問題似乎解決了!
用 2215 推25-36W uv 是可行的. 但高差最好不多過 1.5米!
用 2260 推水冷也沒問題!
至於燈的問題, 我都認為 Arcarti 是不錯的選擇, 如無貨的話我個人會考慮從二手市場購買 good condition 的 Series 3, 又或者買枝大陸燈例如 Atman 然後揾人改晒用 Philips 電子牛和較優質的接線, 效果也會不錯的!
big brother, u are finally back.

i was waiting for u years.

haha, coz you can tell the theory and your experience to tell us what to do. it is more easy to understand and got an excuse to trust your theory.

i will use the 2215 as a pre-filter for the 2260. I have purchased a 2217 today, which i can push it for the uv & as a second filter to join the n-cycle in a big tank.

I have put the 2217 onto my 18" tank now.

the bubbles of the plant is like triple from before. maybe the flow rate of 2215 is not enough even for my 18" tank.

it is easy to get cheat by others since i don't know anything in the electronic. i know the glo is good enough for me but i like to have an open top, so the maintance is more easy and looks much nicer. so, i try to move to something with open top. so, i choose arcadia. but, the hk dealer didn't have anything for 48". So, i have to give up again. i went to see the ada solar. but, it seems to be too small for a 20" depth of tank. then, i look at the ada grand solar. bingo! but quite expensive.
so, what i will do now is i see if i can purcahse the arcadia 48" later(either t5ho or hqi depends on the price). otherwise, maybe grand solar 1. what i found is that the ada green bulb really looks smooth and the light wouldn't shoot onto your eyes so much. what i will do is i will try to get arcadia 48". if still not available when i make my purchase, then i will go for ada grand solar 1 mostly.

you only have to pay the equipement once, so it is alright even it is so damn expensive.
ada grand solar : $5500- $1000 for the hqi bulb - few hundred for the tube. then you will feel a little better.. haha. this is a stupid solution.
