Cheers!

UV sterilizer did fix my issue. I was losing without it.

Happy it helped you. Fingers crossed it will help me too.

BTW, I finally got sodium metasilicate. I will dose 1ppm of SiO2 today to spark diatoms. But I need silica tester, doesn't sound right to dose without measuring.

Edit: I just bought Hanna Silica Low Range HI705.

Why didn't you tee off the UV line using the return manifolds instead of tapping in straight from the return?

Why didn't you tee off the UV line using the return manifolds instead of tapping in straight from the return?

A few reasons:
- Wanted all the return water to be treated.
- Don't exactly like the idea of treating return water and spitting it back upstream from the return pump.
- The unit was not plumbed at all, and as I am to rebuild the whole return piping, I was not inclined to make a permanent installation. I don't like how CADE designed all the plumbing. But I have OCD.

You need to be able to adjust the flow thru the UV via ball/gate valve or a separate pump, the flow thru the UV is minimal compared to your return flow. I can't see how this can work, but I have seen others who have plumbed the UV output water directly back into their displays.

This is a Jebao DCP-10000 pump with a controller. The flow is set to circa about 2,000 L/h. I probably should take the effort and measure it properly.
Water movement in the tank is done by 2 Jebao GMP-40 wavemakers working at about 50-60% power.
