no worries bro, appreciate your help very much
:)

very good and detail guide... I should have see this thread before I do my 422..

the measuring part was a headache and at the end, the base aryclic were cutting by 1cm smaller.. so when put on the base it will shift due to the wave inside.. at the end I have to use another pic of small acrylic as stopper to push both pc together tight to prevent it from shifting..

but no worry, I will try your method again when I do my 522 next time..

thanks

Thks for ur feedback bro .... I assume urs is no bracing below ? And wat u mean by wave ? like wrap ? How thick acrylic u use ?

Actually i find measuring tank without EOS and bracing easier but putting it in will not be as nice and fitting compare to those with full euro bracing .

With bracing the acrylic just fit in nicely . :)

Now you very pro liao, in this change base acrylic service. Thanks for the sharing here!

Haha bro...lazy travel all the way down and my old acrylic becomes useless le :p..

Peeboopee i dunno wat u drawing ... both look same to me !!! :D

Can u measure ur bracing first see if top and bottom is 3 "
See how i measure ... the top one may look like 2.5" but cause of camera angle . U need to stand high ontop ur tank to see .

Then tomorrow i teach u how to measure using my method against my drawing .

diff lah.. one the acrylic touch the underflow.. another one got some gap.

i think mine tank is different.. my bottom bracing is at most 2inch... i measured internally.. and my bottom bracing doesnt go all the way to the underflow.. as shown in the drawings..

i went kwangyi was quoted $81 for the 2 piece acrylic.. but i didnt bite becasue no matt white.. only got 2 white.. 1 glossy opaque and 1 translucent..and have to wait 1 hour... so think go ubi better.

I went ubi also no matt white for 5mm thickness which i want. Matt white only available in 3mm. I got glossy white cause buay lun. Turned out good. I felt the texture on the matt white. Its grainy. May have problems scrubbing off algae in future.

This is the matt white at dama.
