Sps frags from a tank with scary parameters.

Just some background.

Got a few monti frags from a freind a while back and couldn't keep them alive longer than 2 weeks as while my levels seemed fine and wasnt doing wc something was amiss.

I started with some nsw wc from our local aquarium which provides sand filtered seawater and noticed an improvement in some lps that was just hanging on and have just added a few more euphyllias that seem to be doing well.

My levels are as follows : kh 9, ca 420, mag 1380, nitrate 2- 5, phos 0.09 phos was down to 0.03 about 3 weeks back but have been feeding a bit heavy and also experimenting with fuel. Ive been trying to gt my kh to 7 to match our nsw and have stopped adding kalk to my ato. So will allow a gradual drop then maintain with RHF DIY 2 part. I use about 1.5 cups of ati gfo on a 520lt system currently and trying to change out every 4 weeks. Ive started to gt a handle on y tank and want to give sps a shot again. Im currently doing a 140lt wc fortnightly. So.....

I got a few test sps frags from that same freind and was curious to test his water and this is where it gets insane. His ca was 425, kh 4.2, yes 4.2 had to measure 2 times, phos 200ppb max readout in ulr checker so could be higher than 0.6ppm and nitrate about 50 yet he has good sps growth and ok color. The montis are a deep red and green and he usually just does a 1000lt wc every month using nsw from the same source as me. He basically pumps water into his tank whilst the sump floqs to waste so not a 1000lt change. His system is about 1400lt. No buffers are uaed not ecen kalk. He says he hasnt tested in 2 yrs and usually goes by the look of hia green monti to tell him a wc is due.

Will the move of those frags be ok or will the sudden jump in parameters be fatal to the sps? These are all freah frags just broken today of the colonies?

How important is parameters of receiving tank cos im looking at adding a few more corals if these do well from other reefer's but have no clue as to what there levels are without asking ir testing myself.
