Light chart translation?

I'm having a little trouble figuring out where I stand :)

I've got an 18" T5 15W 4,200K SunGlo bulb (just the one) over a 28 gallon tank, approx 18X24X~12

I think this puts me in the low light category, but I can't seem to figure it out. I can grow algae and Anachris like it's going out of style, but cabomba and hornwort have just turned brown and fallen apart in my tank. Java fern is a whole other thing, it's just snail salad right now.


I can't seem to find an 18" bulb with a higher wattage, so I suspect I will have to upgrade to a different fixture. Any suggestions?

cheers,

Ash

THATS WHATS HAPPENING TO MY JAVA FERN!?!? Arggggg stupid snails, I don't even know how they got in there :(

Unfortunately I can't help you out with the lighting, as I don't know much about it, I'm trying to figure it all out.

Thats interesting, because I had hornwort in my ten gallon with no light on it, and it did fine until I tried to "root" it with a rock and it just rotted and fell apart underwater. Hah, I don't think me and planted aquariums were ment to be.

I was trying to use it for a floating plant. It wouldn't float at all, just hung mid to bottom level, turned brown, all the needles fell off and it shot the ammonia levels in my tank off the scale.

The java fern is surviving. I have a gold colored mystery snail who loves to munch on it. I think I'm just going to move it to the back of the tank and keep it as a food source for him. Cargo (the snail) seems to leave everything else alone, so we'll see if the fern keeps him happy. The anachris is growing well, but the cabomba won't root and is going the way of the hornwort.

Maybe I'll just plant the whole freakin' tank with anachris. It's pretty enough.

Lol!! Funny, because my hornwort floated but I wanted it to sink (I actually thought it was supposed too ) , and your hornwort sunk even though you wanted it to float.

Really a mystery snail munching on live plants? Like Pomacea Canaliculata or Pomacea bridgesii?? They are easily mistaken, until the canaliculata grows to be about the size of your fist. But pomacea bridgesii, a true mystery snail, doesn't normally eat live plants? I mean obviously all snails are capable of eating live plants. But even in my planted aquarium my snail would only eat the occasional dead leaf! In fact the only time I saw him eat plants they were dead.

Maybe your guys a little hungry? What do you feed him?

I like the anachris, its really nice. It looks like good hiding spots for fishies too :D

Cargo is in charge of the clean up crew plus he gets algae wafers and the occasional shrimp pellet.

I know I can do veggies also, but I never get around to it. There's not a lot of produce around here. It's a very 'bachelor' set up :)

The SunLight bulb probably has the wrong spectrum to grow aquatic plants efficiently. Also it is of the wrong Kelvin rating. Look for a bulb in the 6500K range.

Got a new bulb, some new plants and some new fish :)

I got a 'life-glo' bulb this time. 6,700K.

I found a nice LFS (World of Pets, if any of you are in the Florence, KY area) and they helped me pick out some really beautiful plants. I have two Cryptocoryne wendtii, what I think is Brazilian pennywort, and something else that I can't remember the name of... looks like ludwigia only not so dark green and only a teeny bit red under the leaves?

I also got some API Leaf Zone fertilizer. So here we go! I'll report back in a week or two.

p.s. The new fish are 6 giant danios. I got all the plants at WoP, but I did have to hit Petsmart for the lightbulb, ferts and fish. They just didn't have exactly what I wanted in stock at WoP and I'm an instant gratification kind of girl :)

Ok, so google=good

The new plants are indeed the two previously identified crypts, brazilian pennywort (staying in the ten gallon, anticipating a betta tank) and some variety of Hygrophila corymbosa. I did my water changes today and added in the new plants. I'll have pictures up later, after the dust settles, so to speak.

I also added in the new light bulb, it is in the current fixture for this tank. I dug through my closet and found the extra light fixture that was 'thrown in' when I got my set of tanks from Mr. Ebay and put my other bulb in it and added it to the tank. The new bulb (life-glo) seemed to wash out the colors on some of the fish, likely due the 'pure white light' factor. With the addition of the 'sun-glo' bulb again, the colors seem richer.

I did a lot of pruning and replanting with the anachris and cabomba that was already in the tank. I now have two bunches of cabomba along the left side of my tank (hiding the heater), three bunches of anachris in the back right corner of the tank (hiding the filter), the hygro is off center in the back, and the two crypts are dotted across the front of the tank around the big 'tree trunk' decoration I have. I also anchored my java fern on that trunk today. So hopefully that plant will also be much happier soon.

I had my first go at fertilizer today. I dosed 15ml of API Leaf Zone after my water change. Here's hoping it all works out. I'll keep you all posted on the progress. I'll have another thread up in a few days with some pictures.

Cheers,

Ashkat
