Nitrates

I have had my 40B up and running about 6 months. I have about 40+ lbs of LR and a sand bed 2" deep. I have 20+ hermits,12+snails, 2-small true percs
1- pygmy angel 1-yellow clown goby and 1- yellow eyed Kole. I have a HOB prizm skimmer and a marineland 400 powerhead. I can't seem to get my nitrates to stabilize. And they are always in the 20+ppm range. Help.

check your water that your using to do water changes with. I know it sounds dumb but if theres trates in the water that you are putting in the tank, then youll NEVER get it under control

How often are you doing partial water changes and how much?

Anything more than 10ppm in salt water is Bad to say the least.

The 20ppm isnt optimal of course but is not as horrible as people may think. I dont see that you listed any coral so the 20ppm is almost acceptable. the goal of course is to have zero but in a fish only system it is common.

I would do several larger water changes and see where you are at from there. Once you get them lower they will be easier to stay on top of. I would even say to do a half tank change if you can, I tend to do 50% water changes on most of my tanks with no ill effects. Just make sure salinity and temp match and even check the ph so you dont shock your fish.

From there I would limit my feedings...Do you use frozen food? If so do you rinse the food before adding it to the tank? Might be a good idea to cut back on the nitrates. In addition, if you have any foam blocks or anything be sure to wash them when you change the water in old tank water, nitrates can linger and never seem to go down if thats not done.

Hope that helps a bit. In fought never ending nitrates in my biocube only to realize that they were never leaving the tank and were in the filter media bags I keepin the tank. lol

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

this isn't completely true. there are very successful, well-established tanks that have 10+ trates consistently

Whether theyre having sucess it isnt really particularly fair. So it isnt sucess imo.

Well then I guess my years of reefkeeping arent successful? There are nitrates in all 9 of my tanks to some degree or another. I have yet to lose a fish over nitrates nor do i expect ever to. While it is not a perfect thing to have nitrates in the range that the OP does we shouldnt be here condemning him for it or telling him his tank isnt successful. Really now.... Saltwater is a lot different than freshwater and there are so many variables that contribute to nitrates. The OP wants help in getting them lower, no one here is telling him that its good but that its expected and not the end of the world.
All the advice posted has been positive and everyone totally understands the situation and wants to help. Just want the OP to understand the issue and see if he can improve the conditions. And as a side note, if it is indeed a fowlr only then the nitrates are not really harming anything and at the level indicated should not harm his fish to any extent that it would be "cruel" or "mean"

I am done. lol
