Not too sure if crystal pro also have the colour changing resin.

Mine is the pro or the 3 stage one. If flow rates too fast, the resin/carbon will be not fast enough to absorb the impurities.

mushies can tahan the wave unless your wave is always consistant flow directing at them.

what kind?

My monti a bit pale under LED. May be need more trace elements

TDS cannot be more than 400. May be your TDS meter haywire. Our tap water isbout 40-70 TDS only. I use crystal pro for very long time already, but normally change the resin every 4 to 6 months. I use the longer life type, which a bit ex. When my water start to smell abit funny, my TDS is around 20, so time to change the resin and carbon.

They won't eat the frogspwn unless the LPS is dying. So they are like cleanup crew.

Flow rates depend on type of LPS, tank size etc. Can put higher flowrate at the top, and medium of about 4000l/h at the medium level.

My fav perc shot

Lens speed equal or more than lens size. This case 50mm, the speed should be equal or more than 1/50sec.

Not easy to open the cannister. Tried but still leaked.

Worms are ok. Try to hypo or freshwater treat the new rocks. Crabs, pistol shrimps might create some problems in future.

ya... dead prawns, a bit of urine..

I was outstation for 3 weeks. Ask my maid to top up water and clean skimmer cup. I didn't put the filter wool so no deitrus buildup.

I would suggest eheim pumps. Some used continously for more than 10 years without any problem. Jst change the impellar every few years, can already. My eheim 1262 have been running coming to 3 years now. But I have 2 standby eheim 1262 pumps just in case.

My tank is 3x3x2.5 and I am using eheim 1262. Still ok because I have lots of liverock. My liverocks acts as the biofilter instead of my sump. My sump has a little cheato farm, which is dying.. may be not enough nutrient already, CR to add some calcium to the system, pump for chiller, pump for skimmer feed, biohomes to house some bacteria, FR which I have not change for months .. I only concentrate on internal water circulation. Probably got around 20kL/hr. May be not enough.

Ok.. lesson learnt and move on. For reef tank, it is important to cycle for a period of time to get the water parameters stable before adding any livestocks.

Not sure if vodkha addition might help. Some reefers do.. Vodkha dosing info...

LED should be good for LPS. My hammer, torch, zoas, purple anemone all enjoying good growth. Invest abit more to save on the opex.

Practise and patient....

Ya la.. so unfortunate for my nanos. After many years of trying many wavemakers, I still like the cheap, ugly seio.

Whichever wins, price will still increase...

Sandbed for worms.
