all! So IMO, (I have similar) put them on...

Thanks Jay :D Since starting EI, my Java fern is having babies (plantlets on leaf edges, not sure which veriety it is??) but looks like I will also have some plantlets to re-plant sparce areas etc :D Cheers, Mick B

Thanks Jay, Have java fern & anubias on wood, I did have bolbitis, but it died back?, however, since using EI (only 2 weeks so early days), the J-fern & Anubias are starting to re-grow, so once they prove stable, I do intend to re-try some bolbitis (Have you any spare? :wink: ) Cheers, Mick B

Hi Aaronnorth, Understand and appreciate your comment, but like life, it's not quite that simple :) Areas of the UG are not deep-vacced, only surface (1/2") vacced and loaded with flourite, other areas are deep-vacced (up to 7" deep pea gravel to 1.5" pebbles) but no plants are rooted in...

Thanks Guys, I'm ok with how, it was what I was trying to achieve 8) I think I'm OK with circulation as I rotate the water around a vertical axis (external pump & heater) back via nozzels just below surface, plus the action of 21 Discus tend to stir things up a bit :lol: Plus the U/Gravel...

Hi All, Very new to this, so sorry if it's a dumb newbie question :oops: , but; I have read on varied threads about circulation to distribute ferts etc and they seem to suggest x 10 But, I also note, lots of surface aggitiation de-gasses C02, so I'm looking for calrification please; As I come...

sory don't know how to edit??????????????? should read (22 x 22 x 3.142)/4 = 380 mm sq :oops: Now found the Edit button!!! As I said NEWBIE!!!! :lol: :mrgreen:

Hi Chaps, Not wishing to be 'clever' (as the newbie0 but the statement re-flow is correct, but the figures are off by a factor of 4 16mmDia has a cross-section of (16x16 x 3.142)/4 = 201mm sq 22mm Dia has cross-section 0f (22x22 x 3.142)/4 = 380mm sq But the advice re plumbing is correct...
