Wys ons bietjie van daai korale!!
I found an old Jebao rw range power supply and now the mp 10 is running at the back of rockwork to try and stop detritus build-up.
So i tested my water for the first time now after a few weeks of running.
NO3- 50ppm (result of me collecting water on a bit of a stormy day)
PO4- 0.08ppm
Ca- 420
Mg- 1440
dKH- 7.6
Any advise or remarks

ThanksThose euphyllia are very pretty!
Ill definitely keep that in mind thanks. Thats why i dont run to much of it at a time. Ill keep testing to keep up with the reduction they cause. Im also leaning towards the second skimmer but @qball said he can maybe build me a reactor with a venturi pump. Whats your take on that?I used to run them in a reactor with a normal powerhead with a venturi. Worked very well but power failures were a problem. Then i also ran them inside a second skimmer. This was probably the best. But be careful with cubes. They work exceptionally well and you run the risk of stripping all the nutrients out. This was my issue as i had a light bioload. That was one of the contributing factors of the death of 90% of my corals.
I have a generator on the farm so that kicks in. I want to use a bubble magus reactor with the pump sitting underneath. Just saves space so turn that pump into a venturi pump with needle wheel impellerWhy do you need someone to build you one? You can use a normal fluidised reactor and use a cheap pump with venturi. Most of the fluidised reactors should be able to take 1.5-2L of cubes. Just add it to battery backup.
