I now have cuc, corals and fish - my testing today is:-

Ammonia  0
Nitrite  0
Nitrate 5
PH  8
Phosphate 0.25
Salinity  1.026
Temp  26.8

I am feeding frozen mixed reef food (defrosted) and also have live plankton food.

My nitrate, PH and Phosphate levels seem to remain the same each testing - I am due to do a water change tomorrow (I usually just change 10L from my 95L) my nitrates did reduce last time so I hope they will come down a bit then.

Do these look about right?  Anything else I should be doing / adding / testing for?  Also, I have no carbon in, should I?

Thanks

Hi, your P04 is on the high side, is that the API test kit you use? Also it's best to rinse the frozen food with RO water before feeding as it's loaded with phosphate. Carbon helps take impurities out of the water and cleans it but dosen? remove phosphate. You can try a bag of rowaphos in your filter or if you have a sump you can also try a reactor to run rowaphos or take out more water to dilute the phosphate in water changes. Lots of ways to do things :)

The phosphate is 10 times what you want.  The nitrate is ok, but would be better a little lower.  The rest looks spot on.

If they're not rising, that's a good sign.  Water changes will then bring them down, and the tank should maintain itself.  Water changes may then be optional (lots od debate over where you should/shouldn't if nitrate is in check). 

Carbon is optional.  Again, there's debate over whether you should run it all the time, every so often, or only when there's an issue.

Re. water changes and carbon, do a search on here and you'll find a few threads discussing this.  Jump in with any questions you have.

Thanks - I have a Nutrafin PO4 test - there is only 0 (white) and the next colour is 0.25 - the chart goes up to 5 with 6 colour blocks.  My test is between 0 and 0.25 so not sure what it is exactly - I will order a more accurate (Salifert?) test kit.  Why do they produce a kit that jumps from 0 to 0.25 if that is 10 times more than it should be?

Rinse the frozen food - how do I do this?  Rinse the frozen cube?  I am only using 1/3 cube at a time.  I currently defrost it in an egg cup with tank water.

Thanks

Just rinse the defrosted cube in a net before placing the net into the tank to release the contents.

Thanks - so which is the best phosphate test kit to get?

I defrost cubes in a cup of RO water then tip the defrosted food into a siv then rinse with RO water probably a liters worth then flush the food into a tub. Then feed via a turkey bastor a squirt or two. I keep the tub in the fridge to keep it fresh. Lasts a couple of days. ELOS is a good phosphate test or the D&D one.

My phosphate test kit is mg/L (ppm) and says 0.0 - 1.0 mg/L (ppm) is ideal phosphate range so on this basis my 0.25 is good??  I am so confused  :O

buy why does it say 0 - 1 on this test kit is ideal and only tests 0 - 5??  I will get a new test kit but I just don't understand why it says it?

Ah, that's a high range test.  You need a low range test.

Like this, which does both:

ok thanks - can you just explain that in simple terms for me? - so I have a high test kit - does that mean it only tests for high levels which you would use if the readings did not fit any of the lower level readings?  and why does their instructions say 0 - 1 is ideal?  If I wasn't on this forum, I would be thinking my water tests were perfect!

This was my recent test for Phosphate using the D and d kit. I added some rowaphos yesterday which I hope will help reduce it?

yes that is the kit I have just ordered - will be interesting to see what my results are with that (or not!)  just don't understand what Graeme said about mine being a high test kit and why the lfs just sold me that one and the instructions say 0 - 1 is ideal????  Going by that, I would have carried along quite happily not knowing I had really high phosphates - well until my tank started looking ill I guess!

@Debbiem Yes, the high range test is for higher levels of phosphate.  We want very low levels in our tanks.  I'm not sure what the deal is with freshwater, but that test kits says it covers both.

I go off this for ideal chemistry in our tanks:

@Adenium Phil Be careful comparing colour without using the comparator.  It'll darken the colour quite a bit.

Here's the D-D instructional video, which is long and dull, but worth watching to make sure you're getting accurate results:

I use Elos very easy to read and mines a steady 0.015 which I'm happy with :)
