zuri08 Posted January 9, 2012 Report Share Posted January 9, 2012 i am currently running a brand new sun sun hw 302 1000/lh and a jebo 815 rated at 900l/h this is sufficient or not?i thought it would be enough but from the side of my tank its not crystal clear its kinda hazy with the floating particles any help please Quote Link to comment Share on other sites More sharing options...
Squirt Posted January 9, 2012 Report Share Posted January 9, 2012 How longs the tank been set up? I'm running a Sunsun 304 2000L/h on a 200L and it's crystal clear. Quote Link to comment Share on other sites More sharing options...
zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 a few days mate. i think ill chuck on a uv steriliser to help it along i used 65% of my original water and the rest freshwater Quote Link to comment Share on other sites More sharing options...
GrahamC Posted January 9, 2012 Report Share Posted January 9, 2012 I read that you need a filter that can do 10x the water volume per hour ie. 4000L/hour. But it also depends on what the bioload is. Quote Link to comment Share on other sites More sharing options...
Squirt Posted January 9, 2012 Report Share Posted January 9, 2012 If it looks hazy maybe add a very fine filter wool or sponge and see if that helps clear it up Quote Link to comment Share on other sites More sharing options...
jackp Posted January 9, 2012 Report Share Posted January 9, 2012 depends on your stocking level. those filters should be ok so long as the tank isn't too heavily stocked. i run 2 1200l/hr filters on my 300l tank (plus a couple of little internal filters for water movement). give it a few more days and see if it settles down.

smidey Posted January 9, 2012 Report Share Posted January 9, 2012 in my 400L i have around 50 tangs. I have a CF1000 & a CF1200 so not that much more filtration than you have. I feed a lot and the tank has been running for up to a year i guess without any issues. Quote Link to comment Share on other sites More sharing options...
zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 cool cheers smidey i was hoping youd comment on yours as i know tangs eat alot.i think its my sand that i have every time i stirr it up it clouds my tank and takes a long time to settle and when it does its not fully settled Quote Link to comment Share on other sites More sharing options...
GrahamC Posted January 9, 2012 Report Share Posted January 9, 2012 But this new tank lacks a biological filter only running for a couple of days. Even with 65% old tank water, that is not going to help much as good bacteria are not in suspension but adherent to surfaces. Quote Link to comment Share on other sites More sharing options...

Even with 65% old tank water, that is not going to help much as good bacteria are not in suspension but adherent to surfaces. once established it will be fine and to me it seems the question is related to the mechanical side of filtration as the question relates to clarity of water, not ammonia or nitrates etc. Quote Link to comment Share on other sites More sharing options...

GrahamC Posted January 9, 2012 Report Share Posted January 9, 2012 it seems the question is related to the mechanical side of filtration as the question relates to clarity of water, not ammonia or nitrates etc. My sand settles immediately so perhaps it's dirty sand? Although if this is a new tank which has not cycled it could be a heterotrophic bacterial bloom. Quote Link to comment Share on other sites More sharing options...
zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 its not cycling as i have used my old water my old filter with media and the sand which is supposed to be silica but its not whites a grey and stirs up way to easy should i replace the sand with something else because it goes super cloudy.should i up my circulation?

Although if this is a new tank which has not cycled it could be a heterotrophic bacterial bloom. it could be but i expect that the sand wasn't rinsed properly. i am currently running a brand new sun sun hw 302 1000/lh and a jebo 815 rated at 900l/h this is sufficient or not?i thought it would be enough but from the side of my tank its not crystal clear its kinda hazy with the floating particles any help please i think that filtration will be sweet on the 400L tank. Rated 1900LPH on a 400L tank is nearly 5 times the tank volume per hour. I have rated 2200LPH on a 400L tank and it is plenty. just make sure the filter pads are up to the mechanical side of it and I am sure you won't have too many issues of clarity once the substrate is clean. I believe the substrate does as much if not more biological filtration than the filters do so have always had a good layer of substrate.

zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 ive just got water flowing in from one filter no spray bar on it and on the other i have a spray bar pointed down at the water and a 1200/lh powerhead but i will get a wave maker fro mine this week i also just realised my mechanical wasnt very good didnt have any wool stuff so i put in some i think that should help it out.cheers for your help smidey what length is your tank Quote Link to comment Share on other sites More sharing options...

I have silica sand from Placemakers and I don't have an issue with clouding ....though I thoroughly washed it first. And yes, it's not very white ....

GrahamC Posted January 9, 2012 Report Share Posted January 9, 2012 I believe the substrate does as much if not more biological filtration than the filters do so have always had a good layer of substrate. I think that is contrary to what the experts say. The surface area of a sandy substrate is not that great compared with your standard noodles, and pot scrubbers. I see pockets of gas developing in mine indicating anaerobic metabolism. Now, if you fluidized the sand, that is an entirely different matter :smln: Quote Link to comment Share on other sites More sharing options...
zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 its definetly not silica sand that i have and i always was my sand before use of course but this one was washed for atleast half hour and put in but still always clouds up so must breakdown in the tank.do u recommend an extra power head smidey my tanks 120 60 60 have a 1200 l/h already but will get a 2400 l/h off tm?

GrahamC Posted January 9, 2012 Report Share Posted January 9, 2012 you could just take some sand out and wash it to see if it clouds the water .... Quote Link to comment Share on other sites More sharing options...
zuri08 Posted January 9, 2012 Author Report Share Posted January 9, 2012 ok good idea graham ill try that now noticed an immediate differnce when i put more spong/wool in filters Quote Link to comment Share on other sites More sharing options...

Now, if you fluidized the sand, that is an entirely different matter :smln: the substrate used to be the filter before canister etc, i doubt that just because the flow of water no longer consistently passes through the substrate the bacteria would no longer live in it. the africans are great at turning over the substrate so there are very few gas pockets in the tanks i have kept and the white marble chip i have for substrate is always very clean. it is all good discussion on our theories. do u recommend an extra power head smidey my tanks 120 60 60 have a 1200 l/h already but will get a 2400 l/h off tm? not for a 4 footer, the spray bars will make plenty set up right. a powerhead will be to much.

Sure, bacteria will be there ...just not the ones you desire. The fact that you do observe any gas pockets indicate that you have significant populations of anaerobic bacteria present ... And in pre-filter days as in China 700AD, they did frequent water changes to keep the fish alive. Quote Link to comment Share on other sites More sharing options...
