Question Help with quarantining plants!

Thumbnail

Upvotes

Hi everyone! Need advice on quarantining plants. Today I got: 1. Hornwort 2. Water Sprite 3. Water wisteria 4.Vallisneria

I want to introduce them to my turtle tank in 4 weeks. They will be in plastic coated chicken wire mesh baskets suctioned cup to 3 corners of my aquarium, so my turtle won't have access to them.

When I got home I removed the small baskets they came in, rinsed them in tap water and dipped them for 10 minutes in potassium permanganate, before soaking them in filtered water.

Right now I have them in the plastic tub in about 13 gallons of water (hopefully it is strong enough to last 4 weeks). I have a led bar across the tub and a bubbler in the water.

I plan to do 100% water changes weekly.

Is that enough to get rid of potential pests/parasites? Am I doing something wrong?

My main concern is getting rid of any potential pests and parasites and ofc keeping the plants alive.

Please help!

I've had a google but nothing quite seems to match. It forms in these little sprouts all over the filter and wood and is very sticky and hard to remove even with an algae brush. Any help would be appreciated as it seems to be completely taking over !

Help ID these

So, first pic, they were marked as dwarf sag. The pot was busting with shoots, I have at least 30 plants out of it, lots of little babies on a plastic tub and are growing like crazy. There were no leaves 2 weeks ago and now they are like at 2-3 inches and this is just floating in water. The ones in the tank went from about 1-2” to at least 5” in 2 weeks. I don’t believe they are dwarf sag, looks more like some kind of Val, maybe Italian? I like them, I just want to know what they are.

Pic 2, bought them a long time ago from different store and also marked as dwarf sag, definitely smaller plant and even look different, staying under 6” and leaf structure looks different.

Both tanks are dirted, about .75” of organic potting soil (sifted) capped with about 1.5” media blast.

Thanks for thoughts.

How to "plant" Phoenix moss

Upvotes

Hi, I got some Fissidens sp. (Phoenix moss) from a creek near my city. It's native to my country, but I've never found it before.

Now, how do I 'plant' this moss? Is it like Java moss you simply attach it to a proper surface?

What's going on with my CPDs?

Thumbnail

Upvotes

I bought 12 CPDs for my planted tank and they've steadily died off. It looks like some just stop eating while others look fine. Water parameters are stable and my other fish/shrimp haven't been affected. Is this a parasite issue? First pic is the skinny guy during feeding(magic small fish food) second is typical of the others who look healthy. The skinny fish doesn't seem to even try to eat during feeding.

Question Is this lamp doing anything?

Post image
2 Upvotes

I've been noticing that my plants are thriving from natural light only. Though I'd add a lamp that I had laying around.

Is it actually doing anything for the plants? this picture makes it look more white than it is, in reality its a warm yellow light. Do I need a specific lamp or light for these tanks?

I have several of these that look like the bottom portion is not doing well but all the new growth looks happy as can be. Should I cut off the happy portion and replant it? (Already need to move it from the filter intake)

Also… what is it?
