Finnex Planted + Vs Finnex Stingray

[Stella]

I’m looking to grow low to medium light plants but have no desire to use co2. I do use fertilizer though. Which light would you suggest?

I use the Finnex 24/7 on both my 60 gallon tanks and have been really happy with it. Cannot answer questions about the Stingray though.

I’d be using the light on a 10 gallon and a 40g, if that makes a difference. Gundy1024, you’re tank looks really nice! Do you use co2?

I do not, I dose Flourish, Iron and metrocide14 weekly.

I’ve got the flourish. What’s the Iron and Metrocide14 for?

 

[Gundy1024]

Plants use iron to produce chlorophyll, so a lack of iron results in a lack of chlorophyll, and thus yellowing of the younger leaves. So basically it will make you plant greener and healthy. Flourish excel is a CO2 substitute. Plants use CO2 for photosynthesis, low CO2 will slow down your plant growth. I did not want to invest in a CO2 system so I started using Excel since it is a liquid CO2 substitute. I later started using Metricide14. It is the same base component (glutaraldehyde) as excel but has to be diluted to be safe for you aquarium. I would not start using that until you have researched and learned all you need to know about it.

Hmm, the iron might explain why my plants are still growing but turning yellow. Since you know more about this than I do, could the light be connected to plants growing but turning a yellow/reddish brown?

 

[Gundy1024]

That I do not know. I know that once I started using the Finnex 24/7 and letting the plants get about 8 hours of max power they have done great.
