HELP with Flow - 30 gal mixed reef. Are my corals getting hurt???

[davy31]

Hey guys, I'm running a 30 gal mixed reef with 3 Tunze wavemakers. As seen in the pics, I've got 2 Tunze 6015's on the back wall facing the front glass aimed towards the surface to get a choppy agitation and a Tunze turbelle on the side wall aimed across the length. In total I think it about 1600 gal/hr turnover.

As I'm have cyano and diatoms in a 10 month old tank, I added the turbelle and reconfigured the flow pattern. To have a bit more irregular patterns in the middle and lower part of the tank.

However,diatoms are on the front of my sand bed, some spots of red cyano on a few rocks . I don't want to hurt my corals with improper flow patterns, especially the torch and frogspawn in the front of the rockwork.

Any advice on how to optimize the placement and pattern would be really great, Incase my current setup is hurting anything. My nitrates are at 12 ppm, phosphates 0.05, pH 8.2, Alk 9, cal 390, mag 1280. The parameters are fairly stable with fluctuatione in calcium seen the most. I dose Redsea Reef energy AB+.

Also, my tunzes are the non programmable kind.

Ive heard Redsea Reef energy AB+ is like fuel for cyanos and especially dinos.
Are you using RODI water?

Btw. I think your flow is pretty heavy as of what I can see. Especially when there is mostly LPS

*allenfalls braucht es die turbelle nicht wirklich, du hast ja keine heavy SPS wie Acros die viel flow benötigen wie ich sehe

I actually had cyanos and dinos since the last month and the AB+ was started only last week.

My water records 0 TDS. I did a water change last week and find that water changes sometimes exacerbate the algae growth. Weird I know, but I've seen this happen on multiple occasions. I spite of 0 TDS RODI water a decent saltmix from the microbe lift brand. I've used Tropic Marin and Red Sea and they seemed to have the same effect.

Also, my tunzes are the non programmable kind.

Even non programmable power heads can be put on timers. If you want more sway in the tank.

Does the constant on and off function in the timers affect the motors of the tunzes?

I don't know about tunze personally but being a big name in the industry, I would think they would be fine.
