Tap water is fineI am just at the thinking stage at the moment about changing my marine tank to a tropical set up.
My tank is a 4x 2 x 2 100 gal (english not US) with a 15 gal sump. The sump contains my filtration which I know will not be needed for a tropical set up
The tank and sump will have to be thoroughly cleaned to remove all coraline from the rear glass. There is a weir in the tank for the water return to the sump and the water is returned to the tank with a 5000LPH pump and I have 2 power heads in the tank, both of which are 6500 LPH each.
I was thinking of removing the weir and fitting new pipework to the sump to give more 'swim' room.
My lighting is a LED unit full length of the tank which is rated at 240 watt. This can be adjusted and in fact at the moment, I am only running at 65% for the marine system.
I would want to have a fully planted tropical set up and my main concerns are what water to use. tap water or RO water?
I use fast growing plants as the only filtration. You could even use the existing sump to grow plants in as a FW refugium. In that way you could have plant eating fish in the displayWhat will be the best form of filtration for the sump?
just adjust duration so the plants grow but not algae. I use 6500k shop lights but you probably still want to use the expensive stuff you already have.Will my lights be ok just turned down?
sure you can keep the powerheads but they are totally not necessary with most planted setups.Will I be able to use my present power heads or would it be advisable to get smaller ones?
Hope that helpsLooking forward to any advise.
