If your tank is flourishing and you have no algae and both Fish amd Corals are doing well. Do you need to keep on testing your water .If you have  an established tank surely by looking at it you would notice if things where not right?

I understand the concept of catching things early. But if you are changing water frequently and the salinity is stable surely you are OK?

I'd agree , I still test my salinity alk Cal and mag regularly  just to ensure I don't need to adjust my doser a little , otherwise I feel my maintenance deals with the rest . I suppose it depends on your methods , the less water changed = more measurements and dosing required I'd presume.

I change my water every week without fail. Over the years I have had to overcome every mistake you could possibly make, be it from algae to high salinity to almost cold water. with not only my fish but  corals. Somehow my fish survived the corals not so much. In that time  have also tried just about every magic potion available and spent £1000s .

As I mentioned previously about 6 months ago I was carbon dosing and it wasn’t getting me anywhere. I decided enough and let my tank do it’s own thing I decide to do weekly water changes of 15% invested in a few more CUC. After a few weeks the tank suddenly sprang into life the Fish were active and I started to introduce a few LPS and softies. All of these are now flourishing and showing good growth, without any dosing. I have just started to add SPS and this is where I may come unstuck as theybneed a little more TLC with parameters. Anyway I am happy with my tank now after a long battle and I check it regularly. I know when something is not right and haven’t done any checks apart from Salinity and even then Nitrate 15-20ppm was the last reading about a month ago .  I know it’s high as I feed heavily 3-4 squirts of various frozen and a few sheets of Nori  - sometimes more I don’t bother how much I feed really. I know thimgs are going well as my Clownfish are packing on the muscle so to speak and have grown rapidly ( proper Storm Troopers when it comes to  feeding time)  I think they would take my hand off if it was left in to long, more than likely they would eat out of my hand 😀😀😀😀😀

I am not saying it is the correct thing to do I am merely asking iif its so wrong ?

I got a bit lazy with my tank and stopped testing.  First I stopped testing salinity and phosphate because they always stayed the same, then gradually stopped bothering with cal, mag nitrate and alk.

Everything looked okay for a long time (months), then suddenly I got corals stripping at the base.  When I did a water test, the salinity was 1.030, the cal over 500 and the alk under 6dkh!

Thanks:

Oh, maybe time to start again - most of my test kits are now  out of date and my Hanna kits are like the days of the week always changing results that I can’t trust them - the slightest variant maybe where you put your finger or whatever reason it thinks can throw it onto a fit . For example 1.8 Pppm on Hanna LFS 0.01 !!

Yeah I'm having a nightmare with this and my salinity measurement at the moment. 

Bought three different calibration fluids,  all totally different readings.  Thought maybe the refractometer had gone Pete Tong so I bought a Hanna Salinity checker for £80 which comes with calibration fluid.
Result: i now have 4 different salinity calibrations, no idea which is the right one! 😂👌
