Ochtodes Macroalgae turned brown

For the blue Ochtodes macroalgae, it is normal that it will turn brown, once taken out of the water and or in transit. But once back in the marine water and with the right light it will turn blue/violet again normally within a few days.

Ochtodes Macro Algae turned red / orange

When your Ochtodes turned red /orange or white it is, unfortunately, a sign that it got too much stress and that it is dying off. Often this is a sign that the water parameters are not good for it or it was too long in transit. Please remove the parts of the algae which changed to those colours from your tank, as it won't, unfortunately, recover from this. Parts which still look brown/purple/blue are good and will grow on with the fitting water and light conditions.

Hi Jack. Thank you for your message. When a starter pack is bought together with other macroalgae we will always try to add other macroalgae species for you and we normally pack them as they come.
When you buy two packs it might be that you get some similar algae species.

I would recommend adding macroalgae when the tank is established and you have the fishes already in for a while.
As with them your tank normally will have enough nitrate and phosphate the macroalgae will need to grow. The other nutrients macroalgae will need to grow you normally will have enough when you do normal water changes.
In other words no need for any fertilizer :) Just in a macroalgae only tank, or where nitrate is below 2ppm / or phosphate below 0.02 it will beneficial to use a fertilizer or a special supplement to replace the used nutrients.

Hi. Thank you for your question. We know that there are different opinions about what grow light spectrum is better for macroalgae to grow.
When it comes to Chaeto we recommend to use the bloom setting with the Kessil H380 as it offers a bit more intense red light & a bit less blue light than the grow setting which is for Chaetomorpha a better choice from our experience.

Both settings will produce though a good macroalgae growth. The grow setting we recommend more for red algae species, like Gracilaria for example.

We hope this helps and when you have any further questions please let us know.
