Zetlight E200S

mx36 · Jan 17, 2019

Anyone use the Zetlight E200S on their refugium? What are your thoughts on it? Can not seem to find any reviews on that model. I only Have about 12" from the top of the water surface to the top of the stand so I am needing something like this as I think the kessils lights would be to close to the water surface. The depth of the water is only about 10".

I have not, but lets see if some else is on today that can help

I have one. Refugeum is half of a 55g tank... 24" x 12" x 18".

It's got it's own controller in it, connect via wifi, intensity, color, ramping, etc. It's a bit odd in how it's configured, but once you figure out what they're doing, it seems to work OK. Remembers it's settings after a power outage.

Form is pretty compact. Quality of construction is very good. Rubber sealed, etc. Easy to wipe down the face when it needs it. Included flex mount works fine.

I've got C. Mexicana and Chaetomorpha growing under this light. Both grow well.

I've got a bit of an issue with bubble algae in my display tank. I'm currently trying to cut duration and intensity of tank lighting in order to rid myself of it. So far, so good. It's taking a while, but I've seen a substantial reduction in bubble algae.

Greybeard...would you mind sharing the settings for each of the 4 channels that you are using, successfully?

A=42%
B=100%
C=100%
D=100%

I'm ramping up to those values, and ramping down in the morning... Total duration 12 hours on.

C. Mexicana, which I've tried to eradicate from my refugeum several times... keeps coming back

Chatomorpha grows well.

IMHO, if you can't grow macro algae, it's unlikely to be a lighting problem. This stuff will grow under just about any light. I used to grow macro algae under cheap grow bulbs... got friends that still do. Low nutrient levels are a much more likely cause for failing to grow macro algae.
