[img]How to change out your substrate without re-moving fish:



1.First rinse the new substrate and have it in a Rubbermaid and ready to go. You do this by filling a 5 gallon bucket a little less than half way with material and stick the water hose in there with it running. Stir it around, using the end of the hose, till all the dust particles and garbage floats out and the water runs clear. I tilt the bucket a little and let it pour out in the yard. If you use one of those brass shut off valves you can turn the water on and off as needed to dump and refill the bucket, then it won’t waste water.

2.Drain water down enough to get your arm in there and remove the rocks. Leave as much water in the tank as possible. You may want to turn the filters off. Depends on what type of substrate you are removing. If it’s gravel leave them on. If you’re removing sand turn them off.

3.Take a plastic dustpan and a Rubbermaid container and remove the old substrate into the Rubbermaid. You may want to take a break and turn the filters on and go clean your rocks at this point.

4.After rinsing the new substrate take a large plastic butter dish or bowl and start scooping the new stuff in there. You want to set the bowl full of clean sand all the way to the bottom and release it slowly so there are no dust storms.

5.After all the new substrate is added, drain the tank as so to do a 50-70% water change. replace rocks. Refill tank.

6.DO NOT clean filters for at least 2-3 days. This should only be done only on a well-cycled tank. You will be removing the bacteria in the old substrate and a lot of the bacteria that reside in the water. The bacterium in the filters is all your fish will have to survive on.

Cleaning sand substrate-

If you use sand,watch out when cleaning the glass,it will scratch it.I use a Kent stainless scraper down close to the bottom and a scrub pad up higher.

Run the intakes on the hang on filters without extentions.If they are high enough the fish won't spit sand in them.Sand will shred a hang on and it will make noise from then on.

The idea when cleaning is to vacuum the poop off the top and stir it up a little.If you get it plugged up in your siphon hose you have just messed up!Some recommend a nylon stocking for catching the sand then dumping it back in the tank.Or run the end of the hose in a container.The water will over flow and the sand will sink to the bottom.

I’ve used this method several times in the past. It probably stresses the fish worse putting them in a strange container than just leaving them in the tank.

Z rock,

thanks for the great advise. as with many things it is all in the preparation. I am planning on removing 70 lbs of gravel and replacing with 50 lbs of sand. still thinking through moving the fish and really cleaning the tank but your process would sure be faster.

i use plastic plants and run them thru the dishwasher with a little clorox and rinse the heck out of them. cleans em unbelievable well and fast.

I don't know about some people but by the time I chase all those fish around with a net and catch them I'm ready to call it a day!Me and the fish both will be stressed out!

Really you don't want to get to much into cleaning.There is bacteria on the glass and everything.Just changing out an old nasty substrate is freshening up the tank a tremendous amount.The faster this job gets done the less the bacteria dry out and the faster the tank will clear up and recover.

Thats another plus for sand.It's cheap so it can be tossed out and replaced without being out of anything.Anytime the nitrates run high it's probably not a bad idea to change out the substrate, or take it out and re-rinse it.

Your comments make sense to me. And lol I too would be stressed chasing the fish around the tank. I am going to try it your way. I need to get 50 lbs of sand cleaned before I begin.

Your idea of using a dust pan is great for removing the old gravel

Thanks again,

Mike

Sorry for bringing this old thread up again, but I'm probably gonna try to do this tonight. I am switching my 100 gallon from gravel to sand tonight. I got a good deal on some black sand from my lfs and can't wait to see what it looks like in my tank. I'll give an update as to how this worked for me when I'm through, hopefully tonight as long as I can get all 150 lbs. of sand rinsed. Not really lookin forward to that part of it, lol. I'll probably just do 135 or 140 lbs. and save the rest for extra when I need it from vaccuming.

Well, I made the change last night. Took my gravel out and replaced it with 120 lbs. of sand. Started at 10, finished it off just before 5 this morning. Part of why it took so long was because I was being kind of loud, kept waking up my son and had to get him back to sleep every time. I started off placing the sand in with a small-medium sized tupperware bowl, but after a while since I had to keep stopping, I ended up using a 1 Quart pitcher. It sped things up, but caused some more cloudiness. All and all, it looks great, a bit cloudy but that will go away. Thanks for the info on how to do this ;)
