Crystal Clear Water

[Rodders]

Im still struggling to get crystal water.
Even with my UV steriliser.
I put poly wool in both filters yesturdat to help polish it but still there is a slight murkiness.
The black background look more lke a light grey.
I've seen it go cloudier when i've dosed Fe, but will other ferts do it as well, cause I cant think of any way of getting it clear now.

PO4 was the cause of mine. I don't have a PO4 test kit and was just adding enough for 2ppm every water change (weekly). I guess the PO4 levels slowly climbed, who knows where they were at. Check your PO4, or if you don't have a test kit, do a massive water change and hold off on the PO4 to see if your water stays clear.

Try turning your lights down. If you have 2 sets (in a series on a timer or whatever), try removing half the light. When I had it, I went from 2.4 wpg to 1.2 for 2 weeks, and It went away.

rodders, i got my eheim 2213 and coralife 9w uv on tuesday, it was all running in the evening, its saturday morning and my water is crystal clear. I don't know if my disaster (i had a regulator malfunction which spilled tons of co2 into the water) helped kill the algea with co2, but it began clearing up wednesday through thursday.

i forgot to take pictures

like pseud said get kits to test po4.

im not doing the ei dosing, i just bought mine in liquid form (nitrogen, phosphate, pottasium) along with the liquid main ferts. i use a syringe to measure the precise doses and then test with kits a few hours later. also make sure u have no carbon pads. my eheim 2213 came with one, it was said that its good to run it for about a week so that chemicals from a brand new canister get eliminated. on tuesday im taking mine out.

good luck!

Yeah, see my problem was definitely related to the PO4. Wether it was creating an outbreak of GW or the cloudiness was something else happening, I don't know.

If it isn't GW and something else, but is a direct result of the PO4 then UV lights may not help.

What are all your levels at?

no3, po4, co2, how much light is on the tank?


If the water is just cloudy (sort of a milky white), I have has succes using carbon in the filter.

 

[Rodders]

No3 is kept at 10ppm
po4 has only just dropped, first time i dosed it. Was cloudly before that though. So eventhough the levels have changed, its made no difference.
CO2, well not sure, the indicator says enough, but from the calculations and the chart I have it says too much.

The UV sterliser took all the greeness away in a few days.

Didnt know if I could put carbon in the filter as it might have soaked up the ferts?

edit - only have 1.6 WPG anyway. (big tank)
