I realise this is an old post but was wondering how the two RSM 250 Media Rack fuges are coming along or have they been ditched.
I saw Danreef had his chaeto stop growing & he had to restart (in his tank thread)...
Would you do it again guys?
Would you encourage others to start a fuge in the media rack?
My Chaeto stop growing but that wasn't related to the in tank fuge design.
I stop my fuge in the RSM because the 3 submersible lights sold by In Tank, and many other sellers, at the end FAILED. I had water entering in them. Replaced the bulbs and again water entered. I was not able to find a suitable light that I can place in each rack level. Or a LED strip that can be used to provide light to the 3 levels.
So I have to take out the remaining Chaeto.
I have built now an external fuge for my RSM 250, because I was lucky to have an adjacent room to my tank that is my small tool / fish staff room.
I will attach some pictures later.
Bottom line: if you figured the way to provide light to the 3 levels of the In Tank medis rack OR if you do not use the In Tank Media rack and just place the Chaeto in that section and place a sumergible LED strip that will NOT fail with time under water OR provide light in the classical way (from the top), I do not see why it will not work.
There are many guys, with the In Tank Media rack, just using the upper level with Chaeto and the 2 lower levels with Chemipure and purigen, as an example.
Mine worked in the meantime there was food for the algae and the lights worked.
