    Just wondering if anyone could identify what is going on with my staurogyne repens. Tank is a lower tech 40 breeder with 2217 filter, 2 36-inch t5ho Sunblasters and is stocked with Blyxa japonica, Hygro compact and the staurogyne. The tank has been flooded for two months now and everything else seems to be doing well. Here's what I've been adding to the tank:


    1/4 tsp kno3


    1/8 kh2po4


    1/16 csm+b


    1/2 tsp equilibrium


    This is added weekly


    1 capful of flourish excel daily (2 at water changes)


    Any help would be greatly appreciated!


    Thanks

    Thanks Solcielo!


    So add more kno3?


    Should I does more frequently?


    This is


    My first lower tech set-up so I'm struggling to find a proper regimen.


    Thanks

    New leaves are tiny - may be N and K deficiency caused by too much light. You can only have one thing limiting at any given time, but I suspect you're running low on many things starting with CO2. If you want a true low-tech tank, you may want to back off on the light.

    That's a lot of light for a non-CO2 tank. I'd double the potassium.

    The lights are suspended prolly six inches above the tank and I can adjust them higher pretty easy. Haven't had any algae issues just the problem with the repens. I'll try doubling the potassium and see if there's any improvements.


    Should I raise the light even higher than 6 inches above?

    I would. Get PAR to 50 or under at substrate.

    Unfortunately I have no par meter...I'll raise them up a few more inches.

    Do you see any snails around them? My staurogyne repens was doing great with my low light+ferts on my 6 gal nano until my snail population exploded and they got a taste of the delicious little leaves. I try to pick them out of the tank whenever I can but alot of damage has been done already. The damage looks similar (if not worse) than your picture above.

    There are snails in my tank for sure. All over in fact and yes they do get on the staurogyne. There is no possible way I could eradicate the snails at this point. To many snails and too many plants. I wasn't aware that the snails would do damage since they never did in my other tanks.


    Any suggestions to help curb the snail problem?

    I was wondering the same thing... I've just been picking them out/crushing the tiny ones with my pinsettes whenever I see them. Assasin snails are supposed to be good, but I got one and it has disappeared already. Other fish, like Loaches, are also supposed to be good at keeping their counts low. My 6 gallon nano is rather limited though in what kind of fish-only solutions I can use to eliminate these pests.
