Changing the 75g and the 125 g to sand, might be fun esp with fish in, Will take pics and post later...going to make a mess now!

Sweet! Should look good when your done. I can"t wait to see it!

Best of luck with conversion MC!

How hard is it to change over from gravel to sand?

Not too bad but getting the sand clean is a PITA. and removing gravel and adding sand with fish in is a bit tuff....just finished the 75g still cloudy as hell...I doubt I will get to the 125 tonight but maybe.

Yikes! Doesn't sound like fun. Can you get all the fish into buckets, drain and then make the substrate swap?

wow that does sound like a pain i hate switching gravel without fish in there lol

Good luck with your conversion, Paul!

Good luck man. I did this a few months ago. Went from crushed coral to Crushed granite. Not to bad of a time but I washed the shiz out of the new stuff.

Well not going so good....rinsed the hell out of it and it is still dirty as hell....Who ever suggested play sand should be shot. I am almost going to take it out and start over.....two days the tank is still clowdy 5 50% water changes...I am pissed off right now. gonna do a 100% water change when I am done with the rest of the tanks water change today. If that dont help going a different route.

I went to a local hardware store when I was thinking about using play sand. I took a look at it and it looked very dirty and silty so I decided not to use it. I have heard pool filter sand is a much better option but haven't tried it yet.

Playsand.... SUCKS!

Pool filter sand is much better. Much more uniform granules and less dust.

I want to do my 180 to sand but unsure of what sand i want to use. I think i will do some serious research now. Hope things work out for you MC on the cloudiness.

Really sorry to hear that MC. I used play sand for my 30 gallon but not while the fish were still in the tank. I think you will get much better results with the 100% water change.
