Holiday what to do

[nellups]

its that time of the year again, hols! need one as well! BUT i have some concerns about my 75L topless tank its being running now for around 3 months has 2 clown fish, 1 bi-colour Blenny and a soon to go yellow tail damsel, CUC - cleaner and sexy shrimps, pom pom crab porcilien crab and snails, along with some corals.

 

Problems - expected heat wave July and August! we are going the second week in July, when the heat got high two weeks ago my tank hit 29° cooled it down with fans - 2nd problems evaporation every day around 1 litre - 3rd problem skimmer needs emptying every day - so what do I do? have a friend who will pop in to top up and check the salt levels - fine i hope, - should i leave a fan on all the time?

 

and lastly the skimmer is there a way of drilling a hole in the plastic and connecting a hose of some sort so when it get to a certain level it overflows in to this and down into a container? how to connect the overflow pipe to the plastic cup?

 

Besides all of this is there anything else anyone can think of? I am really worried about leaving it its my first try at marines always had Discus and never worried about them - and they so far have never had a problem.

 

Any help or ideas greatly received

I'd disconnect the skimmer while gone. Have a distinct fill line for top offs (or implement an ATO unit). Pre-measure dry food for feeding (Dixie cups work fine here).
