I have one of those gravel vac cleaners but i have very fine crushed coral at the bottom so when i try to clean it, it picks up all the coral too? I dont think they make one for coral do they?
you can change substrate as long as you do it carefully. it can mean taking everything out the tank (i've heard of people not doing that, but i would, especially with sand). get a PH reading of your tank first to see if it's necessary.
Ok i will get that one then if its better than strips! Will be handy in future as you said. What happens if my water is wrong then? Do you buy stuff to level it all out? Does it tell you what to do in the test kit if its wrong?
