Feeding - what and how much?

So, we have a hawkfish 3 inches, a six line wrasse 2 inches, a tail spot blenny 1 inch, a pygmy perchlet 1.5 in., a mandarin goby 2 in. and a target goby 1.5 in.

Tank is 55 and water parameters have been good with the exception of high nitrates repeatedly. Have a 10 gal fuge and found that we should be using a more powerful light on it [it had not gotten dirty very fast and have had some algae in DT.] Now that we got a powerful light [elite helped with this] and have left it on it is quickly getting to be the mess we want.

Yesterday with high nitrates and little confidence in my API test kit, I took H20 to Elite. They found the same problem with I beleive a Salifert kit? [pink rather than red]

So, I have continued reducing food. I give a slice of marine cuisine and husband watches time for 2 minutes.

We did 3 water changes 10 % in 4 days last week still getting high 80 + nitrates, then yesterday did a 20% and added Start Up, and Prime and have a nitrate reducing filter in the fuge since nitrate went up again last week and verifyed with Aquamart though their kit showed lower - still problem nitrates.

Today, nitrates are 40 ppm on the kit I don't really trust so I will schlep some water somewhere to verify.

Ooh, and in terms of food I had created a "pod environment" in the tank [small piece of filter, chaeto and rubble on top. I have added Alagae Barn's pod mix to fuge 2 weeks ago and and put their ocean mix in fuge each a.m. Mandarin and Target [target eats some regular food too] are both round and show no sign of starving. Thought I had better give the full picture.

Snails and crabs are okay and crabs growing from prior over feeding I am pretty sure.

Have used Marine Cuisine, Mysis at times and Phyto feast [stopped everything but small amount of 1 frozen food 2 x daily.

So, I sit here wondering whether to get a new test kit of another brand, how much more water changing and if I am still overfeeding. Blenny is smallest and newest and he is no longer doing okay. Now stays on bottom of tank, and I was aware that the nitrate may cause a causualty. I hope he lives.

Sorry for the novel, but wanted to try and give the whole picture. Everyone else seems to be thriving. I stopped target feeding except once weekly and keep that minimal - and will not do that at all until we resolve this.

Other forums have several posts about nitrate probs and seems most feel that other test kits are better.

So, 1. how much would you feed the above group, 2. what would or do you feed, and 3. would you do anything besides continue H20 changes. 4. What test kits are best? Lots of coral and most seem okay but not as lively as they had been.

Any thoughts appreciated.

This will take some time to turnaround. How old is the tank? Your bacteria should eventually start to filter out the excess nitrates...but this does take time to occur.

I would continue with weekly or even bi-weekly water changes of about 20% and see if your levels drop. For additives I would look at something like Seachem Stability or Microbe-lift Special blend...I've had good luck with the latter reducing nutrients in my tanks. Are you running a skimmer at all? It sounds like there just isn't enough nutrient export in your system right now. Since the fuge will take time to catch up and start bringing nitrates down, you can also try added some live rock from another (trusted) reefer's healthy tank to diversify the bacteria in your tank.

Other than that, just continue what you're doing; you're on the right track. I'd opt for feeding relatively clean frozen food...meaning nothing that has too many small particles that float around and are ignored by fish (eg mysis) and make sure that you drain off the excess water after thawing the food.

Thanks, this makes sense to me. I forgot to mention that we are running a skimmer in the fuge and it seems to be working well. Funny you should say to drain the water when the food melts - I had been target feeding zoas, etc. with that and so putting it all in the tank. I have stopped all of that for now. Sounds like time to keep changing water and let the refugium shift gears.

Appreciate your thoughts on this.

How often are you harvesting from your fuge? When I got lazy and stopped taking half my caulerpa (I use cheato now, but didnt then) out every week and waited a month once, my nitrates went up from almost undetectable to 20 ppm even though I was doing the same water change and feeding schedule.

We have been doing it based on volume [i.e. having too much] which never happened as we just got the right lighting, and removing any die off. I had not heard of weekly removal as part of the process.

granted I have like 50 watts worth of leds and pc lights over my fuge, i find that if you take half out every week and then stretch it out to give more vines exposure to light every week, I minimize nutrient level while maximizing weight harvested. dependong on light and other factors, the exact length may be different for you.

Well, this took me on a lengthy research project - thanks for bringing this up Z. I read that most often 1 time per week is what is recommended and our fuge has quickly become filthy and growth is amazing so with water change today will begin dealing with macro in fuge. Nitrates still showing somewhere between 40 and 80 on API test and this is many water changes later. Algae bloom in DT has increased, but had not been what I would consider huge. The only thing we know for sure this a.m. is that we both feel stupid about this hobby.

No need to feel stupid, take a look at pics of tanks from 20 years ago and see how much the hobby has progressed...it's challenging for everyone at home point or another. :)

Keep researching and learning...and don't get lazy on husbandry...ever. It's amazing how quickly things can decline due to neglect and how loooong it takes to get the tank back in line.

Thanks jahmic. Yeah, it is funny, this a.m. we realized our duncan had split during the night and 2 are sitting there - and given the amt of time we stare at everything that was a surprise. It is like no matter what probs this hobby throws at us it is smart and seductive enough to throw us a bone and give us some other reason to keep going. Live rock has nicer coralline every day...frags are growing, so it frustrates me as I have even been reading "advanced aquarist" and trying to look at a wide range of credible research, it seems to be always something :)

We are competitive and like a challenge!
