Is your life too busy right now, too much other things going on to give the tank a bit extra effort???
A regular SW
tank should be enjoyable for you not just the biggest pain ever! So just think if you WANT to do the moderate extra effort and if that effort gives the the higher level of happiness to warrant the work.
Of course you can do it. Sometimes a change of materials or strategy, method can make the change to get a better result.
It sounds like the algae from hell was a big trial. Can you do something to ensure the algae is finally dead? Does H2O2 work for these rocks like with FW
? You can't boil... toxic possibilities.
Sorry to hear of the heater issue and your losses. Recently I had a heater stick and over heated the tank too before I found the issue.
