Hi All JPCW system

Hi,


Considering it is 40,000L and only 20 fish and a few marron there shouldn't be too much nutrients.
That'll teach me to acquaint myself with the basic system details before I post.

With 20 fish and what's left of the marron......in 40,000 litres.....I wouldn't worry about anything.....including the algae. It will right itself eventually.


All the info on the UV lights specifically say that it does not do any major harm to the good bacteria which is supposedly concentrated in the filters and on rocks etc.

Researchers like Dr James Rakocy have been quoted as saying that up to 70% of the bacteria in a system is in the water......but, once again, with 40Kl of water it's not likely to be an issue.

Hi John,

Thats great news. I got my gravel, got one GB on-line as 2nd one has a crack in it, so going to line it with pond liner!! Got everything running now so cycling has started. I have 3 red claw and about 100 guppies in the sump, dont care too much if I loose them, but shouldn't. Calculated that I have about 1100L going through the system, so enough room to buffer, 2nd GB will add about another 200L.

If you think about the UV light, nearly all Koi keepers use them after the filter and their water is clear as...
All the bacteria is still in the filter doing their chemistry there. Sure hope it clears up.

Took about a week to see any difference but now it is starting to clear noticeably each day. Running the pool pump 24 hours is probably also helping but mostly the algae seems to be settling to the bottom of the pool now. I can actually see the marron every now and again, the fish still seem to be hiding somewhere down the deep end where I can't quite see them.
