Nicolas from Hawaii H2Grow, is the third person we have hired. He is by far the most comprehensive, reliable , competent, and easy to work with. Nicolas, has a natural affinity with all elements of pond service. His ascetics show through and his cost is much more reasonable than others. We are thrilled to have Nicolas!

I contacted Hawaii H2Grow to service our fish tank in a business office that had an influx of unsightly invasive snails, poor maintenance, and outdated deco. Nicholas knew right away the concerns I expressed and came to the rescue. He gave our big office tank a whole new makeover while ridding the invasive snails. We are pleased with his services and he is such a sweet and professional person. He is our new go to guy for all our aquarium needs! read more

Nicholas "Nick" is unprofessional and inconsiderate when scheduling my appointment. I contacted him to evaluate my koi pond that was leaking. He told me it will be Wednesday. I told as it gets closer, please let me know the approximate time of arrival. Since he did not show up or contact me on Wednesday morning, I texted Nick and his response he is coming at 2:00 p.m. I told it was past 2:00 p.m. He says, it now be Thursday. I told him that I moved my Wednesday appointments to accommodate his schedule to Thursday. No apologies. Nicholas did not even bother to arrange a reschedule. I have since learned his work is aquariums and not koi pond. It is a different skill set. Nick should have been honest about his experience working on koi ponds. read more

They came to our home to help with our aquarium concerns but while there Nicholas ALSO spent quite a bit of time helping us with problems with our pool waterfall that several other pool guys didn't know how to fix (water loss in our waterfall "riverbed". Grateful he stopped us from doing something we almost did that he mentioned caused one of the problems we were having (membrane breakdown / flaking). H2Grow is a company that demonstrated aloha to us. WE need more like this on the Island! read more

What a great resource! Nicholas is brilliant! Extremely knowledgeable on anything aquatic! From plants to pumps he has you covered! Oh and fish! Lots and lots of fish! Would definitely recommend H2Grow to anybody starting or maintaining an aquarium or outdoor pond! Mahalo!! read more

I am disappointed in the service we received from Nicholas. At first he seemed very nice and knowledgable but after we paid for the equipment or provided the down payment, he still wouldn't schedule an appointment. He was non committal and when he finally did come "after his other clients," he didn't make us a priority even after we paid for all the funds for the parts necessary. Once he did come, he wasn't prepared with the correct parts, didn't have enough PVC pipe to complete the job and needed to return several times. We also needed to have the pump grounded so it would be safe for a toddler to swim in. Nicholas recommended an electrician to ground the pump and said that he could come back at the same time as the electrician to complete the job the following day. The electrician came the following day but Nicholas messaged the same day to tell us that he wouldn't be able to make it until the following day. Because of this, we were given the expectation that the electrical would be completed when the electrician came. Instead, the electrician was only able to come for an estimate and told us he would not be available until the following week. We called for a second estimate and he came promptly and grounded the pump. Nicholas was upset with us that we didn't go with his friend and had the audacity to tell me I was behaving like a "mainlander." He told me the job would be $400 in cash in addition to the $2800 I already gave him- and when we wouldn't use his friend he demanded $580 instead of the $400 totaling $3,380 for a baby pool! We wanted to start a job July 16 and the job was still not completed and it's August 4th for a mini baby pool to have a new pump and filter installed. We decided to pay him for what he completed thus far and will be finding someone else to complete the job. read more

Thanks so very much Nick! My Auntie's pond "re-do" came out so beautifully! The Koi fish even look happier in the crystal clear water ! And we don't have to listen to the rattling of the old pump anymore LOL ! Who knew hooking up a new pump and filter would make such a difference! Thanks again ! Everyone - I highly recommend Nick ! read more

Nick was awesome!!!! I have no idea about ponds or any of the maintenance associated with them. I just bought a house in Nu'uanu which had a pond that had a lot of deferred maintenance.  He came over and was incredibly reasonable and explained everything clearly. He offered me different alternatives how to keep the pond in the best shape and all within my budget. He was honest and transparent. Highly recommend!!! read more
