i feel that acrifix will be good if u are thinking of glueing acrylic with pvc but as for acrylic to acrylic, chloroform is still the best....but the correct preesure applied when joining and the room temperature as very important elements....
dun ask me specifically wat room temperature or preesure, i also dunno....
i did ask an expert in acrylic b4, he said he used purely chloroform but did not tell me how to use it properly...if done accurately, the join will not split, the whole acrylic will break instead....
i am also trying to DIY a skimmer, also in the same dilemma as creetin.....maybe we can discuss through PMs???
