How are your plants adjusting to being submerged?

I was considering it but didn't have the time. My landscaper (he's an expert in tropical terrestrials and travels in search of rare plants). He showed me the exact same plant (Sonchus variety) growing next to my roses but with a deep green and no pink coloration. He reminded me that the lighting I have in my refugium was responsible for the color difference. Here's a look at the plant I pulled and the terrestrial cozying up to my roses.

So far so good! I've kept the waterline at 2 inches as the refugium may have to be moved when plumbing starts - hopefully no later than next week.

The Bacopa seem to be getting a boost as they're poking their heads up more than when they were in the DSM stage. I assume the water is helping them to do so.

The HC doesn't show any negative affects and I'm crossing my fingers it stays that way.

Great! It sounds your tank had a smooth transition. In a way, you have created a wetland environment, which is highly favorable for robust plant growth.

“Wetland” was my first thought when I stepped back and took it all in. I'll miss this stage which confirms that one day I must have a paludarium!

One of the possible issues with DSM is that my Bacopa monnieri had the opportunity to put down roots as it progressed along the substrate. I know this is a good sign but it has gobbled up a lot of real estate.

I don’t know if I should add new plants between the tight spaces and let the plants work it out or wait till I flood the sump and pull some of the stem tips up so they’ll be vertical and free up substrate.

My only concern with the second option is many stems have gotten long and pulling them up will expose numerous roots. I don’t know if this will stress the plant or if the roots will be fine in the water column.

Any advice is welcome!

Well, excessive plant growth should not be a problem in a refugium!

If you decide to add other plants, I would trim a little here and there to make room for the new plants. You can always shave the roots off of some stems to let the Bacopa stand more upright in the water.

A razor blade or nail scissors might help with a "surgical trim."

Thanks, D! That's a relief. It'll be easier to have some vertical.

While everything seems to be OK in the current wetland state, I'm a bit concerned about HC. For the most part it's fine but I am noticing yellowing of some leaves. Consequently, I've been toying with the idea of adding a small amount of Flourish Excel in my spray bottle and concentrating the spray only around the HC.

Does this sound like a reasonable approach? This is about the only time I can do this before I start introducing more water which would make directed application difficult.

If the HC still has leaves in the air, it gets all the CO2 it needs from the atmosphere. (See the Emersed Advantage in Diana's book.) Excel is used as a carbon source only for plants that are completely submerged. IMO, it is completely unneeded in a Walstad tank.

[QUOTE=ChrisKane;911609I'm a bit concerned about HC.[/QUOTE]

I am confused (which is not hard to do). I thought the refugium's purpose is to absorb nutrients from the main tank. If so, why have a low-growing plant? Wouldn't it be be better to stock it with fast growing, nitrogen sucking plants?

And congtrat's on your thread going two pages.
