So I recently replaced all 8 bulbs on my t5 ho lighting system on my 46 and added purple up. I have had problems with cyano but I do 25% every week, my bio load is minuscule, and I have cheato even growing the tank itself! My water tests perfect every time and my corals are doing great. Sadly my coralline has died off so I've been looking for some options. I was told that the spectrum must have been off with my bulbs which has sparked the cyano growth which has acted as competition for the coralline.

I'll keep you guys updated on my results but just wondering if there's anyone out there with similar issues and if u have had luck with my coraline recovery strategy.

Thanks

Cyano doent use same nutrients as corraline coralline uses calcium and alk cyano is phosphates id say the bulbs will solve the issue provided alk cal and mag are good

If there is no nutrient then it must be the lights.. But only time will tell. Anyone had luck with the purple up though?

It is your calcium and alk levels. I grow coralline algae in dark areas and under rocks, so I doubt the light had much to do with it. Purple up is mostly a calcium booster.

I've used it before. It made the tank cloudy when you dose it. It didn't raise my calcium as much so I switched to kalkwaser. Coraline algae will start to flourish in your tank eventually once the condition is right. At first it takes a while to get it going but once the growth starts it'll cover your tank fast. You'll even have to scrape them off the glass every couple of weeks or so

Kalkwasser is the cheapest and most efficient way to go. You can maintain calcium levels with two part solutions and purple up, but it takes Kalkwasser to raise them to the right levels. Also a good salt mix will help as some of them have high calcium levels when mixed. Kalkwasser is cheap.

Sounds great thanks but as for the weird cyano stuff... It not like any slime that I've encountered in the past. It's sort of light brown and hairy and basically shows in the form of bubbles coving everything from sand to rocks, I've tried the slime remover medication but the stuff went unaffected.

Any ideas?

Sounds like diatoms. Selenium can have an effect here. Selenium comes from city water and some types of sand will also contain quantities of it. Diatoms come and go, so they might disappear on their own. Siphoning it out is always a good idea.

If you look closely at the rock you will see the weird bubbles I was talking about. Periodically the release bring bits of the sandbed with to the surface.
