Took over 4 years.. but back in the hobby :)

My RODI is a 0ppm courtesy of the RODI unit I won at Frag Farmers Market and measured by TDS meter bought on Amazon recently. Also.. haven’t tested CA and Mg as color and growth (unrelated but polyp extension) have been great. I do have test kits, just reluctant to crack them open.

What is your setting on Hydra 26HD?

I was setting it as follow and my corals very happy.

Start 3pm to 9pm with ramping 1:30
Total 9hrs

UV 9
Royal blue 116
Blue 100
White 15
Green 5
Red 7

Never had any issues. So, I don't agree you blame on the Hydra 26HD LOL...also, try to use "Chemipure Elite" that might help your cloudy water to clear up. I always used it on my system and replace every 3 months.

I’ll test Ca and Mg when I get home today. I’ve done 4 huge (10 gallon) water changes in the last 2 weeks. I mix, let it sit over night with Powerhead and heater. Match temp and salinity. It is always clear when it goes in. Does that rule out precipitation?

I don’t really think it is the hydra... it’s just wild timing if that makes sense. I just did the “easy setup” and have lights on from 1-9 with a 2 hour ramp. It has been in acclimation mode. I had it set to finish acclimation mode in a few days.

I’ll get some chemipure elite..

Thank you guys for working through this with me!

That def looks like a bacteria bloom in the water column, I've had 2 and both went away before I had to buy a UV sterilizer. Something probably went out of wack in the chemistry and the population exploded. If you have a skimmer you should be fine, but if not I'd maybe add an airstone so you can get more O2 in the water as those guys can suck it up fast and lead to hypoxia
Something is blooming in the water column. See if you can borrow/buy a uv sterilizer and that should clear that up.
I think yall are right to try the chemipure then consider a uv sterilizer. I don't really want to go that route tbh.

Another reefer suggested a round of Clarity.

@Aquanaut... I really thought it was bacterial. It's a relatively new tank, although I did allow it to cycle slowly and naturally.. it can be part of new tank syndrome. Fish seem fine though, not bothered at all. Also, I've been reading and 10 days is a very long long time for a bacterial bloom. This has been a few weeks now. In fact.. I messaged a fellow reefer friend on June 12 that the tank is driving me nuts and I'd just done a water change hoping to interrupt (what I thought was) a bacterial bloom.

That's why I was so aggressive with the water changes initially. Both to remove the bacteria, but also to have the mechanics of dumping water in the tank give it a surge of O2.

CoralJunkie had green water and even doing a larger than 50% water change didn’t help. By any chance is there aerosols/candles or incense being used around the tank?

Man what a pain. UGH.

I do light a candle couple hours sometimes. Maybe two or three times in as many months. Definitely no aerosols. I'm very careful with cleaning chemicals and such.
