What's up with the Vals'


What's up with the Vals. Are they high light or low
light plants? Do they like Co2? They grow hardy and
then die off. What's the trick? Some of these planted
tanks I see, the Vals look like they are out of control.
Do they like ferts. If so what kind?

Only smarts ones need to reply!

they are fine in high light or low light, CO2 or no CO2. They are sensitive to Excel (it causes them to melt in high doses). Otherwise I have found them to be very hardy and quite invasive. I normally dosed EI.

Hope that helps If you say what kind of setup you have maybe we can help more.

Jungle vals are also quite aggressive, but they are fantastic for low tech tanks. They are absolutley a plant and forget it solution. No ferts seem to be required!

My corkscrew vals took several months to finally start growing. Now they are taking over half of the tank, and I had to do some replanting last week to keep the area in the front of the tank open. No ferts or CO2 required. 55 wats over 29 gal tank is medium light at best. Still, vals grow very well.

29g eco, DIY up to 81W PC (55W used), Rena Filstar XP2 Filter
Corkscrew Vals, 2 angels, 4 corydoras aeneus, Ramshorn snails, MTS
5 gal RCS tank with sand bottom, java moss, small internal filter, MTS, Ramshorn snails.

Up with Val's tank params.

Hey again!

This is in reply to Oblongshrimp's inquiry!

I guess it would help if I gave my aquarium params.

60 gallon acrylic, fluval 404, spray bar, Co2, pressurized,
with reactor, Tom Barr design, Current USA Power Compact
fixtures with SunPac 2 dual daylight design, which is 4 67000k/
10000k white, 4 65w lights. Too much, Huagh!
Tap water 7.8, very high in phosphates, use half filtered water
from LFS, and half tap, to replace half of tank once a week.
Drop checker showing green at all times with about 2.5 bubbles
p.sec. Lights are on 8hrs. with 1hr. break. Ph. 7.6, Nitrites 0,
Ammonia 0, Kh 7, Gh unmeasurable. Can't get the ph down
to 6.8 or 7.0 with Co2 at night reading. Discus fish 3 wilds,
2 domestic. EI dosing. Right now I have staghorn algae
and brown algae throughout. Swords, ludwigia, crypts- wendti,
red, hairgrass, wisteria, anubias nana, bacopa caroliniana, lloydiella
and vals. So I am back to the Vals. I figure if the Vals aren't
growing, then the rest are going to falter also. I live in metro area
of LA, suburban water with high phosphates. I am thinking about a
RO unit. I guess I might have to much light, and causing the algae.
I am thinking about going back to my 2 65 watts set up and see
if Co2, and EI dosing create more of a balance.

Any thoughts for corrections is appreciated!

i also think vals are pretty hardy to water conditions,light etc. there like an amazon to me easy and hard to kill in any tank.

i think its a b#[email protected] to find your "right" spot for lighing co and ferts. you can use your current lighting but maybe cut the hours back as it seems the c02 is good. id try 3 on , 2-3 off and 3 on again. or just try the 2l ights for 8hrs i remember putting a sheet over the tank for 3-4 days to get rid of the algae problem that always came back lmao. my personal experience now is to much light= algae, c02 or not.

I have a friend who used plastic landscape border trimmed to size from tank wall to tank wall to "corral" his Vals into the area he wanted them to remain- said it worked pretty well. Another option would be to plant them in small plastic pots and trim the tops down to just over the substrate depth (if you're the least bit too low the runners will "escape" though LOL)
