Water level and light
 
I have a 20g tall with substrate planted Wisteria and a floating mass of Anachris and Red Leafed Ludwiga . It all has been growing fast enough that Iv'e been cutting half of it out once every 3-4 weeks. Then I started keeping the water level about 1.5-2'' below the top. ( I had been keeping it .5'' below the top.) I did my usual cutting and although the Anachris and Ludwiga bounced back as usual, the Wisteria has really struggled. Could the lower water level reduce light?

yeah, if plants are farther from the light, that could definitely have an effect on the growth. That's why stronger lights/higher wattage (correct me if i'm wrong someone!) are recommended for taller tanks, to reach down to the substrate plants.

It all depends on the plants Bekah. In this case I betting the lower water lvl is making it harder for the light to penetrate the water. Less of the light is making it to the bottom or to where the wisteria. The lower water is acting like a reflector lol its late and I have no clue as to what I am saying. But why not just raise the water back up and see if it makes a difference again.

The lower level is for Mystery Snails and a jumping Betta. I'm not sure how to fix this. Maybe let the Wisteria float?

The Wisteria is no farther from the light but the water is farther from the light. The Wisteria usually grows to the top and spreads, it's just having trouble getting to the top this time, even though it's closer to the top of the water.

good to know! that makes a lot of sense. this is why other people should always check my responses xD

do you not have a hood on your tank though?

Do you not have a hood on the tank? Or are you afraid of the Betta hitting the hood?

Yes, I have a hood but I need a lower water level so the snails can lay eggs out of the water.

No, the Betta is hard headed but the snails need a space out of the water to lay egg clutches.

Ohhh OK mine lay them right on the hood. Mine will climb the side of the tank and get on the hood somehow and lay them just fine. Even had them hatch this way. More then once in fact.

Back to the wisteria. It can be grown floating with no problem usually. I had some that I had floating once and it did great. Would put off some long white roots on mine like that.
