my homemade ATS acrylic box

[dota]

hi, how do to stick the 2 screen together..?
i would like to try with a glue, but i just worry it will harm the fish /coral ...

[SantaMonica]

tie wraps, or fishing line

[dota]

oo.. thats right.. :P
Thank you

[dota]

however, which one have a better filtering..? the double layer right..? or it just about the same..?

(im using single layer at the moment )
i'd like to try the double layer, coz when clean off the screen there are still some algae left in between the screen..

[SantaMonica]

Double is better if you have strong flow (50 gph) and strong light (1.0 watts per gallon), and if you clean often. Otherwise, the thick screen gets thicker too quick and blocks too much light.

this is the 2nd week of scrubbing. it's been 2 weeks but my green algae seems so little.. most of it Red and brown ... there are also some dark green algae..
Well, my nitrate is about 50mg/L, is it the cause?

[SantaMonica]

Yes. More light power, or more time.

i got 14W x 4 TL bulb.. (each side)should take 1 off..?

[SantaMonica]

Use them for now.

ive been running my ATS for more than 1 month... but the result... nothing untill now.. nitrate still very high 50mg /l, i dunno bout PO4. i dunno wats wrong to the water...

well, i didnt really clean the screen every 7 days..
ATS is my only filteration system.. im not even using the sponge filter anymore.

i thought in 1 month my nitrate will be down to at least 10 - 15 mg/ l...but not even close..

Im hopeless now
