Problem

ok I will try to slow down on the feeding. Thanks for the tip.

The longest I feel comfortable with not feeding rays is a day or so. I feed mine every day.

Have you looked at any of the threads for drip systems?

 

[JamieC77]

no, not really, I don't know much about them. I will look though.

Depending on location of the tank, they can be very simple. That would eliminate your water change issue.

As far as the purigen goes, don't rely on it. While it may reduce nitrates we have no idea what it does for other harmful organic compounds that we can't test for.

you can also look at changing a little more water.

20 gallons per week may not be sufficient on a 120 with messy fish.

I change 35 gallons per week on a 90 for example, because I too have big messy fish.

Good point. I change 50% each week in my 125 and 75. 20% a month in my brackish 29.

I looked a little at the drip systems, they seem really hard to set up but I will look more. I will try doing larger water changes but 50% is a lot that is 60 gallons!

They look intimidating but they're quite simple. I may draw a few block diagrams to explain it if I have time

 

[JamieC77]

That would be great if you have time, no rush.

Yes, but you get used to it. it brings down the nitrates, so it's worth it.

i also change about 50% of my tanks' water every week. nitrate at 20ppm, good enough for now. Emperor bio wheels are one of those filters that do produce alot of nitrates as result of the filtration action. If you want, try looking up nitrate reducing filters on the search function. It utilize bacteria that don't use oxygen, but sulfur compounds to turn the nitrates to nitrogen gas. Can be pricey though. the other way is to use a w/d system with plants in the sump but you need to have a strong light source continuously on for the plants to take up ammonia and nitrates.
