水草情迷

Hi all,

My tank is 32 inch about 140 Litre net using a 204 Fluval MSF, I think this may a bit under but just so far so good because I do not have a lot of fish.

Recently I brought some tenellus for foreground of my new setup. Firstly I think all should be well because of using black mud as substrat which produces soft water and low pH.

After some time, they seems grow not well and very slow......firstly I think there is a problem on lighting/fertilizer so I put some effort on those such as increasing bulbs (1 more LifeGro) and add step 1 /brighty K fertilizer (previous not much). But the result is still NOT OK.

Today, I stopped the filter to trim some died plant leaves. After some time, many tenellus giving bubbles continuously .

I was so superising that they are taking photosynthesis so actively under still water (no flow).......what should I do?? Stop the filter to let them to take photosynthesis?? As I ready don't think the flow rate is fast actually.......I then turn it back on and the tenellus were stop producing bubbles......

Please help me.....as my tank No3 reaching 40ppm whatever doing 1/3 water change weekly....I need them use no3....

並非你停了filter才有光合作用,
其實你的草一直都有行光合作用,
只不過平時有水流, 植物光合作用產生的氣體很快被帶走,
所以較難產生氣泡,
而你停了filter後氣體較易積聚所以你可以看見氣泡.
記著並不是有泡泡才代表植物有行光合作用,
有泡泡只是代表你缸內的氧氣達飽和程度~~
希望幫到你~~

終於明白我的水草最近無氣泡的原因, 是加o左水桶濾水器之後.
