Help needed


Hi Folks

I recently set up a new Fluval Roma 125. Its been running for a month now and all has been well until recently. Its a double island type set up with both islands raised and the substrate is fluorite black. with aquarium sand along the front and in between the islands. I have red moor roots with Anubias nana and Bonsai, java fern and Java moss attached. These are all growing well.
Planted in the fluorite I have Bacopa Caroliniana, Staurogyne Repens, Echinodorus and straight Vallis. I have been using Seachem flourish once a week. The Bacopa and Repens wee growing fine, with some Bacopa reaching the surface.
My problem is the Bacopa leaves now seem to be melting and the Repens is slowly starting to turn yellow.
The lighting is standard for the tank two 15 watt t8 tubes. One aqua glow, one power glow. I was told to only have the lights on for 6 hours for the first month as it is a new set up. Should I step it up to 8 or 10? I am not using co2.
What could be causing the demise of the Bacopa and Repens?

You do not have complete ferts. It may no be the complete answer either, but won't
hurt to remove that as the cause by starting them.
Do not just run out and buy the first thing that comes to your mind. After reading the link, ask more questions on here as there are many options.

Welcome to the forums!

Any chance of some pictures?

Are the newer or older leaves turning yellow? Does it start from the inside or outside of a leaf? Are there any holes in the leaves?

Thanks for replying guys, I'll try to get some pics up soon. The leaves don't have holes in them there going yellow from the tips of the leaves inwards, the very top few leaves are ok it seems to start about 3 leaves down.

The plan was a low maintenance set up so I don't really want to go down the co2 route.

Sounds exactly like a nitrogen deficiency, but we need to see photos of the plants first in order to be sure.

Which "Flourish" are you using? I know Seachem's labelling on the bottles is really misleading, but "Flourish" is actually the name they use for their entire line of fertilizers. There's Flourish Excel, Flourish Comprehensive, Iron, Nitrogen, Potassium, Phosphorus, etc etc etc. You actually need to buy quite a few different "Flourish" bottles in order to provide a balanced fert regimen for plants.

lauraleellbp is right, "Flourish" is quite misleading. Many people generalize by writing "Flourish" but it is pretty non-descriptive.

Most of us use dry fertilizers which provide several years (sometimes decades) worth of fertilizing for our tanks instead of spending the same money on liquid fertilizers that last a few weeks.

Many people buy from this site (and other sites):
http://www.aquariumfertilizer.com/in...ditU=1&Regit=2

KNO3, KH2PO4, and CSM+B are the bare minimum you want to buy though it is nice to have K2SO4, and DTPA chelated iron.

Lovely aquascape!

Looks like you need to put together a better fertilization regimen.

Stem plants grow the most quickly, and therefore their demand for nutrients is much higher than the rest of the plants you have in there.

Old growth is yellow. Probable nitrogen problems. Add KNO3.

Also, there may not be enough light in there for the repens.

Thanks, its not a good picture, I'll put a better one up later.

What should I be feeding them, is there anything that comes close to being the complete fertilizer?

Will any ferts damage my fish?
8 cherry barbs
2 German blue rams
1 Gardneri killifish
4 Corydoras Julii
2 otocinclus

The Flourish I have been using simply says Flourish "comprehensive supplement for the planted aquarium".

Flourish Comprehensive's label unfortunately is quite misleading. Comprehensive is mostly just micro and trace nutrients- actually, those nutrients that plants need in LEAST amounts, compared to carbon, nitrogen, phosphorus, and potassium.

If you want to stick with Seachem's line of ferts, you will need to pick up quite a few more bottles. Their "Enhancer pack" is the macro nutrients that plants need in the greatest amounts. Seachem has a recommended dosing chart on their website.

No, ferts will not hurt your fish.

Most people/w some experience use dry ferts or mix the dry ferts into a solution and dose that. Actually there is a step by step thread up here right now about what is called EI ferts. Simply put, you add more of each kind than necessary for your sized tank and dilute it each week/w a water change so it don't build up on you.
http://www.plantedtank.net/forums/sh...d.php?t=621810
Look through this and get back with the next question as I know it will only cause more of them.
This is a list of some of the places you can get these ferts from. But learn a little before buying. Just remember you have this list on your question.
http://www.plantedtank.net/forums/sh...393&highlight=
http://greenleafaquariums.com/aquarium-fertilizer.html
http://aquariumfertilizer.com/index....ditU=1&Regit=2
Two of them have "kits" which supply you/w the bottles to make a liquid solution of the dry ferts with to simplify things.
You still need to pick a type to use and find out how to tell how much you need for your tank size.
