水草情迷

有冇人知uv燈係應該長開定係有需要先至開?
因為有人話長開會影響水入面既養份組合,簡接影響水草的生長,
有冇高人可以指點迷津?

我就會長開
因為uv管每次開關都會縮短壽命

UV 會光解某些藥品, 不過肥料就未聽過會有事.

Not sure if it's absolutely true but UV light can destroy micro nutrients like Iron, making them useless to the plants.

Also,

I read that when people have their UV on all the time, they dose high amount of micro nutrients everyday to keep up with the loss (they often use diy trace mix so cost of fertilizer is not a problem )

I have a UV on my tank and I am also using diy trace mix. But I didn't turn it on all the time simply because there is no need of it in a balanced tank (hopefully it is... ). Well if you really want to use UV but worrying about the fertilizer, you might consider doing the following: turn on the UV after weekly scraping of glass and water change, turn it off the following day, then dose back some micro nutrients. With the UV running for a day weekly, your tank could get a bit more advantage over the algae (planning to do that eventually...since I got the UV anyway)

p.s. BTW I am not a "tall person" (expert)...just thought that I should share the ideas...

其實好大機會真係UV light攪到水草吸收唔到鐵,
因為我d矮珍珠有少部份已經呈現白化,就係我放左uv燈之後發生的,睇下加d ECA會唔會好d先!
